sewage pump

Description

Design:

Vertical, single-stage, close-coupled submersible motor pump with various impeller types, for wet-well installation, stationary or portable design.
KRT is the safe, reliable and energy-efficient solution for all pumping jobs in municipal and industrial waste water Engineering.
In developing the KRT, NSP Co. Engineers aimed at maximum versatility / flexibility of application by offering the pump in a various materials.
Protection against excessive temperature rise in the motor winding, absolutely watertight cable entries and bearings dimensioned to give long service lives are features enabling long, trouble free pump operation.
