Watson-Marlow Bredel pumps are used in a wide variety of
fluid transfer, metering, and dispensing applications across a
range of processing industries. Following are examples of
applications in which Watson-Marlow Bredel pumps have
succeeded where other pumps failed.
CHEMICAL
Accurate and repeatable metering of
process fluids into dispersion mills is
critical in achieving uniformity from
one batch of paint pigments to another.
Because of their ability to provide
consistent, reproducible flows at low
volumes, Watson-Marlow peristaltic
pumps were chosen to replace double
diaphragm pumps at BASF’s Michigan
paint mixing plant. The pumps require
minimal set-up time and maintenance.
The sealless design eliminates the need to clean the pumps thereby
avoiding the costs, health risks, and environmental issues associated
with cleaning solvents.
Easy cleanup, high flow rates,
and precise metering are the
key reasons why Eastman
Kodak uses Watson-Marlow
peristaltic pumps at its Rochester,
New York, plant. Photographic
chemicals are dissolved in a
solvent and the solution is then
dispensed in extremely precise
amounts under computerized
control into bottles using Watson-Marlow pumps. Minimal pump
maintenance consists of periodic flushing of tubing or, in some cases,
simply replacing tubing in which polymer buildup has produced
a blockage. Quick, easy cleanup is important since solutions are
constantly changing and tubing must be cleaned before each change.
Sony Manufacturing Company
UK uses Watson-Marlow peristaltic pumps in the production
of its Trinitron® television tubes.
As tubes are moved into position
by an automated production
line, sensors signal the pumps
to begin feeding a solution of
carbon GA-37, potassium silicate, and silicon carbide to a sponge
head which coats the necks of the tubes. The peristaltic pumps
replaced gear pumps, significantly reducing maintenance costs and
eliminating the need to import costly spare parts.
As part of bulb degassing operations
at Osram Sylvania’s Hillsboro, New
Hampshire plant, Watson-Marlow
pumps are used to apply a highly
corrosive solution of zirconium and
alcohol to miniature automotive light
bulbs. Pump speeds are programmed
to meet the different throughput rates of the plant’s four application
machines. The tubing easily withstands the damaging effects of
the zirconium solution.
A large southeastern
US company produces
calcined kaolin clay, a
white clay used by
paper companies as a
filler and coating to
increase the opacity
and ink absorption of
certain paper stocks.
In the production
process, the clay, in
slurry form, is heated to 1800˚F, changing its mineral structure and
improving whiteness, brightness, opacity, and glossiness.
Pumping the clay too rapidly causes shear and thickens the slurry.
The company had been using centrifugal pumps to transfer the clay
very slowly, but the pumps required constant maintenance to
replace leaking seals. By switching to Watson-Marlow Bredel hose
pumps, the company was able to pump the clay mixture at higher speeds without shear-induced thickening. The hose pumps also
eliminated the problems and maintenance costs of leaking seals.
A west coast electric utility generates
a portion of its total power demand
with geothermal steam. The steam
contains sulfur which must be
stripped from the off-gas before
it is released. In this process, an
extremely corrosive high sulfur
slurry is pumped to a filter belt press
where excess liquid is removed and
solids are deposited in a cake tank. The solids are then reslurried,
pumped to a melter, melted, and the sulfur is decanted into a storage
tank. Faced with excessive maintenance to repair damaged and
corroded pump parts, the utility tried several types of pumps before
installing Watson-Marlow Bredel hose pumps. The pumps have proven
exceptionally reliable and have dramatically reduced maintenance
and repair costs.
MINING
At a large Nevada mine, a concentrated
lead slurry is transferred for shipment
to another plant for additional refining.
Containing concentrations as high as
60%, the slurry is very heavy and
abrasive. The mine recently installed
a Watson-Marlow Bredel hose pump
to transfer the concentrated slurry at a
rate of about 30 gpm at pressures above 50 psi. The centrifugal pumps
that were used previously were constantly shutting down because
the required flow rates were too close to shutoff. The mine also found
that the low flow rates chewed up the stators of progressive cavity
pumps, requiring constant maintenance and excessive downtime. The
Watson-Marlow Bredel pump easily handles the low flow rates and
pressures and has significantly reduced maintenance times and costs.
