EMP Stewart Pro Series water pumps are the latest technology for professional racing. By utilizing twin volute housing and a replaceable water pump cartridge, they offer a perfectly balanced flow between both sides of the block. They use less horsepower and can move more water than any other pumps. Pro Series pumps are cost-efficient by allowing just the cartridge to be replaced, making it no longer necessary to change the whole water pump. The cartridge can be changed out very quickly by removing the pulley and four bolts. All Pro Series water pumps use an O-ring to seal the cartridge and do not use a backing plate, so there is no gasket to leak. Whether you race circle track, road race, or drag race, professional or amateur, you will benefit from these water pumps.
