OWH pumps are stationary, horizontal multistage pumps.
The discharge port is directed vertically upwards, and the suction port is directed horizontally to the left or
law depending on your needs. Closed impellers and vane vanes are used.
The axial thrust is balanced by the relief disc. Two types of bearings can be used: oil-lubricated plain bearings or grease-lubricated rolling bearings.
The shaft seal may be rope or mechanical.
The drive for the highest lifting heights is double-sided (two motors per pump).
OWH pumps can be used in explosion-hazardous areas as devices
