All US Motor Works mechanical water pumps are designed and tested to meet or exceed OEM specifications. Using advanced research, they include efficient impellers, case-hardened bearings, and unitized seals to provide optimum cooling with performance and longevity. Every US Motor Works mechanical water pump is supplied with a quality mounting gasket and other accessories (seals/gaskets) necessary to properly complete the installation.

US Motor Works mechanical water pumps feature:

* Case hardened bearings that meet specific radial torque and axial load requirements; they have higher load capacities, are tough on the outside, yet flexible on the inside … ideal for withstanding imbalance or vibration
* All mounting surfaces are CNC-machined for easy installation, precision sealing, long component life, and maximum efficiency
* Inspected and tested to ISO: 9001:2015 standards
* Industry-leading metal impeller integration; metal impellers handle more torque and higher temperatures than plastic to improve high-rpm performance and combat failure caused by broken or distorted impellers
* Highly durable metal impellers are also chemical-resistant, withstand variables in high-mileage engines, and are better for transit and storage
