Flowkooler designed a high flow water pump with a CNC machined billet impeller to increased vane count and a reduced casting to impeller vane clearance to take care of the problem. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. FlowKooler introduced the first hi flow pumps for the
