Proflow’s new range of Mechanical Water Pumps are made from lightweight cast aluminium and feature CNC machined threads for exact fitment. Proflow Pro Series Water Pumps are ideal for high performance street use. They feature an eight blade cast iron anti-cavitation impeller that provides optimum water flow. The impeller also limits high rpm cavitation (air in the water) and will not crack, corrode, or fatigue like aluminum impellers can. Proflow Water Pumps also feature a heavy-duty 5/8” shaft, bearing, and seal, and all necessary bracket bosses and hose connections. Proflow cast aluminium water pumps weigh approximately 30 to 50 percent less than stock iron pumps.
