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).
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.
Can PGH Series Gear Pumps be used interchangeably with other Rexroth gear pump series?
No, direct interchange is not recommended. The PGH Series has unique mounting dimensions (e.g., flange size, shaft diameter) and flow-pressure curves that differ from other series (such as the PGH4 vs. PGK Series). Interchange may lead to system mismatch or pump failure. Always refer to the Rexroth product alog for compatibility.
