E320C Excavator Engine Water Pump 3066 Diesel Cooling Pump Assembly for 320C Machines

E320C Excavator Engine Water Pump 3066 Diesel Cooling Pump Assembly

This engine water pump is built as a direct replacement for the 3066 diesel engine used in 320C / E320C hydraulic excavators. It circulates coolant through the cylinder block, cylinder head and radiator so that coolant and oil temperatures stay inside the normal working range during continuous digging, lifting and travel work. Each unit is assembled with a cast iron housing, a balanced impeller and a mechanical seal, then flow and pressure tested before packing.

Key Selling Points

• 3066 Diesel Engine Water Pump Assembly — a complete unit including housing, impeller, shaft, bearing, mechanical seal and gasket seat, ready to bolt on.
• Precise 320C Fitment — mounting flange, pulley hub and hose connections machined to original dimensions, so no modification is needed during installation.
• Cooling Performance Tested — every pump is flow and pressure tested to confirm seal tightness and stable coolant delivery when the machine works under load.
