Product Description
PGH Series Internal Gear Pumps
Product Description
The PGH series is a fixed-displacement, internal gear pump with leakage gap compensation, designed for high efficiency and low noise operation. It is widely used in industrial hydraulic systems requiring precise fluid delivery under high pressure (up to 350 bar) and variable viscosity conditions.
Key Features
- High Efficiency: Gap compensation technology ensures optimal performance even at low speeds or with low-viscosity fluids. Low noise and minimal flow pulsation due to optimized gear geometry.
- Versatile Performance: Suitable for a wide range of viscosities (12-20,000 mm²/s) and speeds (200-3,000 rpm depending on model). Compatible with HFC fluids (when equipped with W-seal).
- Robust Design: Components include pump body, gear ring, pinion shaft, sliding bearings, axial plates, and sealing elements. Axial compensation via pressure fields ensures minimal internal leakage.
- Modularity: All sizes (PGH2-PGH5) and displacements can be freely combined or paired with other pumps.
