APPLICATIONS
Designed
asa
low
cost
pump
for
:transfers, circulation, spill
returns, filtration
and
filling line use. Easily handles pure
solutions,
foaming
liquids,emulsions, suspended solids, gels
and ferments. Because the plastic
pump
is resistant
to
corrosion
and metallic contamination, it is
widely
used
for
pumping
photo
chemicals, plating
compounds,
labsolutions,
pharmaceuticals, cosmetics, weak acids,alkalie
s,
liquid
fe
rtilizers, insecticides, dyes, detergent
s,
waxes and
many
more.
