Type P-C
Qmax=120m3/h – Hmax=60m
APPLICATION
P-C pumps are designed to handle mine and industrial water containing solids.
Typical applications include:
Underground mines – for mine face dewatering, including cases where methane hazard or coal dust explosion hazard are present,
construction site dewatering.
DESIGN
Submersible, single stage impeller pumps with closed impellers mounted directly on electric motor shaft under the motor. The motor is cooled by the fluid pumped through a cooling jacket. The delivery flange is located at the upper part of the pump. Pump shaft is sealed by double mechanical seal in the oil chamber between the impeller and the motor.
The pump set is equipped with monitoring system consisting of motor bearings and windings temperature sensors, moisture sensors and electric protections against overload or dry run of the pump.
The pumps are compliant with Atex directive and are certified for operation at sites exposed to explosion hazard – I M2c, EEx dl.
Non Atex version of smaller mass is also available.
MATERIALS OF CONSTRUCTION
Standard version: impeller – wear-resistant cast steel, pump casing– aluminum alloy, shaft, bolts, nuts – stainless steel. In salt-resistant version all elements are made of stainless cast steel.
