Highland variable hydraulic piston pumps for concrete mixer truck
Variable hydraulic piston pumps product introduction:
The hydraulic piston pump of the mixer truck consist of closed hydraulic transmission system. The engine power in mixer is transferred to the hydraulic pump by the transmission shaft, and the hydraulic pump transmits the hydraulic energy to the hydraulic motor, which drives the reducer to drive the mixing tank, so as to realize the function of loading, mixing and unloading.
Our hydraulic piston pumps are axial flow variable displacement.
Hydraulic piston pumps main features:
1. High efficiency, durable, robust design meets the demands of harsh work conditions for applications in mixer truck.
2. Mixer truck hydraulic pumps has swash plate structure.
3. Be Suitable for closed-loop circuit system of mixer hydraulic pump.
4. Hydraulic piston pumps have manual servo and hydraulic variable control mode.
5. Hydraulic pumps are variable displacement pumps with a charging oil pump.

Company service of variable piston pumps:
Quick response within 24 hours.
Provide technical guidance.
Help customer solve hydraulic confusion.
Excellent after-sale service.
100% factory testing before shipment.
Preferential factory price, short delivery time.
Hydraulic oil notice of hydraulic piston pumps:
Hydraulic system pollution will affect the normal operation of
concrete mixer truck at any time, and affect the service life
of hydraulic piston pumps, serious damage to hydraulic pump motor,
so it is very important for the hydraulic system.
Oil change and oil filter replacement:
1. 500 working hours for first run.
2. Replace every 1500 working hours from now on, but at least once
a year.
3. Note: When changing oil, replace hydraulic filter element at the
same time.
