Highland High pressure axial variable piston pump usages:
1. Maximize performance, efficiency, and design
Highland hydraulic pumps are perfect fit for your concrete mixer
trucks. Also, it fits hundreds of applications.
2. Construction: Durable, robust design meets the demands of harsh
work conditions for applications in construction machinery, such as
mixer truck. forestry, and agriculture machines.
3. Wide range of displacements: Offering a range of pumps with
30-130 cm² per round. Our hydraulic pumps are flexible enough to
fit all kinds of applications.
4. High pressure capability: keep high performance of working
conditions at 420 Bar instantaneous high pressure situation.
5. Widely application: Concrete mixer, bulldozer, and combine
harvesters and silage harvester etc construction and agricultural
machinery.

Hydraulic oil notice of axial piston motors:
Hydraulic system pollution will affect the normal operation of the
concrete mixer at any time, and affect the service life of
hydraulic pumps and hydraulic motors, serious damage to the pump
and 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.
