FAQ for PGH Series Gear Pumps

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

The PGH Series stands out for its high pressure stability (supporting working pressures up to 250 bar for most models), compact structural design (saving installation space in hydraulic systems), and low noise operation (noise levels as low as 65 dB under rated conditions), making it ideal for continuous-duty industrial scenarios.

2. What precautions should be taken during the installation of PGH Series Gear Pumps?

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.
