The GPN-series is a submersible three-phase high power and extra heavy-duty slurry pump driven by a 4-pole or 6-pole motor. It is equipped with a high-chromium cast iron agitator that mixes settled matter into suspension for pumping. The other wear parts such as the impeller and the suction plate are also made of high-chromium cast iron for extra durability. The side discharge, spiral design allows smoother passage of the sucked solid matters. The motor is cooled by a water jacket that assures efficient motor cooling even when it operates with its motor exposed to air. The use of guide rail fitting system improves convenience in the facilities such as, iron works, ready-mixed concrete plants, and wastewater treatment plants where the pump is to be installed with a fixed discharge piping.
