FlowKooler Hi-Flow mechanical water pumps resolve low-speed heating problems by doubling flow rates at low rpm and idle. CNC precision-machined impellers feature larger diameters, increased vane count, tighter clearances, shrouding, and porting. These unique design features help drop engine temperatures by up to 30 degrees, increase the block pressure to prevent hot spots on cylinder walls, and stop the formation of steam pockets in the block, all while delaying the onset of cavitation at higher rpm. FlowKooler Hi-Flow mechanical water pump impellers are protected from electrolysis and corrosion with a military-grade Type II Class II anodized surface coating.

PRW High Performance mechanical water pumps are engineered to deliver increased water flow faster. These super velocity pumps significantly improve cooling for all street, high performance, and racing applications. The low pressure-injected, A356 aluminum alloy pump bodies are complemented by a precision, high-flow cast iron impeller design. Pressure-balanced water passages equalize flow and minimize engine hot spots at any speed. PRW High Performance mechanical water pumps are excellent alternatives for not only racers, but also trucks, towing, and motorhome applications. Order the model recommended for your specific vehicle and engine size. Features, items, and specs: * 35 gpm at 4,000 rpm with minimal cavitation and proportional increased flow rates at 5,000+ rpm * Aircraft industry tolerances * Heavy-duty 0.75 in. diameter steel shafts * Billet steel hubs and shielded-seal roller ball bearings * Back plate O-ring sealed for most applications * System Basis Chip (SBC) applications include adjustable hardware
