German Rexroth ISO9001 Certified Piston Pump for Mobile and Industrial Hydraulic Systems with Clockwise or Counterclockwise Rotation

A: Proper maintenance is crucial for longevity and reliable operation. Key practices include:

• Pre-Startup Check: Verify oil level in the tank before startup. Use the recommended grade of hydraulic fluid.
• Initial Run: After a shutdown of more than 4 hours, allow the pump to run without load for at least 5 minutes before applying pressure.
• Regular Monitoring: Consistently check operating parameters like pressure, speed, and oil temperature during work. The optimal operating oil temperature is typically between 35°C and 60°C.
• Inspection: Regularly check pipe joints and flange connections for tightness to prevent leaks and air ingress.
• Oil Cleanliness: Maintain the cleanliness of the hydraulic oil. The higher the oil cleanliness, the longer the service life of the pump.

A: Potential causes based on common issues include:

• Low Drive Speed: Ensure the motor meets the pump's required rated speed.
• Leaks in the System: Check the system for and repair any leakage points.
• Aeration/Suction Problems: Inspect the suction line for air leaks. Ensure the oil level in the tank is not too low.
• Loose Pump Casing Bolts: Prolonged operation and vibration can loosen bolts, which may need tightening to specification.

A: Some suppliers offer a 12-month quality guarantee for their hydraulic pumps and motors. Confirm specific warranty terms with your supplier at the time of purchase.

A: Yes, certain manufacturers accept OEM requests and can mark products with your brand and product codes.

A: Many suppliers provide system integration, technical support, and maintenance services. They often stock commonly used spare parts. Choose a reputable distributor for better technical support.

A: This series is widely used in various machinery, including:

• Mobile Machinery: Concrete truck mixers, cranes, and other construction equipment.
• Industrial Applications: Various stationary industrial hydraulic systems.

A: Critical safety instructions include:

• The axial piston unit must always be filled with hydraulic oil and vented before commissioning.
• The case drain line must be connected separately to the tank, below the low oil level.
• The minimum inlet pressure at port S must not fall below 0.8 bar absolute during operation.
• Use flexible connections for piping to achieve favorable noise values.
