Tilton Cooler Pump

For Standard Oils & Coolants | Self-Priming | Internal Bypass | Continuous Duty Rated

The Tilton Cooler Pump (Buna) is ideal for circulating oil through transmission and differential coolers in motorsport and performance applications. Its versatile design also makes it suitable for fluid transfer and coolant circulation tasks across a variety of builds.

This high-performance pump features an internal bypass valve and is self-priming up to 8 feet above the fluid source. As a positive displacement pump, its flow rate is directly proportional to motor speed — meaning that if motor speed increases by 25%, so does the flow rate. Built for standard oils and coolants, this pump offers the reliability and flexibility racers and builders demand.


Key Features

  • Self-priming up to 8 feet
    Easily draws fluid from below the pump without the need for manual priming.
  • Internal bypass valve
    Helps manage pressure variations while protecting the system.
  • Positive displacement design
    Consistent, scalable flow — proportional to motor RPM for responsive performance.
  • Buna-sealed construction
    Specifically designed for use with standard oils and coolants.
  • Continuous duty rated
    Designed for applications where the pump needs to operate continuously for longer than 2 hours at a time without cool down. Engineered for up to 1000 hours of continuous use.
