Built to Flow 55 Gallons Per Minute!
Perfect for 12- and 16-Volt Electrical Systems

This water pump is Meziere's most versatile to date, combining an inline design, 55 gallons per minute free-flow rating, and interchangeable fittings. Meziere 300 Series Water Pumps move more water and produce more pressure than any other electric pump on the market, which means better protection for demanding high-horsepower engines. Meziere also makes this pump with a built-in thermostat circuit to provide the option of adding a true thermostatic circuit to expedite engine warm-up (beneficial for engines with aluminum blocks because their tighter clearances require heat to avoid excessive wear). The pump housing, impeller, and motor cap 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 to isolate the epoxy-coated motor from coolant for lasting reliability. The motor also has a radio frequency suppression circuit in the motor's brush card to reduce ignition (RF) interference. Fittings sold separately.
