Built to Keep Cars CoolThe 100 Series Pumps are very lightweight and flow 35 to 40 gallons per minute. They are ideal for mild street and Sportsman drag cars. The pump housing, motor cap, and impeller are CNC-machined from 6061-T6 billet aluminum for superior corrosion resistance. The stainless steel impeller shaft runs through a 1-piece carbon-ceramic seal that isolates the epoxy-coated motor from coolant for years of reliable service. The motor has a radio frequency suppression circuit in the motor brush card to reduce ignition "RF" interference. Machined with a 1.44" inlet. Available polished or anodized.
