Type PZH-500
APPLICATION
PZH pumps are designed to handle mine and industrial water containing solids having a maximum size of 50 mm wherein the density of the pumped liquid must not be greater than 1100 kg/m3, and the temperature to 30°.
Typical applications include:
High-performance intermediate pumping stations,
as the initial pumping pumps: melioration, dewatering, water supply.
Maximum immersion in the liquid – up to 2 m from the surface of the liquid to cable entry of the pump motor.
DESIGN
Submersible, centrifugal, vertical single-stage impeller pumps with helicoidal impeller mounted directly on electric motor shaft. Suction rose attached to the suction casing is the basis of the pump. Spiral discharge casing is finished with nozzle flange having an inner diameter 500 mm, about direction perpendicular to the axis of the pump. The pump is used three-phase asynchronous motor with degree of protection IP48 – with briefly closed impeller cooled with pump liquid – built-under the pumping system.
Handles for transport of the pump are located on the motor cover.
MATERIALS OF CONSTRUCTION
All components of PZH pumps are made of cast iron, besides suction rose made of constructional steel.
