Highland PV22 69.8ml/r Displacement Concrete Mixer Axial Piston Pump
Axial piston pump main function:
Mixer hydraulic pumps i.e. hydraulic axial piston pumps change the angle of piston slide to change the pump displacement and change the tendency of hydraulic pump plunger slide plate to change the flow to achieve positive and reverse, and then change the speed of the mixer tank by adjusting the hydraulic motor throttle.
PV22 axial piston pump performance and characteristics:
1. High efficiency, high pressure, big displacement design meets the demands of harsh work conditions for mixer truck.
2. PV22 hydraulic piston pump has swash plate structure.
3. PV22 hydraulic pump be suitable for closed-loop circuit system of mixer truck.
4. Hydraulic piston pumps have manual servo and hydraulic variable control mode.
5. Mixer hydraulic pumps are variable displacement pumps with a charging oil pump.

Mixer piston pump advantages:
1. High working pressure: due to easy processing of plunger and cylinder hole, dimensional accuracy and surface quality can meet high requirements, so high precision, small oil leakage, high volume efficiency, high working pressure can be achieved.
2. Large flow range.
3. change the stroke of the plunger can change the flow, easy to make a variety of variable type.
