Cooler Pump Continuous Duty Buna Diaphragm

The TILTON Cooler Pump Continuous Duty Buna Diaphragm (model 40-527) is a specialized coolant circulation pump designed for high-performance automotive cooling systems. It is ideal for applications where reliability under sustained demand is critical, such as in track-focused builds, competition vehicles, or demanding street applications. This pump is engineered to handle continuous duty cycles that conventional systems cannot sustain.

Featuring a diaphragm-driven design, the TILTON pump is perfect for closed-loop cooling circuits in race cars and high-output engine builds. The flexible Buna rubber diaphragm allows for continuous cycling, ensuring consistent coolant flow across varying pressure conditions. This material is chemically compatible with standard coolants and offers excellent durability under thermal cycling, making it resistant to degradation from heat spikes and freeze-thaw cycles.

Mechanics and engine builders appreciate this pump for its ability to extend service intervals and reduce unexpected failures during critical competition runs or long-duration street use. It is particularly beneficial for custom cooling loop installations, turbo system builds, and vehicles that require auxiliary coolant circulation independent of the engine-driven pump.
