Modern Centrifugal Pumps and How They Changed HVAC Units

The use of air conditioning systems in Australia has seen a considerable rise over the years, with a great percentage of residential and commercial properties having one or more of these installed.

With many consumers considering these space cooling devices as a must-have for making a building habitable, air conditioners and everything that goes into their creation have undergone big improvements. One such component is the centrifugal pump.

The workhorse of all HVAC units

Since the onset of HVAC (heating, ventilation, and air conditioning) systems, centrifugal pumps have served as their primary workhorse. They play major roles in the performance of boilers, chillers, and cooling towers. Even domestic water systems, as well as hydronic distribution systems, will not function properly without these components.

Their primary roles

The primary role of the pump is to generate centrifugal force, hence the name, which it does through turning its built-in motor. The force it creates causes the liquid to draw towards the motor, which it then discharges through the volute’s opening. Furthermore, the pump creates a differential pressure, which in turn, allows the flow of water throughout the pipes.

The evolutionary changes

Pump manufacturers today offer products that have evolved from their humble beginnings dating back several decades ago. From enhanced impeller designs to the use of higher quality construction materials and the development of greater-performance bearing and seal designs, the modernised version of these essential HVAC components now allow for considerably increased HVAC operation efficiency.

With the right choice of an innovative centrifugal pump, HVAC manufacturers, contractors, and repair specialists can offer their clients with better value for their money.
