Centrifugal pump selection of four major considerations

Centrifugal pump series is the same type of structure and use of the pump, such as ISG pipeline centrifugal pump, IS-type water pump, S-type double suction centrifugal pump.

Yongjia Quan in the choice of centrifugal pump series of products need to pay attention to the following 4 points:

First, according to the actual installation conditions to choose a vertical or horizontal pump pump.

Second, according to the size of the flow selection of single suction pump or double suction pump, or small flow centrifugal pump.

Third, according to the level of head first with single-stage pump, multi-stage pump or high-speed centrifugal pump and other pumps.

Fourth, according to the media with the characteristics of selected pumps, such as corrosion-resistant pump, water pump, impurity pump. If the medium is highly toxic, precious metals, or radioactive substances are not allowed to leak, should choose non-leaking pump. Such as shielded pumps, magnetic pumps, and the like. Or a double-face mechanical seal with a leaking liquid collection and leakage alarm device. If the medium is liquefied and so easy to volatile liquid should choose low cavitation surplus pump, such as cylindrical pump.

After the above can be determined according to various types of pumps in different series of pump characteristics and conditions of the plant, select the appropriate pump series and production plant. Finally, according to the characteristics of the device and pump process parameters, decide which type of manufacturing, testing standards. Such as the requirements of the higher API610 optional standard, the general requirements, optional GB5656 (ISO5199) or ANSI B73.1 M standard.
