Oil Pumps: all moving parts are forced lubrication; the large capacity gear pump provides pressure lubricating oil to lubricate the bearing and cool the piston; the oil cooler, full flow filter and bypass filter ensure the oil is in good condition.

Fuel pumps: Cummins PT fuel system, optimized combustion, surging power; STC step-by-step timing system ensures better combustion under full working conditions; low pressure fuel supply system is adopted, with one-way fuel circuit, which is safe and reliable.

Water pumps: forced water cooling by gear centrifugal pump is adopted, and the design of large flow channel is good. The rotary mounted water filter and special DCA additive can effectively control the acidity of the coolant, prevent corrosion and cavitation and remove impurities.
