Mechanical Seal Water Pump

Our Mechanical Seal Water Pump circulates essential coolant around various circuits, providing the required thermal transfer of heating or cooling for your application. We use a high-quality mechanical seal to separate the coolant and the impeller head from the motor, and long-life brushless motor technology to guarantee lasting reliability.

Delivering high flow at lower pump speed and built with a no-media function to protect against running dry, our Mechanical Seal Water Pump is built using premium, EU-sourced materials and is made from a die-cast, heavy-duty aluminium body.

In series production since 2017 and found in thousands of vehicles across the world, our range currently has two models available to meet a variety of flow and coolant temperate requirements.
