SAP Split Case Pump

SAP Split Case Pump Description

SAP pump is a single-stage double-suction split case centrifugal pump. It is a new product developing from SA-pump on the basis of structural optimal design. The products reserve the characteristics of SA type pump of good hydraulic performance, high efficiency， as well as made a new improvement in structure comprehending the technology of West German KSB company and double-suction pump of United States IR company， make it more reasonable and reliable.

This group transfer branch water containing solid particle and liquid physics chemical properties similar to water， transferred media temperature are 0℃~80℃, suitable factory, urban, mining, power generation, water resources engineering, drainage or water supply pump.

SAP Split Case Pump Structure Feature

The shaft seal is soft packing or mechanical seal, the packing ring is installed before packing in order to prevent air from entering pump, cooling and lubricating seal chamber. While the pump operation, a small amount of high pressure water flow into the packing or mechanical seals chamber through the ladder-shaped groove on the horizontally split face of the pump cover, which function as water seal.

Main Parts of pump: Lower Casing; Upper Casing; Impeller; Shaft; Double Suction Seal Ring; Shaft Sleeve.……etc…

1, The impeller working chamber consists of pump body and the pump cover. The spiral holes for installing the vacuum gauge and pressure gauge locate at the inlet flange and the outlet flange .At the bottom of the inlet and outlet flange have drain spiral hole.(According to customer requirements using stainless steel shaft and bronze impeller)

2, The double suction seal ring is used to reduce water leakage from the pump pressure chamber flow back to the suction chamber.
1, The inlet and outlet of this type pump both below the pump axis, they are vertical to axis and in horizontal orientation. Maintain without needing to remove inlet, outlet of pipes and electric motor. Looking from driving directions SAP-type pumps are counter clockwise direction.(According to user needs can also be changed to clockwise)

3, In addition to shafts are made of quality carbon steel, the remaining main parts are made of cast iron.

4, The pump shaft is supported by single row radial ball bearings. The bearing is installed at the bearing body which fitted on both ends of the pump casing.

5, The impeller adjusted by static balancing is fixed on the shaft by the shaft sleeves and the nuts。For the axial force of the impeller, it can be balanced by symmetrical distribution of the impeller and the both sides intake water .

6, The pump is driven by the motor through the flexible coupling.(It also can be driven by diesel engine if necessary)
