Factory Wholesale 42Mpa High Pressure Concrete Mixer Axial Flow Hydraulic Piston Pump
Concrete mixer hydraulic piston pump main function:
The hydraulic system of a concrete mixer consists of three main components: a hydraulic piston pump, a hydraulic piston motor and a reducer unit. The hydraulic pump converts the mechanical energy from the engine into hydraulic energy, which is then transmitted to the hydraulic motor. The hydraulic motor drives the reducer unit, which reduces the speed and increases the torque of the rotation. The reducer unit then rotates the tank, which mixes the concrete inside.
Higland hydraulic is professional manufacturer product high pressure 42Mpa concrete mixer axial flow hydraulic piston pumps with factory direct sale and wholesale price, high quality and high performance, welcome your inquiry.
Axial flow hydraulic piston pump performance and characteristics:
1. High efficiency, high pressure, big displacement design meets the demands of harsh work conditions for mixer truck.
2. Hydraulic piston pump has swash plate structure.
3. 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.

42Mpa high pressure piston pump advantages:
1. 42Mpa 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.
