Tilton cooler pumps are ideal for pumping oil through transmission and differential coolers. Featuring a 12-volt continuous duty electric motor, cooler pumps feature an internal bypass valve and are self-priming up to eight feet above the source from which it draws. Tilton cooler pumps are a positive displacement type of pump, so its output is directly proportional to the motor speed. For example, if a lighter load increases the motor speed by 25%, then the flow rate increases by 25% as well.
