The HGP-3A siries gear pump is a power element in the hydraulic system. The HGP-3A series high pressure gear pump adopt high precision toothed gear and high-strength aluminum alloy shell, make it get many advantages like simple construction,light weight, efficient, low noise, reliable used etc. And it widely used in the hydraulic system in automobile, engineering machnery, jack-up transportation machinery, mining machinery and agricultural machinery etc.

It can form with low pressure large flow vane pump into high and low pump group, so as to utilize the main energy rationally and save the cost.
