Frequently Asked Questions

Selection

Select a viscosity grade (e.g., VG 46, VG 68) so that the viscosity at the operating temperature (typically tank temperature in open circuits) falls within the optimal range. Generally, opting for a higher viscosity grade is advised.

Fluid Cleanliness Requirements

To ensure reliable operation and long service life, the oil cleanliness should be at least NAS 1638 Class 9 or ISO/DIS 4406 18/15.

Pump Overheating Causes

Internal Leakage: Excessive internal leakage within the pump components converts hydraulic energy to heat.
Mechanical Friction: Dry or semi-dry friction due to worn parts or inadequate lubrication generates heat.
Fluid Friction: Inadequate tank capacity or cooling, causing the system to overheat.
Clogged Return Line Filter: A blocked return filter creates high backpressure, leading to increased temperature.
Low Oil Level: Insufficient oil in the reservoir reduces cooling capacity.

Maintenance & Troubleshooting

Daily/Regular Maintenance

Keep the pump exterior clean from dust and oil.
Check oil levels before start-up and during operation.
Listen for abnormal noises during operation, which may indicate internal issues like part wear or looseness.
Regularly record operating parameters like pressure, flow, and temperature to monitor health.
Change fluid filters periodically (e.g., every 1000 hours or as per conditions).
Check and replace worn or aged seals.
Follow lubrication requirements for various points.
Inspect the coupling for looseness or wear.

Insufficient Flow Causes

Insufficient Inflow: Caused by high suction line resistance, low oil level, excessive pump speed, or a clogged inlet strainer/suction line.
Excessive Leakage: Worn internal parts (pistons, cylinder block, port plate) leading to high internal leakage.
Swash Plate Angle: The swash plate angle might be set too small, minimizing displacement.
