Product Details

Jian Highland hydraulic pump seal kits

Concrete mix truck hydraulic pump

Product Description:

By introducing Heavy Series20sereis static hydraulic transmission from America,

we can provide axial hydraulic pump and hydraulic motor assembly and hydraulic system with high quality,

high performance parameters.Pump is the variable one that is with Charge Pump, and the motor the quantitative,or variable one with valve assembly.

The continuous working pressure under the maximum speed 21-23 heavy-duty hydraulic pump and the sealed static hydraulic gear system made up of hydraulic motor series is 21Mpa.

The system’s maximum operating pressure is 35Mpa and the system’s minimum pressure is 0.9 Mpa higher than the shell whose maximum pressure is 0.28 Mpa.

Charging Pump‘s pressure is 1.31-1.45 Mpa higher than the shell, fill the motor oil pressure relief valve set point higher than the shell 1.10-1.24 Mpa, and the maximum oil temperature is 80 °C.

(1).Mainly used on the Concrete mixer trucks,Paver,road roller,continous soil mixing machine,concrete pump and pharmaceutical machinery,ship.

Series 20 Axial Piston Variable Displacement Pump Features:

1. Series 20 Axial Piston Variable Displacement Pumps are well engineered and easy to handle.

2. The full-length shaft with a highly efficient tapered roller bearing arrangement offers a high loading capacity for external radical forces.

3. The pumps can be connected with other additional pumps.

4. The hydro-mechanical servo displacement control maintains the selected swash plate position and hence pumps displacement.

5. Upon release of the control handle, the swash plate automatically returns to zero position and the flow reduces to zero.

6. High case pressures can be achieved without leakage even at the lowest temperatures by using suitable shaft seals.

7. The servo valve arrangement offers the facility to incorporate function regulators and remote control systems.

8. Axial piston units are designed for easy servicing. Complete dismantling and reassembly can be carried out with standard hand tools, and all components or sub-assemblies are replaceable.
