Why Your Water Pump Pressure Performance Matters

28 September 2020

Water pumps are utilised in a lot of applications and industries as they help in transporting water or any other type of fluids from one point to another. One crucial aspect that drives the effectiveness and quality of the performance of water pumps is pressure. Without the right level of pressure, water pumps might find it difficult to move fluids across buildings and industries.

Generally, water pumps can be used in residential, industrial, and commercial use. No matter what type of industry they are utilised, all water pumps can transfer water or fluids from one location to another. Some factors that will only separate them from each other are their overall capacity, performance, and the way they operate or move the fluid to another location.

Water Pump Classifications

Water pumps can be grouped into two categories: positive displacement water pumps and centrifugal water pumps. The classifications of water pumps are based on the way they move the fluid from one location to another.

Positive displacement water pumps can take in and transfer a fixed volume of fluid into the pump through the suction valve, transferring it inside the pump, and then forcing it out through the outlet valve. This type of pump is recommended for applications that deal with sensitive solid materials or those that have to manage high viscosity liquids. The high efficiency of these water pumps, as well as their ability to remove air in the lines, make them preferred by some industries over centrifugal water pumps.

Centrifugal water pumps, alternatively, have a rotating impeller that can move liquids through the pump. This device can pressurise the discharge flow of the liquids. All types of liquids, which include those that have low viscosity, can benefit the most with this type of water pump due to their associated properties. The presence of a continuous pressure source and their pressure boost from the intake line make these water pumps perfect for handling large volumes of low viscosity fluid in a low-pressure environment.

Importance of Pump Pressure

Numerous factors can affect pump performance. Some of these factors include internal clearances, surface roughness, mechanical losses, the viscosity of the fluid, impeller trim, and high suction specific speed. Another factor that can affect the functionality of a pump is its pressure performance.

Water pressure is the measure of force that is utilised to move water or other liquids from one point to another. Without pressure, the transfer of liquids would be truly difficult. If the pressure of the water pump is too low, then it would take a long time just to transfer liquids from one place to another. Alternatively, too high pressure in water pumps can cause substantial damages to components that the liquid will flow into. Water pressure that is too high can also cause wasted water and instances of flooding.

Keeping the pressure on the recommended level of a water pump can easily improve its efficiency and performance. The liquid flow from one place to another will also be regulated properly due to the presence of optimum water pump pressure.
