Mechanical Engine Oil Pumps

In the relentless pursuit of efficiency, the engine oil pump has become more complex. Variable displacement pumps, with solenoid or pressure actuated eccentric rings, multiple outlets and integrated vacuum (tandem) assemblies are becoming more common.

Ensure OP™ | M is a purpose-built test system designed to characterize and benchmark new engine pump prototypes and validate ones at the end of the production line.


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 engine oil pump.



Robust driveline and fluid conditioning subsystems, engineered for prolonged use between extremes. 



Accurately measure key parameters for fixed or variable displacement engine oil pumps.

Physical Interface

Universal fixture and driveshaft allows for flexible component-specific adapters to test multiple pump models efficiently.



Simulate various test conditions (i.e. fluid/ambient temperature, aeration, contamination, etc.) according to industry standards.


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


Comes with an industry-leading National Instruments® data acquisition system, 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.

Rapidly cool the pump body and test fluid (by conduction) to -40°C in a quicker, more efficient manner than a thermal chamber.

Aerify™ Measure can accurately measure the gas concentration of oil in real-time. Aerify™ Control can introduce air (up to 30% aerated) to better simulate the engine environment.

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 oil pump test profiles (i.e. high speed flow limit test), or you can create your own with our easy drag-and-drop interface. 


Validation comes in many flavors.

While the measurement and control characteristics of a test system should always remain accurate and precise, some applications require special consideration. Ensure OP™ | M is available in four variants:

  • OP | DurM: Designed for robust endurance testing
  • OP | PerM: Engineered for the most precise measurements
  • OP | ProM: Built for efficient and effective end-of-line validation
  • OP | M: A system for a specific set of test requirements

Available in single or dual-headed configuration, the Ensure OP™ | DurM is an effective system for thousand-hour tests. It comes pre-loaded with a mechanical oil pump durability test plan.
