Material No: 
Overview

PGH series internal gear pumps feature a gap-compensated design and constant displacement. A hydrodynamically mounted pinion shaft drives the internal gear, with radial compensation elements ensuring smooth separation between suction and pressure zones for reliable, efficient operation.

Features
  • Fixed displacement for consistent performance
  • Exceptionally low operating noise
  • Minimal flow pulsation
  • High efficiency at low speeds and viscosities, thanks to gap compensation
  • Suitable for a broad range of viscosities and speeds
  • Flexible frame and size combinations
  • Compatible with internal gear pumps, vane pumps, and axial piston pumps
