Water Pump Is Necessary For Commercial Applications

A water pump is necessary for both commercial and residential applications. The pump forces the water from its reservoir into the tank, offering pressurized fluid at various points.

The pump can be used to service the household water supply in other industries such as power production and automobile.

The water pump components make it possible for the device to operate efficiently and provide the energy required to push the water into a storage tank.

The main elements of a water pump include:

The outer casing
Impeller
Bearing
Hub
Seal

The seal

As a pump is the core of the cooling system, a seal is the heart of the pump.

The function of this component is to prevent the bearing assembly from coming into contact with abrasive contaminants and coolants.

Once these substances have gotten into the bearing assembly, the lubricant of the bearing will be washed away. If the failure of the seal is undetected, the bearing will fail and lead to the snapping of the bearing shaft.

Two main aspects affect the life of a seal and could lead an early pump failure. First, seal failure and leakage can take place from high-temperature operations.

For instance, an overheated engine that works in low levels of coolant causes possible distortion or the flatness of seal face. Secondly, failure could result from abrasive deposits or contamination between surfaces of the seal.

When diagnosing premature failures of seals, you need to be careful so as not to misunderstand small leak holes stains as signs of failures.

The seals are supposed to leak slightly as a small amount of coolant is required to lubricate the faces of the seal.

Nonetheless, when the drips are in large quantities, you will need to replace your water pump.

The Bearing

The shaft bearing assembly is lubricated and combines two rows of rollers, an outer race, a precision ground, and two double-lipped seals lubricated with grease.

The rollers are made up of either ball/roller or ball/ball-type bearings with a lubricant that is added to keep the operation of the bearings smooth and in place.

The bearing is essential to the rotation of impeller that moves a coolant throughout the entire cooling system.

In most cases, failures of the water pumps are falsely attributed to the failure of bearings while in fact, the problem results from a leaky seal.

It’s imperative to note the difference between a bearing grease seal and a water pump seal.

As mentioned earlier, the function of the water pump seal is to protect the bearing assembly from fluids and abrasive contaminants.

On the other hand, the role of the bearing seals is to make sure the grease remains in place when inside the bearing assembly.

For that reason, checking for contaminants becomes the first step in diagnosing the failure of water pump.

You should remember that the failure of the bearing assembly means there was a failure in the seal.

In that case, the pump's seal failed in keeping contaminants and other materials from getting into the bearing assembly.
