End-Suctin Centrifugal Pump——SXA

SXA series single stage end-suction centrifugal pumps is based on new technology, the pump is successfully design based on long-term technology accumulation and on the experience of domestic and overseas advanced technology.
The casing is end suction and radial discharge design. Its discharge centerline and shaft are in the same vertical plane.
The casing is directly fixed on the base-plate.
The pump is back-pull-out design, which allows disassembling the casing cover and rotary components without removing the pipe. The mounting frame is supplied with two ball bearings, lubricate by grease or engine oil.
The suction and discharge flange, the casing and pump foot are all cast to a whole.
The pump comply with DIN24255 and BS EN733 standard, they have high interchangeability.    

Application    

Water supply and transfer in municipal and industrial applications.

Q_opt——Pump operating point    

Pressure Limits

Standard hydrostatic test pressure
The standard test pressure is calculated as follows:
1.2 x (H_Q=0+ H_Inlet) or 1.5 x (H_Q=Q_opt+ H_Inlet) , The higher value is to be used
H_Q=0 ——Head at close the valve
H_Inlet——Pump max. inlet pressure
Q_opt——Pump operating point
