China Rexroth Dfr Variable Displacement Piston Pump Swash Plate, Find details about China Hydraulic Pump, Piston Pump from Rexroth Dfr Variable Displacement Piston Pump Swash Plate
Specially designed for open circuit hydraulic drive, remote control control.
The flow of the pump is proportional to the speed and displacement of the pump, and the displacement can be adjusted steplessly by adjusting its swash plate inclination.
Low noise, long life, modular design.
Through-shaft structure can form a combined pump, and the installation position is optional.
1. Five-piston structure with eccentric shaft and low excitation frequency, has the characteristics of low noise; |
2. Large starting torque, good stability at low speed; |
3. Plane compensation oil distributor with good reliability and no leakage; piston and plunger sleeve are sealed by a sealing ring, which has high volumetric efficiency; |
4. Roller supports are provided between crankshaft and connecting rod, has high mechanical efficiency; |
5. Rotation direction is reversible, and output shaft is allowed to bear radial and axial external forces; |
6. High power quality ratio, small volume and weight. |
7. Noise is less than 80 dbs. |
