Type PZD-250

Qmax=500m3/h – Hmax=17,5m 


PZD pumps are designed to handle mine and industrial water containing solids having a maximum size of 14 mm wherein the density of the pumped liquid must not be greater than 1100 kg/m3, and the temperature to 30°.

Typical applications include:

underground mines – as the initial pumping pumps,
municipal economy.


Submersible, centrifugal, vertical single-stage impeller pumps with dual stream closed impeller mounted directly on electric motor shaft. Suitably shaped discharge casing is finished with nozzle flange having an inner diameter 250 mm, directed vertically upwards. From the side of the intake, impeller is closed with two suction caps. Due to the use of dual-rotor pump has a two suction rose made of perforated sheet metal and located on both sides of the discharge body. The pump is used three-phase asynchronous motor with degree of protection IP68 – with briefly closed impeller cooled with pump liquid – built-under the pumping system.

PZD pumps can be installed on the bases at the bottom of the reservoir or suspended by the handles.


PZD pumps are made with two different voltage versions 400 V and 500 V in the basic version of the materials.