PULPAND PAPER
PRINTING
Precise, consistent, repeatable flow rates and minimal
maintenance are the primary
reasons why Boise Cascade
switched from diaphragm
pumps to Watson-Marlow
peristaltic pumps for dye
addition. Overall shade losses
at Oxford Specialty Papers
Division were costing as
much as 60 tons of off-quality paper a month. In addition, stripping,
cleaning, and repair of the diaphragm pumps were causing excessive
downtime and lost productivity. Since installing the Watson-Marlow
pumps, losses due to color irregularities have been negligible and
productivity has increased substantially. Maintenance now consists
of only scheduled tubing changeovers which take only minutes.
McCorquodale Envelopes, Wolverton,
Buckinghamshire, England, produces and prints
approximately 7 million envelopes every day.
In the printing process, inks are pumped from
containers into the chambers of each of 12
Winkler and Donnibar printing presses. Several
years ago, after experiencing unacceptably high
downtime and ink color changeover times, the
company switched from impeller pumps to
Watson-Marlow Bredel peristaltic pumps. The pumps have dramatically
simplified and shortened the changeover from one color to another.
The process (which used to take hours) now takes only minutes and
consists of simply changing a tube.
McCorquodale originally installed smaller 500 Series pumps. The
company recently purchased several new close-coupled pumps, citing
their exceptional performance and lower purchase and lifetime costs.
Precise metering of dyes is critical in
the production of the “highly dyed”
(day-glo and vibrantly colored) papers
made by Simpson Paper. Eighteen
Watson-Marlow pumps are currently
in service at the company’s Pomona,
California mill, metering brightly
colored dyes and optical brighteners
(to the paper machine system). The
pumps replaced piston pumps which
clogged frequently, causing downtime, lost production, and high
maintenance costs.
At Waddington’s, a UK-based printer,
the varying requirements of different
print jobs necessitate that varnish be
pumped from a container to a coating
tray on a multicolor printing press with
precise control across a wide range of
flow rates. To achieve a consistent,
high-quality finish, the varnish must
be pumped gently to avoid foaming
and entrapment of air bubbles. The
double-diaphragm pumps formerly
used were expensive to maintain and
their inconsistent flow rates produced poor quality coatings. With the
low-shear Watson-Marlow peristaltic pumps chosen to replace the
diaphragm pumps, coating quality has improved sharply and the time
consuming job of stripping and cleaning pumps has been eliminated.
ADHESIVES
When a highly viscous and abrasive
adhesive used in the manufacture
of various automotive components
kept causing gear pumps to seize,
Ford Electronics replaced the pumps
with Watson-Marlow peristaltic pumps.
The highly viscous (25,000 cps)
adhesive, which contains metal, is
pumped in two parts by two WatsonMarlow pumps and is combined in a
static mixer as it is applied. The pumps run 16 hours per day
and provide precise, repeatable flow rates which ensure the optimal
mix ratio of the adhesive components required to maximize adhesive
strength and performance. Pump wear has been virtually eliminated,
and now, when the adhesive cures within the pump, cleanup is as
simple and fast as replacing the tubing.
SEMICONDUCTOR
A mid-Atlantic manufacturer of
capacitors and other electronic
components. In its production
process, the company pumps a
highly abrasive ceramic slurry
consisting of about 10 different
powders, a dispersent, and water
into an attrition mill which mixes
the ingredients and breaks up
lumps. Watson-Marlow Bredel
hose pumps then pump the slurry from the bottom of the mill
through cooling chambers, and redeposit it at the top of the mill in
order to maintain the desired slurry temperature. The pumps, run
constantly at flow rates of 3-5 gpm, and have virtually eliminated
downtime for maintenance. The company also uses smaller
Watson-Marlow Bredel tubing pumps at other locations in its
process for metering and dispensing chemicals.
BIOTECHNOLOGY
PHARMACEUTICALS
Genetics Institute, Inc.,
Andover, Massachusetts,
uses Watson-Marlow
peristaltic pumps in the
production of recombinant
blood and bone proteins to
assure that process fluids
and buffer solutions are
handled and moved without contamination. As media
are transferred from pressure
vessels through membranes
for separation filtration, fluids
are totally contained within
tubing and protected from
contact with pump parts and other sources of contamination. In
other processing operations, probes continuously sense pH values
of solutions and signal Watson-Marlow pumps to precisely meter
titrin as needed.
