20 hp 175-400cc Radial Piston Hydraulic Motor, 20MPa

Buy radial piston hydraulic motor from reliable manufacturer. Working power 17/20/21 hp (13/15/16kW), rated pressure 1740~2320 psi, rated torque 424~667N.m. The radial piston engine has high efficiency. The higher the torque, the lower the speed.

Specification

Features

• The radial piston hydraulic motor is a large torque motor with crankshaft and rod.
• The shell of radial piston hydraulic motor is extruded and nitrided, which is resistant to wear, fatigue and high temperature.
• The plunger body is nitrided, added with specially developed piston rings, and good wear resistance.
• Oil seal of the radial piston hydraulic motor uses skeleton oil seals, high temperature resistance, high pressure, and it is not easy to leakage.
• Applications of the radial piston hydraulic motor include injection molding machines, ship deck machinery, construction machinery, lifting vehicles, heavy metallurgical machinery, petroleum mine machinery, light equipment, board, drilling machines and other hydraulic transmission systems and equipment, etc.

Tips: Precautions for using radial piston hydraulic motor

1. Radial piston hydraulic motor filtration: the recommended filtration precision for normal industrial use is 25 μm, and 75μm is permitted for low pressure, low speed or intervallic setting.
2. Oil viscosity: the optimum performance could only be obtainedunder proper oil viscosity between 15-1000cst.
3. Before the first start-up of radial piston hydraulic motor, it must fill hydraulic oil in the hydraulic motor body, to avoid the damage.
4. Radial piston hydraulic motor leakage: drain port should be connected separately to the tank. Normally the maximum pressure for the motor body is0.1Mpa, and it could also be improved to bear 3-5Mpa, to meet special requirements.
5. The top line of the drain pipe should be higher than that of the radial piston hydraulic motor body, in case empting oil storage.
6. Radial piston hydraulic installation: motor can be installed in any position with rigid support. When installing, shafts of the motor and its transmission should be concentric.
7. Cleanness: strictly maintain the cleanness of the oil port, and keep any solid particles away.
8. Radial piston hydraulic motor could not work as a pump.
