Introductions:
The high pressure resistant composition vane pumps with high performance are developed for engineering machinery application,especially for walking machinery.The main fetures are as follows:
1. Adopt the structure of hydraulic balancing composition vanes,making the resistant pressure higher to maximum 21Mpa.
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 lifetime.
4. Our VQ high pressure vane pumphave characteristics of low flow pulsation, low noise emission, high working pressure, compact design, high power-weight ratio, low installation and maintenance costs, long service life etc.
5. Furthermore, the offered range is strictly inspected on numerous quality stages. We have professional QC system, and checked the products one by one, so that we can make sure the products with the high quality.
Performance parameters:
SAE 10W by hydraulic fluid △82℃(180℉)
Pump inlet △0 PSIG(14.71/Psia)
Notes: The pressure of outlet port must be higher than the one of inlet port.
