Power factor is a measure of how effectively electrical power is being used by a system. It is defined as the ratio of real power (measured in kilowatts, kW) to apparent power (measured in kilovolt-amperes, kVA). Mathematically, it is expressed as:

Pumps are essential components in HVAC (Heating, Ventilation, and Air Conditioning) systems, playing a crucial role in maintaining optimal temperature levels and ensuring efficient operation. These pumps are responsible for circulating the system fluid, facilitating the transfer of heat and enabling the cooling process. By continuously moving the fluid, pumps help transfer heat from the indoor environment to the outside, thereby maintaining comfortable temperatures indoors.

Horizontal Split Case Fire Pump
These pumps use a between-the-bearings design, which means that the impeller is supported by bearings on both sides. This design provides more support for the impeller and enables it to rotate more efficiently under stress. HSC pumps place the suction and discharge nozzles (flanges) in the bottom half of the casing, on opposite sides. The impeller shaft is positioned slightly above the flanges. This sturdy but simple design is particularly suitable for higher flow applications, because it reduces thrust loads on the pump shaft and allows for operation over a broad range of flows.