At Bristol-Myers Squibb Company’s
New Brunswick, New Jersey plant,
Watson-Marlow pumps help assure
absolute sterility in various filling
operations. The pumps, which are
used in the production of contrast
agents for intravenous injection prior
to MRI, X-ray, and similar examinations,
have also improved productivity.
Filling of vials that once took 15-20 minutes per batch is now
accomplished in seconds. The continuous, sterile, nonmetallic
pathway through the pumps assures complete protection from
particulate generated by motors as well as other contaminants.
The gentle action of the pumps has no adverse effect on the
product. Pumps also provide precise metering and maintain
their calibration, eliminating the need for recalibration midway
through a run. Built-in microprocessor controls fill accurately at
throughputs ranging from .5 ml to 13 liters per minute.
Irvine Scientific, a
leading U.S. manufacturer of tissue
culture media and
specialty products,
uses Watson-Marlow
pumps to fill containers with batches
from a few liters to
18.5 liters. The pumps
provide the high accuracy and reliability required to pump a
multitude of products in a wide range of fill volumes.
At Ciba Geigy’s Suffern, New York plant, Watson-Marlow pumps
are used to apply an accurate, pulseless stream of drug and adhesive
materials onto estrogen transdermal patches for menopause therapy.
The drugs are completely contained within the tubing, preventing
employee exposure, allowing rapid changeovers, and eliminating
pump cleaning.
New Brunswick Scientific
produces a wide array of
bioprocessing equipment
for applications ranging
from seed culture development to downstream
processing, including
fermentation equipment
and instrumentation
systems for cell propagation, process monitoring
and control, biomass
separation, and product
concentration. The company uses Watson-Marlow pumpheads
on its computer-controlled fermentors to precisely meter acids,
alkalis, and antifoaming agents. Pumpheads are also used for
nutrient feed on models designed for continuous culture.
Accurate and repeatable flow rates are the
primary reasons why Pfizer Inc’s Vigo Plant
in Terre Haute, Indiana uses several
Watson-Marlow pumps to feed sugar
nutrients to lab-scale fermentors. Controlled
by a timer and process signal, the pumps
provide consistent flow rates from 1 to 7
ml/minute. Process fluids are confined
within the tubing thus ensuring complete
sterility of all flows to the fermentor, and the gentle pumping action
does not harm the shear-sensitive fluids.
A contract research company which
performs independent safety and
efficiency evaluations of pharmaceutical products, Pharmaco Life
Science Research uses a WatsonMarlow pump to fill vials with small
doses of diluent. The microprocessorcontrolled pump dispenses 2.2 ml of
sterile diluent into each vial with an accuracy of 0.5%. Selected
for its high accuracy, long-term repeatability (without need for
recalibration), and flexibility, the menu-driven pump can be
quickly reconfigured for dose size, number of doses, and time
interval between doses.

A canning operation located near San
Francisco uses a Watson-Marlow Bredel
hose pump to transfer sliced peaches from
holding tanks to its canning line. The pumps
operate at 14 rpm, transferring a 50/50
mixture of peaches and water at a rate of
150 gpm or 9 tons per hour. The company
had been using centrifugal pumps, but was
experiencing a high percentage of damaged peaches. The soft
pumping action of the Watson-Marlow pump eliminates shear,
keeps the peaches intact, and has dramatically reduced the amount
of damaged or unacceptable produce.
The company also likes the dependability and low maintenance
of the pump. Processing of perishable produce is very time sensitive.
The Watson-Marlow Bredel pump runs continuously 24 hours a day,
7 days a week for the entire 7 to 10 week canning season.
COSMETICS
At the Elizabeth Arden Research and
Development Center in Trumbull, Connecticut,
a Watson-Marlow pump transfers oil and waxes
heated to 95˚C to kettles as part of a pilot plant
emulsion-making process. The emulsions, which
are used in the manufacture of cosmetics, must
be precisely metered to ensure product quality
and prevent spoilage. The pumps ensure accurate,
repeatable flow rates that can be readily increased
for full-scale production. Pumps are easily changed
over from one liquid to another by changing tubing or flushing it
with water.
