APPLICATIONS

Designed asa low cost pump

for

:

transfers, circulation, spill

returns,

filtrati

on and

filling

line use. Easily handles pure

solu

t

ions,

foaming

liquids,

emulsions,

suspended solids, gels

and ferments.

Because

the plas

t

ic pump is resistant to

corrosion and metallic contamination, it is

widely used

for

pumping photo chemicals, plating compounds,

lab

solutions,

pharmaceuticals,

cosmetics, weak acids

, alkalie
