Morgo Ariel Square Four MkII Rotary Oil Pump

£217.95 ex VAT


The Morgo Ariel Square Four MkII high performance rotary oil pump is made to very fine limits, from the best materials to give long and trouble free service.

The rotary pump is designed to give maximum lubrication at all speeds, this is achieved by doubling the oil flow around the engine.  The oil pressure is still controlled by the pressure relief valve, which on this model is integrated into the pump and is set at 55psi. The maximum pressure is never greater than the relief valve will allow.
