PGH Series Gear Pumps - Industrial High Pressure Quantitative Hydraulic Pumps
Product Overview
The PGH Series Gear Pumps from Rexroth are precision-engineered hydraulic pumps designed for high-pressure industrial appliions. German manufactured for reliability and performance.
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?
Ensure the pump's rotational direction matches the system's requirements (reverse rotation can cause internal component damage).
Keep the suction line length within 1 meter and avoid sharp bends to prevent insufficient oil suction.
Tighten the flange bolts to the torque specified in the manual (typically 18-22 N*m for standard models) to avoid oil leakage or housing deformation.
3. How to resolve abnormal noise from a PGH Series Gear Pump during operation?
First, check if the hydraulic oil level is too low (topping up to the standard level if needed); second, inspect for air bubbles in the oil circuit (bleeding the system to remove air); finally, check if the bearing is worn (replacing the bearing if there is excessive radial play).
4. What is the recommended hydraulic oil cleanliness level for PGH Series Gear Pumps?
To avoid clogging internal oil passages or accelerating wear, the hydraulic oil must meet a NAS 8级 (NAS Class 8) cleanliness level. Additionally, use oil with anti-foaming and anti-rust additives to extend the pump's service life.
