FlowKooler water pump prevent engine overheating. Each impeller is designed to generate higher flow rates and increase system pressure. Increasing coolant flow rate through the block reduces the cycle time between the engine and the radiator providing more opportunity for heat exchange. When flow rate is maximized, the higher flow rates raise engine block pressure to prevent the formation of steam pockets in the water jacket and the vapor barrier that can cause hot spots on cylinder walls.
Each of our billet aluminum impellers is precision machined to achieve tighter clearances between the vanes and the casting volute. Each is shrouded to contain the flow. This design combination generates higher flow rates that reduce the cycle time between the source and sink. It is that simple.
Our impeller designs achieve a more efficient flow curve to conserve valuable horsepower. Less power used to move the coolant through your system means more power you have to move your tires down the road.
Higher flow rates help cool at lower speeds but they also raise the block pressure at higher rpm. Building that pressure helps prevent hot spots & steam pockets from forming on cylinder walls. Higher pressure also prevents early detonation and reduces the onset of cavitation.
All good stuff!
Your coolant begins to deteriorate almost immediately. FlowKooler CNC machines each impeller from corrosion resistant 6061 billet aluminum and anodize finishes each one with a Military Spec MIL-A-8625 Type II Class II surface coating.
This analogy was shared with us and we share it with you.
Early liquid-cooled engines surrounded their cylinders and heads with lots of water in large water jackets and often had no pump at all. The coolant circulated by convection e.g. hotter water expands, becomes less dense, and consequently slowly rises out of the engine through a really large hose to the radiator where it was cooled, contracting slightly and thus became more dense, falling back to the engine through a second hose at the bottom of the radiator.
This thermosiphon system worked well but as engines became more more powerful the thermosiphon’s slow circulation rate permitted the formation of steam pockets, which resulted in overheated engines.
Early engineers determined that moving the water through the engine fast enough to scour away potential steam pockets which prevented overheating and thus added water pumps. There were still problems so next they began to make the coolant passages smaller. Doing so raised the block pressure and the coolant had to move through them faster.
We did not invent it. We cannot explain it better that they did so here it is.
