Cooling Tower Pump Head

A break in the piping system occurs where the water exits the spray nozzles and is exposed to air in the fill section of the tower.

Cooling tower pump head.

The most common open system is the cooling tower portion of a chilled water system as depicted below. The required head is determined by the type of cooling system. Manufactures open loop cooling towers and closed loop cooling towers at its facility in north texas facility in burkburnett tx. A distinction is made between wet cooling and dry cooling processes.

For most industrial manufacturing electric power generation and even air conditioning needs cooling towers are a critical element of the design. Supply without using electricity these pumps install directly in your pipeline and activate when water flows into the pump head. Piping condenser cooling tower losses and valves. If you don t size the pressure drop right it won t get there.

The towers themselves are enclosed steady flow devices for cooling water by evaporation through direct contact with air. The water collects in the cooling tower sump before being pumped around the loop again. It must also provide the energy head necessary to raise water from a low to a higher static head level. High pressure metering pumps for chemicals.

Cooling water pumps are used for supplying heat exchangers with cooling water. Pumps are typically sized for 65 feet of head. Here is an example of a pump selection using a bell and gossett side suction top discharge pump designed for 3000 gpm at 70 feet of head. Keep in mind that you need the pump to develop enough pressure to get water to the highest and farthest places in the plant.

Use these pumps to move water and lubricating oil in boiler feed systems cooling towers and heat exchangers. Pump head calculation open cooling tower artisi mechanical 1 sep 08 05 24 biginch you are of course correct the additional flow into the return leg from the tap in point to the discharge will cause a shift of performance of the older pumps anyway as the total head on these pumps will increase due to higher friction loss. Wpi can provide you with a pump to supply you process or application. If you read up from 3000 gpm to that curve and across to the right the npsh r is 15 feet of absolute pressure or about 16 on a vacuum gauge.

For the tower piping circuit the pump must overcome the piping flow friction loss. 526 charlotte avenue burkburnett tx 76354. Cooling towers work on the principle of heat rejection. They extract heat to the atmosphere through evaporative cooling.

Their flow rate varies depending on the heat flow to be dissipated. Range of head and flow rate the required heads for fresh water operation usually lie within 5 to 15 m.
