S single stage double suction centrifugal pumps are late-model energy-saving horizontally split pumps newly developed by us on the base of the old style double suction pumps at home and abroad．They are used to handle clean water or other liquids similar to water in physical and chemical properties．medium temperature not exceeding 80 ℃．This series of pumps are applicable for factories，mines，urban water supply and drainage，power stations，farmland irrigation and drainage，and other water conservancy projects．

The instruction of the structure:

　　The inlet and outlet of this type of pumps are below the axial lead of the water pump and are vertical with the axis line. When repair and examination, there is no need to disassemble the inlet, outlet pipe and the motor. Seeing from the direction of driving, the pump is circumrotating clockwise. (We can change it into counter-clockwise).
　　The main components of the pump are: pump body; pump cover, impeller, axis, balanced suction seal loop, axial bush, and etc.
　　The pump body and pump cover consists of the working room of the impeller. On the water inlet flange and outlet flange, there is pipe tap for installing the vacuum meter and pressure meter. Under the inlet flange and outlet flange, there is pipe tap for pouring the water.
　　The impeller after quiet balance checkout is fixed on the axis by axial bush and the axial bush nuts on the both sides. Axile nuts can adjust the axial position.
　　The pump axis is supported by two single low annular ball bearings. The bearing is in the bearing body, installed on the two ends of the pump body. Lubricate it by butter.Balanced suction seal loop is used to reduce the water in pressure room of water pump leak to water jet room.
The pump is directly driving by flexible shaft coupling. It also can be drove by gas engine.
The axis seal is flexible sealant (We can adopt mechanical seal structure).
