Complete Economical Selection

Nineteen distinct models are available, having pressure
capabilities to 300 PSIG @ 3 GPD, and flow capacities to
504 GPD @ 20PSIG, with a turndown ratio of 100:1. Metering
performance is reproducible to within ± 2% of maximum
capacity.

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
(*not avail. with high viscosity connections for >3000 CPS).

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 and < 240 GPD).

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 E 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 3000 CPS. For higher vicosity applications,
larger, spring-loaded connections are available.

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.
