- Nov 16, 2018 -

The pump body is one of the working parts of the water pump. Usually, the main components included in the pump body are: inlet pipe, diversion shell, check valve, pump shaft and impeller. There are two ways to fix the impeller on the shaft. Pump body castings are usually made of cast iron or cast steel, and the inner surface is required to be smooth to reduce hydraulic loss.


In the actual casting process, in order to obtain a good casting, a reasonable casting process must be selected. The casting process used for the pump body castings is clay sand. The pump body casting material conforms to the GB HT250 standard, and other basic components such as QT500-7, 450-10 gear pumps can be selected.


The processing process of the water pump Body casting mainly includes: car, boring, drilling, grinding, etc.; the surface treatment technology commonly used in this type of casting includes rust preventive oil or paint. The technical requirements for the surface of the pump body castings are: the surface of the casting is smooth, and there are no defects such as pores, blisters, cracks, etc. to reduce the strength of the parts. The size and corresponding position of the lumen flow channel are required to be correct and the surface is cleaned.
