High-Head Dewatering Pumps
The GSZ-4-series is a submersible three-phase cast iron high head and high volume heavy-duty drainage pump driven by a 4-pole motor. 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 pump incorporates seal pressure relief ports that prevent the pumping pressure from applying to the shaft seal.
It is not recommended to operate the unit continuously along the dashed curve.
