Water Pump

Why Do Engines Need Water Pumps?

When your construction machine is running, the coolant becomes hot after passing through the motor, so the water pump needs to send it back to the radiator for cooling, otherwise, the engine will be damaged due to overheating.

What Is an Engine Water Pump?

It is a crucial component of the cooling system of loaders, dozers, generators and excavators, such engine spare part is usually driven by a belt or electric motor attached to the engine shaft. The water pump pumps the coolant out of the radiator through the coolant system, into the engine and back to the radiator. The heat absorbed by the coolant from the engine is transferred to the air at the radiator. Without a water pump, engines can be damaged by overheating, and loaders, tractors excavators and bulldozers can only run for a few minutes before overheating.

Main Types

There are two main types, and they have similar essential functions but vary by model and make.

Centrifugal pumps are the most common type and are usually found in older construction machines. They are driven by a pulley and belt connected to the engine's crankshaft.

Electric water pumps: This is an increasingly popular type in modern construction machines, an electric motor powers them and can be controlled by the Engine Control Unit (ECU). If you want your excavators, loaders, dozers, and generators to have more control over the coolant flow and be more efficient, the electric one is your best choice.

Signs Of Bad Engine Water Pump

A malfunctioning or damage can cause various problems with the cooling system and even result in engine damage. Here are a few warning signs:

• You find that coolant is leaking from the front of the engine or from the drain hole of the water pump
• It is found that the high-temperature light is on, which indicates that the engine is overheated, and the engine needs to be shut down as soon as possible under safe conditions to avoid damage to other components
• Grinding noises or roars are heard, which may be caused by worn bearings or damaged impellers.
• Water pump pulley loose or wobbly

If you notice any of these warning signs, be sure to have your excavators, loaders, dozers, and generators inspected by a mechanic as soon as possible to prevent further damage to your engine. Also, regular inspections of your radiator and radiator cooling fan are helpful. If your water pump has affected your engine operation, then a new replacement part is a wise investment.
