Our diesel engine driven water pumps that are mounted on a trailer can easily be transported from one location to another. The high-power self-priming pump features robust self-priming capability, enabling automatic gas evacuation from the suction line without pre-filling water and quickly initiating normal operation. This characteristic makes it particularly advantageous in scenarios requiring frequent relocation or height-restricted installations. For instance, it is extensively utilized in agricultural irrigation and firefighting water supply applications.

Signs of Diesel Engine Pump Set Failure

Leaks:

An early sign of a leak is coolant leaking from the water pump. There may be a hole in the lower part of the water pump. If coolant leaks from the drain, a leak is present and a small amount of dry coolant around the hole is normal. Depending on the colour of the coolant, it may be green or pink.

Noise:

A water pump that is about to fail will make a grinding and rumbling noise. If the water pump shaft is loose, it means the water pump is damaged.

Overheating:

The water pump may also fail as the engine temperature rises, which is another sign of failure. In addition, there are many reasons why a water pump can overheat, so it is important to diagnose the problem promptly. If the engine temperature is higher than normal, the cooling system needs to be checked
