Cooling Tower Pump Type

Also known as a flexible impeller pump it creates a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump.

Cooling tower pump type.

Determining a cooling tower type and understanding some of the key design considerations will get you headed in the right. Correctly piping the suction and discharge of your cooling tower condenser water pump is critical. For the tower piping circuit the pump must overcome the piping flow friction loss. Natural draft cooling towers.

Their flow rate varies depending on the heat flow to be dissipated. The spray header is located on top as shown in the sketch. Piping condenser cooling tower losses and valves. As their name implies natural draft cooling towers rely on natural convection to circulate air throughout the tower which then cools the water.

The required head is determined by the type of cooling system. The cooling tower water circulating pumps are critical to the chiller systems they serve. The axially split design allows easy removal of the top casing and access to the pump components bearings wear rings impeller and shaft seal without disturbing the motor or pipe work. Basic cooling tower equipment.

The spray nozzles spray the warm water inside the tower. Your chilled water system may even have more than one type of chill water pump with a primary pump circulating water through your chiller and another to circulating water through the building. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near. Warm water from the condenser is fed to the spray header by means of a pump.

It is important to have some excess flow in the pump and tower design for these situations. A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. The paco kp kpv kpvs split case pump is a single stage non self priming between bearing centrifugal volute pump. This pump has a totally enclosed nonventilated tenv motor that is cooled by the liquid being pumped.

Some fairly catastrophic events can occur if either is improperly installed. Air movement occurs due to differences in density between the entering air and the internal air within the tower. The sketch shown below explains about the spray type of cooling tower. It must also provide the energy head necessary to raise water from a low to a higher static head level.

Cooling water pumps are used for supplying heat exchangers with cooling water. A distinction is made between wet cooling and dry cooling processes. Starting with the suction piping it is important to take precaution to avoid air pockets which can destroy a pump in pretty short order.