WATER AND WASTE TREATMENT
Pump corrosion and maintenance were
constant—and costly—headaches at the
Ipswich, Massachusetts Municipal
Water Department. Excessive downtime
and the cost of replacement parts forced
the treatment plant to replace diaphragm
pumps with Watson-Marlow peristaltic
pumps for metering chemicals such as
sodium hypochlorite, aluminum sulfate,
sodium aluminate, alum hydroxide,
fluoride, and potassium hydroxide. With consistent, accurate
feed rates the pumps now meter the chemicals under process
control to match raw water flow. Enclosed in IP55 cases for
washdown protection, the pumps run 12 hours a day. Since
the installation of the pumps, maintenance costs and downtime
have nose-dived from 20% down to 0%.
Process effluent from a polybutylene
resin manufacturing process at
Shell Chemical, Taft, Louisiana, is
treated with a polymer flocculant
before being discharged into the
Mississippi River. The sticky, viscous
polymer solution would build up
and clog the check valves of the
diaphragm pump which had been used to meter the solution at
low flow rates (cc/min.). The diaphragm pump was replaced with
a Watson-Marlow pump that does not clog and provides precise
control at low speeds.
Dramatically reduced maintenance and resistance to
corrosive chemicals were
the chief reasons in selecting
Watson-Marlow pumps for
service at the Niagara
County Sewer District #1
wastewater treatment plant in Niagara Falls, New York. With
no check valves to clean, there is no need to disassemble the
pumps, and cleanup is as simple as rinsing or replacing the
tubing. Marprene® tubing supplied with the pumps resists the
corrosive effects of chemicals such as sodium hydrochlorite and
ferrous chloride used in wastewater treatment. Of the three
pumps presently installed, one works under automatic control
off a flow meter in a remote area of the plant. Two new ferrous
chloride feeding points are now being installed as part of a
pump station intercepter extension project.
To ensure the high quality of drinking
water in several English water districts,
Severn Trent Atec continuously
monitors filtered water for cryptosporidium bacteria. Watson-Marlow
pumps, operating 24 hours a day in
the cold, damp conditions of outdoor
kiosks or filter houses, deliver constant
volume water samples to turbidity monitors. Watson-Marlow IP55
ingress-protected pumps were selected because of their ruggedness,
reliability, and ease of maintenance.
At a Carolina wastewater
treatment plant, 5000-6000
MLSS sludge is pumped into
a diffuser air flotation thickener
where polymer and dilution
water are added. Through
flocculation, the sludge is
thickened to 60,000 - 70,000
MLSS and wiped off into a wet
well. Watson-Marlow Bredel hose pumps then pull the thickened
sludge from the bottom of the wet well and pump it to a filter
belt press where excess water is removed. The dewatered sludge
is then sent to a pug mill where it is mixed with kiln dust or lime
and allowed to thicken and dry. According to plant officials, the
Watson-Marlow Bredel pumps not only handle the highly viscous
slurry with no trouble, they have no seals to replace, significantly reducing maintenance costs.
At the Massachusetts Water
Resources Authority (MWRA)
Deer Island Wastewater
Treatment Plant, influent is received
through several 4- to 6-mile pipelines
under Boston Harbor. After preliminary
processing, the influent goes through
a scrubdown to reduce hydrogen sulfide
content from as much as 250 ppm to
less than 0.1 ppm. Watson-Marlow Bredel
hose pumps are used in this process to
transfer and meter sodium hypochlorite,
sodium hydroxide, and sodium bisulfate. After experiencing high
downtime, high maintenance costs, and disappointing performance
with diaphragm and other types of pumps, plant engineers switched
the process over to the Watson-Marlow Bredel pumps. Used in other
processes within the plant, the pumps provide trouble-free service and
extremely low maintenance. MWRA engineers are now evaluating
a 100 mm duplex hose pump for another process.
