Mechanical Oil Pump Air Test

The demands for a safe, clean production environment may require the use of air as a test medium, instead of oil. However, correlating the test results using air (a compressible fluid) to performance data using oil is particularly difficult. Furthermore, variable displacement pumps, with solenoid or pressure actuated eccentric rings, are particularly challenging to validate using air.

Ensure OP™ | ProMxA is a purpose-built test system designed to validate fixed and variable displacement oil pumps at the end of the production line using air as a test medium.


Here's a test system that already meets your needs. 

Tirelessly compiling OEM test specifications, interpreting and summarizing requirements and defining the perfect test system is time better spent making the perfect mechanical oil pump.



Robust driveline subsystems, engineered for prolonged use between extremes.



Accurately measure key parameters for vane or gear/rotor engine or transmission pumps. Eccentric ring measurement for variable displacement pumps (optional).


Physical Interface

Universal fixture and driveshaft, with locating features included. Contains hydraulic clamping for production or audit applications.



Simulate various test conditions according to industry standards.


Designed for international power sources and safety considerations with minimal to no modifications.


An industry-leading National Instruments data acquisition system is integrated with a Windows Embedded controller.





ATA Assist™ allows you to submit a request for assistance 24/7.

ATA Accurate™ is an annual on-site system calibration which meets the ISO17025 standard accredited by A2LA.

ATA's unique "gull-wing" enclosure allows safe and easy access to the unit-under-test and for essential maintenance activities.

Intelligence comes standard.

Introducing FloInt™

All ATA Ensure™ test systems come with FloINT™ (Flow Intelligence) software, built from the ground up with features specific to testing and analyzing fluid/hydraulic components. We include common mechanical oil pump test profiles (i.e. air flow leak test, performance test, pressure regulation test, etc.), or you can create your own with our easy drag-and-drop interface. 


Double your throughput.

Ensure OP™ | ProMxA is available in two configurations:

  • OP | ProM1A: Standard single unit-under-test (UUT) system.
  • OP | ProM2A: Dual spindle/drive assemblies and measurement circuits to test two UUTs in parallel, doubling throughput.

The Ensure OP™ | MxA is a system that can handle end-of-line functional and audit quality assurance applications with ease.

It comes standard with:

  • Inlet pressure measurement
  • Hydraulic clamping
  • Production package
    • Part identification
    • Stack light
    • Large indicator lights
  • Automated front door
  • FloINT Scripting Package
  • FloINT User Management
  • Database Saving
