FAQ for PGH Series Gear Pumps

1. What core advantages make the PGH Series Gear Pumps suitable for industrial use?

PGH Rexroth Gear Pumps are widely used in industrial machinery (such as plastic injection molding machines, hydraulic presses) and mobile equipment (including construction machinery like small excavators, and agricultural machinery such as tractors) due to their stable pressure output and compact structure.

2. How to troubleshoot if the PGH Rexroth Gear Pump has insufficient pressure?

First, check if the inlet oil filter is clogged and clean or replace it if necessary; second, inspect the sealing parts of the pump (like O-rings) for damage and replace faulty seals; finally, verify if the relief valve matching the pump is stuck and perform maintenance on the valve.

3. What type of hydraulic oil is suitable for PGH Rexroth Gear Pumps?

It is recommended to use hydraulic oil that meets ISO VG 46 or ISO VG 68 specifications. The oil should have good anti-wear and anti-oxidation properties, and the oil temperature during operation should be controlled between -10°C and 80°C to avoid affecting pump performance.

4. How often should maintenance be performed on PGH Rexroth Gear Pumps?

For general industrial applications, routine inspection (checking oil level, temperature, and leakage) should be conducted monthly; oil change and filter replacement are recommended every 6 months or after 2000 hours of operation; a comprehensive disassembly and inspection of the pump should be carried out every 2-3 years.

5. Can PGH Rexroth Gear Pumps be used in high-temperature environments for a long time?

No. The maximum allowable long-term operating temperature of PGH Rexroth Gear Pumps is 80°C. Prolonged use in environments exceeding this temperature will accelerate the aging of internal seals and bearings, significantly reducing the pump's service life and even causing sudden failures.
