详细介绍

The series high pressure resistant composition vane pumps with high performance are developed for engineering machinery application,especially for walking machinery. The main features are as follows:

1. Adopt the structure of hydraulic balancing composition vans, making the resistant pressure higher to maximum 21 Mpa.

2. Adopt the structure of floating side plate supporting with its function of automatic tolerance compensation, which helps to get pressure balance and high performance under high rotation speed and high pressure.

3. Adopt bimetal flexible material for side plates, which dramatically improves the engagement performance of the gears and thus makes the pump working better and longer.
