System Compatibility

A wide variety of chemicals can be pumped.

Liquid end materials include glass-filled polypropylene
(GFPPL), PVC, styrene-acrylonitrile (SAN),
Polyvinylidene Fluoride (PVDF), PTFE, Hypalon,
Viton, ceramic, alloys and 316SS.

Immediate installation and start-up.

Included as standard accessories with all models
are an injection/back pressure valve assembly
and a foot valve/strainer assembly*, including
discharge and suction tubing.

Safe and easy priming and valve maintenance.

Included as a standard accessory is a bleed valve
assembly, including return tubing (available only on those
models with tubing connections).

Quick and economical liquid end
maintenance.

Available for every model is a
unique KOPkit®, a convenient,
economically priced, package
containing new cartridge check
valves and other important
spare parts.

Operating Benefits

Reliable metering performance. Our guided check valves,

with their state-of-the-art seat and ball designs, provide
precise seating, and excellent priming and suction lift
characteristics. Our timing circuit is highly reliable and, by
design, virtually unaffected by temperature, EMI and other
electrical disturbances.

Rated “hot” for continuous duty. Series C PLUS pumps
continue to meet their specifications for pressure and
capacity even during extended use. That’s because of
our high quality solenoid and special enclosure that
effectively dissipates heat.

High viscosity capability. A straight flow path and ample
clearance between the diaphragm and head enable standard
PULSAtron pumps to handle viscous chemicals up to a
viscosity of 1000 CPS.

Leak-free, sealless, liquid end. Our diaphragms are
of superior construction—PTFE-faced, bonded to a
composite of Hypalon and fabric layers, and reinforced with
a metal insert for optimum flexibility and durability.
