Type OZ
Qmax=1200m3/h – Hmax=100m
APPLICATION
The basic application of OZ is open cast mine dewatering.
The OZ pumps are resistant to increased external loads and to the presence of solids and chemicals in the pumped liquid. Pumps must work in complete submergence. The capacity is up to 1600 m3/h and head exceeds 100 m.
For the sake of its design features the OZ pumps can be applied in any other situation where adverse operational condition occur, such as sand and gravel mines, raw water intakes etc.
DESIGN
Submersible, vertical single-stage centrifugal pumps with single-stream impeller mounted directly on the end of the electric motor shaft. The pumps are equipped with vane radial diffusers.
Hydraulic part is located above the motor. Between the hydraulic part and the motor there is an oil chamber with double mechanical seal. Since the chamber is subject to hydrostatic pressure the motor shaft seal is not subject to pump delivery pressure. Discharge flange is located at the axis of the pump and directed vertically upwards. The pumps can be installed on the bottom of the tank or hanged on the delivery pipeline.
The pump is driven by 400, 500 or 6000V electric dry and waterproof type motor designed for work in submergence up to 10 meters with IP X8 degree of protection.
MATERIALS OF CONSTRUCTION
OZ pumps are manufactured with three material versions: standard, wear-resistant and salt-resistant.
