4. Installation Instructions

4.1 Installation Preparation

Inspect the pump for any damage during transportation (e.g., cracks, oil leaks, loose components). Do not install or operate a damaged pump.
Ensure the installation area is clean, dry, and well-ventilated, with sufficient space for maintenance and operation.
Prepare the mounting surface: it must be flat, smooth, and free of debris. The surface roughness should meet the manufacturer’s requirements to ensure proper sealing and load distribution.
Check that the hydraulic fluid is clean and meets the specified grade. Contaminated fluid can cause severe damage to the pump’s internal components.

4.2 Mounting the Pump

Align the pump’s mounting flange with the mounting surface and secure it using the specified bolts. Tighten the bolts evenly in a crisscross pattern to the recommended torque (refer to the torque table in Appendix A).
Ensure the pump shaft is aligned with the drive shaft (e.g., motor shaft) within the allowable misalignment range (max 0.1 mm axial misalignment, max 0.2 mm radial misalignment). Misalignment exceeding this range will cause excessive wear on bearings and seals.
Connect the inlet and outlet pipelines to the pump’s ports. Use appropriate fittings and ensure tight connections to prevent oil leaks. The inlet pipeline should be as short and straight as possible to minimize pressure loss.
Install a filter in the inlet pipeline to prevent contaminants from entering the pump. The filter’s filtration rating should be at least 10 μm.

4.3 Pre-Installation Check

After installation, check the following items before starting the pump:

All bolts and connections are tight and secure.
The pump shaft rotates freely without obstruction or abnormal noise when turned manually.
The hydraulic fluid level in the system is within the normal range.
The direction of rotation of the drive motor matches the pump’s specified rotation direction (clockwise, as indicated by the arrow on the pump housing).

5. Operation Instructions

5.1 Start-Up Procedure

Prime the pump to remove air from the hydraulic system: open the vent valve (if equipped) and start the drive motor at low speed (500-800 r/min) until hydraulic fluid flows out of the vent valve without air bubbles. Close the vent valve once priming is complete.
Gradually increase the motor speed to the rated speed (1800 r/min) and run the pump under no-load conditions for 5-10 minutes. Check for oil leaks, abnormal noise, and overheating.
Slowly adjust the system pressure to the required working pressure. Do not exceed the pump’s maximum pressure rating.
Monitor the pump’s operation parameters (oil temperature, pressure, noise) during the initial run. Ensure all parameters are within the specified range.

5.2 Normal Operation

Maintain the hydraulic fluid temperature between -25°C and 90°C. If the temperature exceeds 90°C, take cooling measures (e.g., install a cooler) to prevent damage to the pump and fluid.
Monitor the system pressure regularly. Do not operate the pump at pressures exceeding the maximum rating for extended periods, as this will reduce service life.
Avoid sudden changes in pressure or flow, as this can cause hydraulic shock and damage to the pump’s internal components.
Check the pump for oil leaks during operation. If a leak is detected, stop the pump immediately, identify the cause, and repair it.

5.3 Shutdown Procedure

Reduce the system pressure to zero by adjusting the control valve.
Stop the drive motor.
Close the main power supply and shut off the hydraulic fluid supply (if applicable).
Drain the hydraulic fluid from the pump and system if the pump will not be used for an extended period (more than 30 days).

6. Maintenance and Servicing

6.1 Routine Maintenance Schedule

Maintenance Item	Frequency	Maintenance Content
Check hydraulic fluid level and cleanliness	Daily	Top up fluid if necessary; check for contamination (e.g., dirt, water)
Inspect for oil leaks	Daily	Check pump housing, pipelines, and connections for leaks
Clean inlet filter	Every 100 hours	Remove and clean the filter element; replace if damaged
Change hydraulic fluid	Every 2000 hours or 6 months (whichever comes first)	Drain old fluid, flush the system, and refill with new fluid of the specified grade
Inspect shaft seal	Every 500 hours	Check for oil seepage; replace the seal if worn or damaged
Comprehensive inspection	Every 4000 hours	Disassemble the pump (by qualified personnel) and inspect internal components (cylinder barrel, valve plate, swashplate, bearings) for wear; replace worn parts as needed

6.2 Maintenance Notes

Always shut off the power supply and relieve system pressure before performing any maintenance or servicing.
Use only genuine VICKERS replacement parts. Non-genuine parts may not meet the pump’s specifications and can cause premature failure.
Keep all maintenance tools and the work area clean to prevent contamination of the hydraulic system.
After maintenance, reassemble the pump correctly and perform a no-load test before returning it to normal operation.

Oil leaks	1. Loose connections; 2. Worn shaft seal or O-rings; 3. Cracked pump housing	1. Tighten the connections; 2. Replace the seal or O-rings; 3. Replace the pump housing if cracked

8. Safety Precautions

The pump operates at high pressure. Do not touch any high-pressure components during operation, as this may cause serious injury.
Only qualified personnel should install, operate, and maintain the pump. Unauthorized operation may result in equipment damage or personal injury.
Always wear appropriate personal protective equipment (PPE) when working with the pump, including safety glasses, gloves, and protective clothing.
Do not modify the pump’s structure or components without the manufacturer’s approval. Modifications may affect the pump’s performance and safety.
In case of emergency (e.g., severe leaks, overheating, abnormal noise), stop the pump immediately and shut off the power supply.
