Single-stage double-suction horizontal split casing centrifugal pump;split casing centrifugal pump;
General introduction:
Type SAP pump is single-stage double-suction centrifugal pump with horizontal split casing. It is provided for delivering clear water without solid particles or other liquid which is physically and chemically similar to clear water. The temperature of the liquid is 0°C~80°C. It is widely used in fields of factories, mines, municipal wate supply, power stations, agriculture irrigation and water conservancy. Permissible maximum inlet pressure is 0.6Mpa.
PERFORMANCE RANGE
Capacity Q : 108~10800m3/h
Head H : 8.5~140m

58 Head at design point (m)
A A,B,C separately represents outer diameter of impeller has been cut for the first, the second and the third time.The inlet and the outlet of the pump are under the axis and their centerline is perpendicular to the axis. It is unnecessary to disturb the inlet piping, the outlet piping and the motor while inspection.
The main parts of the pump consist of casing, pump cover, impeller, shaft, shaft sleeve and double suction wearing ring, etc. Impeller, shaft sleeve and double-suction wearing ring are consumable parts.
The impeller is fixed on the shaft with the shaft sleeves and the sleeve nuts.Its axial displacement will be adjusted by the sleeve nut.The thrust of the impeller will be balanced with the help of symmetric vanes.
The double-suction wearing ring is to reduce leakage from pressure water house to suction house.
The shaft seal is either packing seal or mechanical seal.The bearing lubricated oil has dry-oil and dilute oil.When the inlet diameter of the pump is less than 800mm, the bearing gets lubricated with dry-oil. When the inlet diameter is more than 800mm,the bearing gets lubricated with dilute oil.
The pump is connected with the motor through flexible coupling.CONSTRUCTION The rotation of the pump rotor is clockwise looking from the driver to the pump, i.e. the inlet is on the right and the outlet is on the left.It is also counter clockwise according to customers' requirement.
