WHY USE GEAR PUMPS?
Gear Pumps are positive displacement
pumps that are frequently used for
metering and transferring viscous as
well as thin fluids at higher differential
pressures.
Liquiflo has extended the useful range
of gear pumps into low-viscosity fluids
by using a wide variety of non-metallic
self-lubricating components.
Gear pumps are an economical
alternative to Diaphragm pumps for
metering applications and do not pulse
or require an air source to operate.
They generally last longer in continuous
duty applications than Diaphragm,
Progressive Cavity or Peristaltic pumps
that require frequent part replacements.
However, the real value of a gear pump
derives from the flexibility and availability
of materials of construction and the
sealing arrangements which facilitate
optimizing the pump for the given
service.
Advantages and attributes over other
types of pumps are:
◆ Low flow and high discharge
pressure
◆ Virtually no pulsations
◆ Self-priming
◆ Lower NPSHR
◆ Fewer wearing parts
◆ Less auxiliary equipment required
(pulsation dampeners, compressors,
dryers, etc.)
◆ Flow accuracies as low as 0.5%
are achievable
◆ Easy to repair

Liquiflo’s standard Inner
Magnets are made from
Samarium Cobalt which can
be used at elevated
temperatures.
WHY USE MAG-DRIVE
GEAR PUMPS?
Magnetically Coupled Pumps offer
a simple and cost effective solution to
sealing toxic, noxious, crystallizing or
most other fluids that present problems
for single seals and would therefore
require use of a double mechanical
seal. Magnetically-coupled pumps
eliminate the need for cooling loops
that are required by double mechanical
seals. Two problems commonly
associated with cooling loops are
selecting a compatible barrier fluid
and disposing of the barrier fluid in
the event of an inboard seal failure.
Liquiflo has been producing
magnetically coupled pumps for
more than twenty years with tens of
thousands of successful applications.
Magnetically-coupled versions are
available for all of Liquiflo's product
lines including 2, 3, 4, & H-Series
Gear Pumps, and the Centry®
Series Centrifugal Pumps.
Advantages of Mag-Drive Pumps:
◆ Less expensive than
double-sealed arrangements
◆ Eliminates cooling loops required
on double seal arrangements
◆ Eliminates the need to dispose
of barrier fluids

Liquiflo Gear Pumps handle a wide range of applications including the pumping of
low-viscosity and high-viscosity fluids, as well as complex metering applications.
High-Viscosity Fluids
Low-Viscosity Fluids
Metering
Water treatment polymers and food
materials up to 80,000 cps are typical
of the high-viscosity service of the
Rotogear® Series of gear pumps. On
high-viscosity applications, it is preferable
and more efficient to use larger pumps
running at slower speeds.
Frequently, gear pumps are the
preferred solution in low-viscosity
pumping applications because of
their hydraulics (low flow, high pressure
and pulseless flow), compactness,
efficiency and low cost. Liquiflo’s wide
selection of materials allow for pump
customization to reduce premature shaft,
gear, and bearing wear on low-viscosity
fluids. Liquiflo has successfully pumped
liquids with viscosities as low as 0.3 CPS.
Liquiflo gear pumps are used in
variable flow systems where the motor
RPM is controlled to regulate pump
output. Flow rate, pH levels or RPM can
trigger the control of feedback signals.
(Refer to the Engineering section for
more details on gear pumps in
metering applications). The Rotogear®
Series is available in a wide variety
of flow ranges (11 sizes offered),
simplifying selection for metering
applications.
REPAIR KITS
Repair Kits simplify inventory and
speed repair. All parts can also be
purchased separately.
Repair kits contain all components
to completely rebuild your Liquiflo
Gear Pump to like-new condition
(all items except the housings
are included).
Repair Kits Include:
• Gears
• Bearings
• Shafts
• Wear Plates
• Keys
• Pins
• O-Rings
• Retaining Rings
• Seals (if applicable)
RELIEF VALVES
Positive displacement
pumps should be installed
with a relief valve in the
discharge line. This will
protect the pump and
piping against any type of
line blockage including
the inadvertent closing of
an isolation valve. Liquiflo
manufactures two sizes
of relief valves in both
316 SS and Alloy-C.
CARTRIDGE
A cartridge is a complete
mag-drive pump less the
outer magnet and pedestal.
A cartridge replacement is a
convenient way to quickly
replace a pump that requires
maintenance.

H-Series
Up to 225 PSI
differential pressure
Liquiflo’s H-Series high-pressure
gear pumps are available in Sealed
and Mag-Drive versions with flows
up to approximately 30 GPM and
differential pressures up to 225 PSI*.
With similar outside dimensions to the
3-Series, the H-Series has larger shafts,
bearings and seals for extended service
life. These features allow it to handle
higher pressures and operate longer.
* 300 PSI possible on some models.

General: Depending on the model, the
Centry® Series centrifugals are available
as standard with closed impellers. Closed
impellers eliminate axial loads and extend
the life of the motor bearings when the
pump is close-coupled to the motor.
Closed impellers simplify the axial positioning
of the impeller, when using close-coupled
sealed pumps.
Single Mechanical Seals:
* Suction Port Size x Discharge Port Size x Impeller Diameter
Single mechanical seals are the most
economical type of seal to use when
leakage is not desired. When properly
installed and maintained, these seals will
generally give years of trouble-free service.

