Mezieres aluminum 300 Series pumps are the highest flow electric water pumps on the market. Originally designed for NHRA Pro Stock cars, most people use these on street high performance cars. Although the appearance of these models are similar to the 100 series pumps, internally everything is larger. Inlet inside diameters are 1-3/8'' or 1-1/2''. The impeller and pump cavity allow for greater volume of water. The heavy duty motors provide increased torque and RPM. The resulting flow rate of 55 gallons per minute is enough to cool anything from 650+ HP street cars to circle trackers to a 2200 HP Pro Mod. We strongly recommend this series pump for supercharged, nitrous, turbo high performance street engines. The 300 series pump is also available in remote mount versions if needed. 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. Some pumps feature a welded inlet connection but most pumps are machined with a NPT port(s) to direct water into the pump using one of the inlet adapters that you choose to best suit your needs. Inlet adapters are available in slip-on rubber hose style to AN sizes, inlet fittings are sold separately and not included with pump. Most pumps and fittings are available in chrome, polished or anodized finishes. Extended inlets, extensions, and angle adapters are also available. Meziere pumps are American made with pride and quality far superior to any other performance aftermarket company. Don't be misled by ''Others'' inflated flow numbers and outlandish claims. Meziere says what they mean and mean what they say. The 2 year, unlimited mileage guarantee and full satisfaction money back guarantee should convince you that buying Meziere is buying value!300 Series Water Pump Features:
