Expert Maintenance Tips

1. Model Confirmation
PGM511 3349219285 is a Parker order number corresponding to a specific configuration. The PGM511 series offers displacements from 6–33 cc/rev. Before installation, confirm the correct displacement based on system torque requirements and verify the complete model code on the motor nameplate along with the Parker order number.

2. Rotation Direction Confirmation
The PGM511 series supports clockwise, counter-clockwise, and bi-rotational configurations. Before installation, always verify that the system flow direction matches the motor’s rotation direction—incorrect direction will result in motor failure.

3. Installation Precautions

• Thoroughly clean the SAE flange and shaft mating surfaces before installation to ensure no debris remains

• Mounting options include SAE 2-Bolt or 4-Bolt flange

• Use Parker-specified torque values for mounting bolts—avoid over-tightening which may cause distortion of the aluminum housing

• Ensure correct connection of inlet and outlet ports—PGM511 supports common inlet or separate ports for multi-section configurations

4. First Start-Up and Bleeding

• Before first start-up, must fill the motor with hydraulic oil through the inlet port—never start dry

• After start-up, run at low speed with no load for 2–3 minutes to ensure complete air evacuation from the system

• Check for abnormal noise or leakage—aluminum housing motors are particularly sensitive to cavitation

5. Fluid and Filtration

• Use high-quality anti-wear hydraulic oil compliant with DIN 51524 standards

• Fluid cleanliness requirement: ISO 4406 Class 19/17/13

• Maintain operating temperature within -40℃ to 80℃

• Regularly replace return line filters to prevent contaminants from entering the motor

6. Periodic Maintenance

• Check mounting bolt torque every 1,000 operating hours

• Regularly monitor system operating pressure—not to exceed 250 bar rated pressure

• Regularly inspect shaft seals to prevent leakage

• If torque output decreases, noise levels increase abnormally, or system temperature rises excessively, inspect and replace worn components promptly

Expert Maintenance Tips

1. Model Confirmation
PGP620 S0330CD1H3NT3B1LZAL offers 33 cc/rev displacement. The PGP620 series offers displacements from 16–52 cc/rev. Before installation, confirm the correct displacement based on system flow requirements and verify the complete model code on the pump nameplate along with the Parker order number.

2. Rotation Direction Confirmation
The PGP620 series supports clockwise, counter-clockwise, and bi-rotational configurations.
