Dependability
Hydromatic pumps oil-filled motor keeps the windings cool, eliminates moisture, and permanently lubricates the bearings, to provide reliable pumping service. You can depend on Hydromatic pumps to provide years of reliable service. Currently, there are thousands of units operating trouble-free throughout the world. As one of the oldest pump manufacturers in the world, Hydromatic offers you field-proven pumps and systems for all your requirements. Hydromatic has a 5 year pro-rated warranty available. We also supply complete technical support, and ongoing engineering assistance for the life of the pump.

First, the oil bath keeps the motor and bearings cool by dissipating heat and maintaining the correct operating temperature. The oil transfers heat generated in the motor windings to the housing where it is dissipated. Second, the oil bath locks out airborne moisture contamination which destroys motors and bearings. Air carries moisture that condenses with temperature changes and causes premature motor and bearing failure.

And, the oil bath permanently lubricates the bearings which minimizes heat and flushes contaminants away from bearing races. Heat and contaminants cause grease breakdown that leads to premature failure of grease-packed bearings supplied by other manufacturers. You get long pump life because the oil-filled motor dissipates heat from the windings, through the oil, to the outer housing.
