The submersible FRP pumps with
stainless steel AISI 316L motors are used
for pumping aggressive and corrosive
liquids from disposal of wastewater of
chemical plants to various applications
with seawater.
Depending on its own know-how and
domestic production experience of
Fiberglass centrifugal pumps, FP has
been able to extend its production
program to these new submersible
pumps with original creation in
thermoset resins.
