Single Stage End-Suction Centrifugal Pumps
Weinman versatile, low cost pumps are engineered
for use on most phases of liquid handling. These
frame mounted, end-suction pumps are heavy
duty, general purpose centrifugal pumps with
heavy wall castings suitable for many commercial
and industrial applications, such as
condenser, chilled and hot water
systems in HVAC and process
secondary pumping. High efficiency,
robust case construction of cast
iron and impeller construction
of bronze makes these pumps an
ideal selection for applications that
require easy-to-maintain, reliable,
long lasting pumps.
