Mechanical Water Pumps

Efficient and effective cooling is a mandatory requirement for any automotive application. The testing of mechanical water pumps must validate they can reliably provide high flows to meet the cooling demand across a wide temperature range, with varying belt tension loads.

Ensure WP™ | M is a purpose-built test system designed to characterize and benchmark new mechanical water pump prototypes and audit samples in a production environment.

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 water pump.



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



Accurately measure key parameters for mechanical centrifugal (impeller) water pumps, with laminar flow and minimum pressure drop

Physical Interface.png

Physical Interface

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



Simulate various test conditions (i.e. hot/cold fluid, belt tension, 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 test fluid to -40°C in a quicker, more efficient manner than a thermal chamber.


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 water pump test profiles (i.e. temperature, speed and pressure sweep and ramp), 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 WP™ | M is available in four variants:

  • WP | DurM: Designed for robust endurance testing
  • WP | PerM: Engineered for the most precise measurements
  • WP | ProM: Built for effective audit/production validation

The Ensure WP™ | DurM is an effective system for thousand-hour tests. It comes pre-loaded with a mechanical water pump durability test plan.
