Boasting high pressure, low noise and energy saving technology in a compact package, the Nachi PZH is a variable-displacement axial-piston pump, designed to take on all demanding applications.

Pump Specifications:

  • Circuit Type: Open loop
  • Fluid Type: Hydraulic fluid
  • Displacement: 72cc/rev
  • Max Continuous Pressure: 350 Bar
  • Peak intermittent Pressure: 400 Bar
  • Operating Speed: 500 - 2000 RPM

The PZH manages to save energy and reduce operating noise by utilising low friction engineering on all sliding surfaces. Pressure pulsation is also reduced, therefore providing a smoother pressure flow within the hydraulic circuit (which is incredibly important in any extrusion/forming process to reduce ripple in the finished manufactured part.)

Currently, there are 2 different displacements of 45 and 72cc/rev available with more units to follow in 2021/2022.


For customers looking to specify a high performance a reliable 70cc/rev pressure compensated, axial piston pump capable of 350 bar, the PZH-3B makes a first-class substitute to the following pump models in the same pressure and flow class:

  • Kawasaki K3VL71
  • Rexroth A4VSO71
  • Yuken A3HG71

Standard Features:

  • Pressure compensated or horsepower limiting compensator control
  • Pressure adjustment from 20-350 bar
  • 4 Bolt mounting flange
  • SAE heavy duty shaft

Product Options:

  • Thru-shaft for driving multiple pumps from a single motor
  • Foot or flange mounting options
  • 2 x outlet port orientation options

Zeus Hydratech fully supports the Nachi PZH pump product line and is the only valid source for OEM parts in the South of the UK. All Nachi repairs are machined and tested per our original factory specifications.
