Overview

Two standards, one fluid bench.

The Neometrix Test Rig for Hydraulic Fluid is engineered to evaluate the anti-wear properties and oxidation behaviour of hydraulic fluids under strictly controlled, reproducible conditions.

The rig employs two industry-standard test pumps as its load elements: a Vickers 35VQ25A-11*20 rotary vane pump for ASTM D6973-2014 testing, and a bent-axis axial piston pump (A2F10) for JCMAS P 045 testing. By analysing the mass loss of the wear inserts — cam ring and vanes — and monitoring fluid condition after the run, the bench quantifies exactly how well a fluid resists wear and oxidation.

A rotary vane pump generates the required test pressure, while a pressure-relief valve on the bent-axis circuit creates high-temperature stress in the presence of air and a copper catalyst, accelerating aging inside a realistic hydraulic component rather than a glass beaker. As a lubricant aging machine it therefore reproduces genuine in-service degradation mechanisms.

Real pumps. Real pressure. Real aging — measured to 0.1 seconds.

All design and safety features comply with the European Machinery Directive 2006/42/EC (or equivalent Indian standards), and fluid cleanliness is held at NAS 1638 Class 6 or better across ISO VG 32, 46 and 68 grades — making this high-pressure hydraulic tester equally suited to batch-release QC, formulation R&D and third-party certification work.

About the machine

The Test Rig for Hydraulic Fluid is engineered to evaluate the anti-wear properties and oxidation (aging) behaviour of hydraulic fluids under strictly controlled, reproducible conditions. It employs two industry-standard test pumps as the load elements:

Vane pump (Vickers 35VQ25A-11*20) for ASTM D6973-2014 testing.
Bent-axis axial piston pump (A2F10) for JCMAS P 045 testing.

By analysing mass loss of the wear inserts — cam ring and vanes — and monitoring fluid condition post-test, the rig quantifies how well a fluid resists wear and oxidation. A rotary vane pump generates the required test pressure, and a pressure-relief valve on the bent-axis circuit creates high-temperature stresses in the presence of air and a copper catalyst, accelerating aging inside a realistic hydraulic component. All design and safety features comply with the European Machinery Directive 2006/42/EC (or equivalent Indian standards).