When GE Plastics, a producer of
polycarbonate resin pellets, experienced problems pumping effluent
containing waste plastic strips up to
10” long, they switched to WatsonMarlow Bredel hose pumps. The
strips were becoming trapped in
the double-diaphragm pump the
company was using to transport the
effluent to a filter press. Constantly
blocked, the diaphragm pump was
in effect, acting as a filter. The
Watson-Marlow Bredel hose pump transfers the effluent easily,
virtually eliminating downtime. It has also improved the effectiveness
of the filter press by as much as 35 times.
AGGREGATE
Most cement trucks cannot or
will not handle small batches
of concrete. However, trucks
manufactured by Margar
Industries, Inc., of Eaton,
Colorado, include a patented
mixing system for producing
small batches as needed. The
system bolts onto the truck
and uses a Watson-Marlow
peristaltic pumphead to
precisely meter various chemicals, which affect the concrete’s
strength, performance, and drying time, into the concrete mix. The
pumpheads require only periodic tubing changes and are unaffected
by the dirty abrasive environment.
When a large Texas construction
company needed several pumps
to transfer a cement mixture
containing water, sand, sulfate
cellulose, and additives at pressures of 200 psi and flow rates
of 300 gpm, they called their
Watson-Marlow Bredel representative. The rep recommended a unique duplex hosepump,
which consisted of two pumpheads mounted on a single
drive shaft. Each pumphead has two shoes 180˚ apart which compress a hose to produce flow. With the pump shoes staggered at
90˚ intervals, the pump is capable of producing higher flow rates
than a single pump, but with much smaller power and space
requirements than two pumps. The staggered pump shoes also dramatically reduce pulsation in the hose, producing a much smoother
flow. The pump easily transfers the abrasive mixture and requires
only minimal maintenance to change hoses every 6 months.
OEM
B. Braun Biotech, the world’s leading
supplier of fermentors for use in biotech
and pharmaceutical processing, typically
uses no less than three Watson-Marlow
pumps and/or pumpheads in all of their
standard products. The pumps and
pumpheads individually meter acids, bases,
and antifoaming agents (surfactants).
Watson-Marlow products were selected for
their consistent, accurate flows, versatility,
compact size, and price competitiveness.
Packard Instrument Company,
leading manufacturer of life science/
research instrumentation, chose
Watson-Marlow peristaltic pumps for
their MultiPROBE™ line of automated
liquid handling systems. Designed for
high throughput sample processing in
clinical, pharmaceutical, and biotechnical applications, MultiPROBE Systems
required a long-lasting pump capable of high throughput/high
volume liquid dispensing to wash interior and exterior surfaces of
sampling tips. Watson-Marlow pumps prevent sample-to-sample
contamination and eliminate the need for traditional time-consuming
and less efficient washing with syringes. Extended tube-life and easy
serviceability enabled Packard to include the pumps as a standard
feature on all of their MultiPROBE Systems.
After extensive testing, M&O Perry
Industries, Inc., Corona, California,
approved Watson-Marlow pumps for
use on automatic filling and closing
systems. The contamination-free pumps
are used in biotech and pharmaceutical
applications which require sanitary
filling at rates of 10 to 50 fills per minute
and where sterility is a must. Compact design, accuracy, dependable
operation, and ease of changeover and cleaning of the pumps were
listed as important considerations in the decision.
OTHER APPLICATIONS
Leaves which fall onto railroad
tracks in autumn are ground
into a slippery varnish-like
coating on the rail surface by
the weight of passing trains.
Borrowing a solution to the
problem from British Rail in
the UK, Long Island Rail Road
of New York uses Watson-Marlow
peristaltic pumps to spray a gel containing large amounts of
abrasive grit onto the tracks at night to improve traction.
A. Lockett & Company, textile printer/
finisher in Salford, England, replaced an
air piston pump used to transfer print
paste with a Watson-Marlow peristaltic
pump. The paste, which contains an
aqueous dispersion of pigment colors
and white fillers, is pumped at flow rates
from 1 to 40 gallons per hour. Because
Watson-Marlow pumps are reversible, self-priming, and can run dry
safely, excess paste is pumped back into the container at the end of a
print run and waste has been reduced at start-up. Color changeovers
are accomplished quickly and easily by changing the tubing.
