Hydraut PQ series variable displacement axial piston pump — **Hydraut PQ**Swash plate axial piston pump, 250 bar rated, 280 bar peak.

The Hydraut PQ series axial piston pumps represent the optimal solution for advanced automation needs. Carefully designed and precise, they are characterized by an array of distinctive qualities:

Multiple configurations: their structure allows easy adaptation for multiple configurations, enhancing flexibility of use.
Load-sensing version: available in a load-sensing version to ensure better control and a more efficient response to load variations.
Durability: with a nominal pressure of 250 bar and a maximum pressure of 280 bar, these pumps are ready to withstand the most demanding stresses.

Technical data by model

The PQ series is a variable displacement axial piston pump with a swash plate design. Six displacements in four sizes; flow, weight and pressure setting ranges change.

Frequently asked questions

What are the displacements of the Hydraut PQ series?

Six models: PQ15 (15 cm³/rev), PQ23 (23), PQ38 (37.8), PQ42 (42), PQ50 (51.5) and PQ70 (69.7). Rated pressure 250 bar, maximum 280 bar.

What is the difference between the A, G and HL controls?

A is the standard pressure control. G is the remotely adjustable pressure control. HL is the load sensing control, with pressure margins of 7, 14 or 21 bar (variants A, B, C). Other controls are available on request.

Can I have the pump with a through shaft or as a multiple pump?

Yes, the series is prepared for multiple configurations. The catalogue provides power take-off flanges on request, from Ø50.8 mm (SAE AA) to Ø127 mm. Tell us the configuration you need.

How do I find the right code or replace an existing pump?

Send us the code of the pump to replace or the nameplate data: displacement, pressure, control, ports and shaft. A technician replies within 24 working hours.

Are PQ pumps available in stock?

Models from PQ-15 to PQ-70 are usually available. For up-to-date stock, registered customers can check on Fluid-Hub.net.

Can't find the code you need?Control, displacement, ports, shaft and power take-off can be combined in many ways. Write to us with the code or the system data: an Interfluid technician replies within 24 working hours.
