main pump assembly

Gear Pump:

Gear pumps work by closed movement in the form of two meshing gears rotating. The gear pump is driven by gears to provide power, and the gear pump is a quantitative pump, which is mostly used for low-precision medium and low pressure control.

Its main features are: simple structure, convenient manufacture, low cost, low price, small volume, light weight, good self-priming performance, insensitivity to oil pollution and reliable operation.

Its main disadvantages are: large flow and pressure pulsation, high noise, and unadjustable displacement.

It is widely used in various low-voltage systems. Gear pumps have the lowest requirements for oil. At the earliest, they were generally used in low-pressure systems (pilot pumps) because of their low pressure. Now, the pressure of gear pumps can reach about 25MPA, which is often used in machinery with low pressure requirements. The oil pulsation is large and cannot be variable. The advantage is that the self-priming performance is good.
