Transit mixer PV21 hydraulic pumps substitute imported products
Transit mixer PV21 hydraulic pumps basic introduction:
Transit mixer hydraulic pump is to convert the mechanical energy of power machine into the pressure energy of liquid. The output flow can be adjusted according to need is called variable pump, the flow can not be adjusted is called fixed pump. Our mixer hydraulic pump is variable displacement piston pump.
PV21hydraulic pumps performance and characteristics:
Series 20 axial piston variable displacement pumps are swash plate design with variable displacement, and are intended for closed circuit applications.
The flow rate is proportional to the piston pump input speed and displacement.
The latter is infinitely adjustable between zero and maximum displacement.
Flow direction is reversed by tilting the swash plate to the opposite side of the neutral (zero displacement) position.

Hydraulic oil notice of hydraulic pumps:
Hydraulic system pollution will affect the normal operation of the mixer truck 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.
