The important structure of concrete delivery pump is hydraulic pump. It can be divided into domestic hydraulic pump and imported hydraulic pump according to different origin. According to the different structure forms, hydraulic pump is composed of gear pump diesel concrete mixer, vane pump and pillar-plug pump. Different forms of hydraulic pump can be used in different pressure grades.Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China.

However, because of the smaller pressure bearing and bigger impulse resistance, gear pump is often installed on the low pressure pump or used in the auxiliary oil passage system of medium and high pressure pump. concrete pump Pillar-plug pump can be classified into oblique tray pillar-plug pump and oblique axle pillar-plug pump. It is very popular because of the wider adaptive pressure rang. The main hydraulic pump of some low pressure concrete pumps adopts oblique tray pillar-plug pump, which improves the quality of the concrete pump for the high grade component configuration. The imported hydraulic pump is also oblique tray pillar-plug pump Ready-mixed concrete batching plants, which is world-class product. The domestic oblique axle pillar-plug pump is also high in quality. In fact concrete batch plant, users can judge the quality of concrete pump performance from the grade of hydraulic pump.
