Highland High Efficiency Closed Circuit Mixer Truck Hydraulic Piston Pumps
Highland High Efficiency Closed Circuit Mixer Truck Hydraulic Piston Pumps
Closed circuit hydraulic piston pumps product introduction:
The hydraulic system of the mixer truck uses a closed circuit hydraulic transmission system. Highland hydraulic piston pump is the component that provides the power for the hydraulic system. It delivers oil with a specific flow and pressure to the system, making it the key component of the hydraulic system. Our Highland hydraulic is a professional producer, our company could provide high efficiency high performance hydraulic piston pump with matched hydraulic motors
High efficiency 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 piston pumps has swash plate structure.
3. Be Suitable for closed-loop circuit system of mixer hydraulic piston 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.
6. Closed circuit hydraulic piston pump

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.
