Flowkooler High Flow pump for the Land Rover Series II, IIA and III has a CNC machined billet impeller designed with an increased vane count and a reduced plate-to-impeller clearance. 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.
Slow speed rock crawling means lower fluid flow and limited air flow. A good radiator and a hi flow pump will keep your engine temperature down whether your crawling in the hills near Birmingham or in the desert near Moab.
FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.
