>>diesel engine water pump suction double acting high pressure hydrotest information
Model QS pump is a single-stage double-suction horizontal split centrifugal pump and used to transport pure water and the liquid of both
physical and chemical nature similar to those of water, the maximum temperature of which must
not be over 125℃ , suitable for water supply and drainage in factories, mines, cities and electric
stations, waterlogged land drainage and irrigation of farming land and carious hydraulic projects.
Both inlet and outlet of this pump are placed under the axial line, horizontally and vertical to the
axial line, the pump casing is opened in the middle, so it is unneccessary to remove the water inlet
and outlet pipelines and motor(or other prime movers). The pump moves CW viewing from the
clutch to it. The pump moving CCW can also be made.
>>diesel engine water pump suction double acting high pressure hydrotest main parts
The main parts of the pump are: pump casing, pump cover , impeller , shaft, dual-suction seal ring, muff, bearing etc.
The impeller is static-balance calibrated, fixed with the muff and the muff nuts in both sides and its axial position can
be adjusted via the nuts and axial force gets balanced by means of the symmetrical arrangement
of its blades.

The pump shaft is supported by two single-column centripetal ball bearings, which are mounted inside of the bearing body on both ends of
the pump and lubricated with grease. The dual-suction seal ring is used to reduce the leak at the impeller.
The flexible couplings connect the pump with the motor directly. For pumps driven by belt, there
must be an intermediate bracket fitted for supporting the belt pulley.
