Cooling Tower Pump Head

The most common open system is the cooling tower portion of a chilled water system as depicted below.

Cooling tower pump head.

The towers themselves are enclosed steady flow devices for cooling water by evaporation through direct contact with air. 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. Range of head and flow rate the required heads for fresh water operation usually lie within 5 to 15 m. If you don t size the pressure drop right it won t get there.

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. 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. 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.

526 charlotte avenue burkburnett tx 76354. The water collects in the cooling tower sump before being pumped around the loop again. For most industrial manufacturing electric power generation and even air conditioning needs cooling towers are a critical element of the design. It must also provide the energy head necessary to raise water from a low to a higher static head level.

Sizing the tower water pump can be a challenge too. Use these pumps to move water and lubricating oil in boiler feed systems cooling towers and heat exchangers. They extract heat to the atmosphere through evaporative cooling. Cooling towers work on the principle of heat rejection.

Wpi can provide you with a pump to supply you process or application. The npsh r curve is in red at the bottom. For the tower piping circuit the pump must overcome the piping flow friction loss. Supply without using electricity these pumps install directly in your pipeline and activate when water flows into the pump 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. Pumps are typically sized for 65 feet of head. High pressure metering pumps for chemicals. Cooling water pumps are used for supplying heat exchangers with cooling water.

Piping condenser cooling tower losses and valves. Furthermore whaley designs and builds cooling tower pump tank systems and chilled water pump tanks.
