Hydraulic Diaphragm Metering Pump
Pulsafeeder Expertise
Since 1936, Pulsafeeder has been the global leader in fluid handling technology and innovation in
chemical dosing. Pulsafeeder has built a foundation of success with thousands of installations in fluid
handling applications. Our extensive product breadth enables us to provide the convenience and efficiency of single-source solutions across various industries.
PULSA Series® Pumps
Well known for its rugged design and history of long service, the PULSA Series positive displacement, reciprocating metering pump has remained a customer favorite for over seventy years. PULSA
Series pumps combine the high efficiency of a plunger pump with the sturdiness of a diaphragm
seal to eliminate leakage. Available in a range of materials, PULSA Series pumps can handle most
chemicals. The PULSA Series pump is the “go to” pump for reliability and success.

Diaphragm Technology
Suction Stroke Discharge Stroke
Flat Diaphragm (TFE & Metal) TFE Shown
The popular flat diaphragm reagent head is available in
a variety of materials and can handle a wide range of
chemicals. The dish plates prevent over deflection of the
diaphragm. There is no contact with moving parts. With
typical diaphragm thicknesses of .060” (1.52mm), this is
one durable diaphragm.
Suction Stroke Discharge Stroke
Hydratube®
The Hydratube is the choice for high viscosity slurries.
Its straight, large, flow through design eliminates clogging and flow restrictions. Available in FKM, CSM or
PFA, it can be utilized with the most corrosive or acidic
chemicals.
Hydracone®
The Hydracone’s self-priming head features a conical elastomer diaphragm. It is particularly well suited
for high-lift conditions, high viscosities, and low density
slurries. The Hydracone is available in a choice of high
performance fluorocarbon elastomers such as FKM and
chlorosulfonated polyethylene (CSM).

Pulsafeeder Engineered Solutions
Pulsafeeder Engineered Solutions provide
out of the box, ready to connect to your piping convenience. Packaged solutions arrive as
complete systems with all ordered controllers
and accessories. They are piped, valved, wired,
tested, and ready to perform.
Our skid systems are built with an intuitive
layout for easy maintenance and requires no
specialized tooling. We factory warranty all skid
systems for one full year. Each system undergoes a complete system performance test prior
to leaving the factory.
For assistance in developing your next Pulsafeeder skid system, please contact our system application engineers at (585) 292-8000.

Parts & Accessories
A KOPkit® (Keep On Pumping) can help you cut downtime
and put you back in business
fast. Use KOPkits for preventive maintenance and to ensure
continuous high performance
from your Pulsafeeder metering
pump.
Calibration Columns
These columns are constructed of clear PVC
tubes with PVC end caps
or an option for Borosilicate glass with Teflon end
caps and should be sized
for a 30-second draw
down.
Pressure
Relief Valves
prevent an
overpressurization
situation from ever damaging
your pumps or pumping system. Overpressurization can
occur when a valve is closed
or a blockage occurs. They are
always recommended equipment for any pump or skid system.
Pulsafeeder’s Pulsation Dampeners improve pump system efficiency by removing pulsating
flows from positive displacement
pumps.
Pressure Gauges are relied on to measure pressure
in the system. Proper pressure is necessary to insure
flow. Pulsafeeder Pressure
Gauges are accurate and
reliable.
Leak Detection
Sensor technology sandwiched
between double diaphragms
alert you at the first sign of leakage to prevent a small leak from
becoming a large one.
Back Pressure Valves provide positive back pressure
for systems with less than
the minimum required discharge to assure optimum
metering performance.
