Highland PV23 Closed Circuit Mixer Hydraulic Piston Pumps For Sale
Closed circuit hydraulic piston pumps product introduction:
The hydraulic piston pump of the mixer truck consist of closed
circuit hydraulic transmission system. The hydraulic piston pump is the power component of the hydraulic
system. Its function is to supply the oil with a certain flow and
pressure to the system, so it is also the core component of the
hydraulic system.
PV23 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.
