Cardinal pumps for demanding transformer oil applications

Unifin offers a line of transformer oil pumps manufactured under the company’s Cardinal brand. Cardinal pumps are the industry’s only pumps specifically designed to meet transformer oil applications. They are rated for continuous duty at operating temperature ranges from -40C to 100C. Other special features include permitting thermo-siphon flow when the pump is not operating, allowing natural convection even when the pump is completely shut off.

All Cardinal pumps offer rugged split casing design with heavy-duty class 30 cast iron used for the pump casting, motor enclosures, impellers and volutes. Large thrust face sleeve bearings also extend life, minimize wear and reduce maintenance. Because of their design, these pumps are low maintenance and long-lasting. With no mechanical seals, repair and upkeep is reduced in utilizing two gasket seals on each pump.

Cardinal manufactures hundreds of different pump configurations used in all of Unifin’s wide range of transformer oil coolers. London, Ont.-based Unifin International is a world-leading supplier of cooling equipment and transformer oil pumps and valves to the power generation and power transformer industries.
