Meziere 300 series electric water pumps are the top of the line in electric water pumps, capable of flowing 55 gpm--enough for a 600 hp oval track car or a 2,200 hp Pro Mod. They have larger internal passages and heavy-duty motors, and are available in radiator, remote-mount, or engine-mount versions. These pumps feature CNC-machined aluminum housings, epoxy-coated motor windings, an RF suppression circuit, and a one-piece carbon-ceramic seal. This model does not accept heater or bypass hoses as a standard. These maybe added at the factory for an additional cost. Please call for details. Our 2 year, unlimited mileageguarantee and full satisfaction money back guarantee should convince you that buying Meziere is buying value!