Double Mechanical Seals:
Double Mechanical seals are also available
for the Liquiflo Centry® Series centrifugal
pumps. This seal configuration relies on a
barrier lubrication system to cool and
lubricate the seal faces.

Magnetically-Coupled Pumps

These offer a simple and cost-effective
solution to sealing toxic, noxious, crystallizing
or most other fluids that present problems for
single seals and would therefore require use
of a double mechanical seal. Magneticallycoupled pumps eliminate the need for
cooling loops that are required for double
mechanical seals.

SPECIALS
One of Liquiflo’s many strengths is their
ability to design and manufacture Specialty
Pumps. A Special Pump can be as simple as
modifying a port configuration or as complex
as a complete new pump design. Liquiflo’s
design and manufacturing engineers use their
years of pumping experience and knowledge
of engineered materials to custom design a
pump to meet specific applications. To date,
Liquiflo has designed over 700 different
specialty pumps which have solved numerous
problems in the chemical and industrial
marketplace throughout the world.
If you have an application that cannot use a
standard off-the-shelf pump, please give us
the opportunity to design a custom pump that
will meet the specific needs of your
application.
A few examples of Liquiflo’s custom designed
pumps are described and shown below.
“High Viscosity” Pump
Challenge: To pump a mastic with a viscosity similar to caulking at a
differential pressure up to 500 PSI and suction pressure of 1000 PSI. The pump
needed to be mounted on a 4-axis robotic head where it needed to discharge
a bead of mastic at a maximum rate of 17 linear feet per second. In order to
keep the inertia to a minimum, the pump needed to weigh less than 10 lbs.
Solution: A variation of the 37 Series was used. The pump casings were
made of aluminum to help minimize the weight. The internal construction was:
hardened steel gears, wear plates and shafts, sintered bronze bearings isolated
from the pumpage by polypac seals and externally grease lubricated. The
pump was close-coupled to a hydraulic motor and operated at a maximum
speed of 50 RPM. From design to shipment, the working prototype was
completed in just under eight weeks, and full-scale production was
completed within sixteen weeks.
“Ultra-High Pressure” Mag-Drive Pump
Challenge: Custom requirements were for a mag-drive pump that
could handle system pressures up to 1500 PSI (100 bar).
Solution: Containment Can and housings had to be designed to
withstand the unusually high pressure without catastrophic failure or
distortion that would affect operating characteristics. A solid 316 SS bar
stock body with extra heavy bolting was used in conjunction with an
extra heavy-walled containment can to withstand the extremely high
pressures. Test pressures of the newly designed pump exceeded
4500 PSI (300 bar). From design to shipment, the working prototype
was completed in under ten weeks.

“Glove Box” Nuclear Pump
Challenge: A pump was required for processing high-grade plutonium.
The pump needed to be mounted inside the “glove box.” The motor would
be mounted on the outside of the glove box and the pump would be
mounted on the inside of the glove box. In addition, due to the radioactivity
of the material being pumped, a further requirement was to have the ability
to remove the pump cartridge and/or the motor, without creating a breach
in the glove box wall.
Challenge Us
Solution: A double containment shell solved the problem. One containment
can was mounted to the pump in the normal manner while the second
containment can was mounted to the glove box wall. This configuration
maintained closure in the event that either the pump or the motor needed
to be removed for repair or replacement.
With Your
Toughest
“Bromine” Plastic Gear Pump
Pumping
Challenge: The requirement was to pump pure liquid bromine at a
differential pressure of 30 PSI.
Applications
Solution: This is one of a number of gear pumps that Liquiflo made
from plastic. This pump in particular was a Kynar version of a 35 mag drive
with Kynar coated inner magnet and containment can, tantalum shafting,
and unfilled Kynar housings. Other engineered plastics that Liquiflo has
manufactured gear pumps from include CPVC for herbicide service,
PTFE for ultra pure water service and Ryton for various services.
“Super Bullet” (Colloidal Suspension) Pump
Challenge: The requirement was to build a non-pulsing positive displacement
pump for pumping water containing colloidal silica for the paper industry.
The colloidal silica particles are extremely abrasive and small in size – just 2-10
microns. These abrasive particles work their way into the smallest of crevices
and accelerate wear of surfaces that exhibit any relative motion. The
customer found it impossible to find a pump that would last more than
a few weeks in this extremely difficult service.
Solution: Liquiflo’s designers solved this challenging application using a
variety of engineered materials that would work well together even in an
extremely abrasive environment. They also redesigned the internal
configuration of the pump to minimize the abrasive action that normally
takes place. After an extended effort, the chosen materials for the internals
of the pump were SiC on SiC bearings, and bearing-grade PEEK gears. A
small amount of carbon graphite was added to the inner SiC sleeve bearing
to give it some self-lubricating properties. With a service life now in excess of
12 months, our satisfied customer respectfully nicknamed it The “Super Bullet.”
