Vertical Cooling Tower Pumps

Vertical turbines are commonly used in all types of applications from moving process water in industrial plants to providing flow for cooling towers at power plants from pumping raw water for irrigation to boosting water pressure in municipal pumping systems and for virtually every other imaginable pumping application.

Vertical cooling tower pumps.

Smart pumps are also designed to help reduce operating and maintenance costs. For the tower piping circuit the pump must overcome the piping flow friction loss. The amplitude of the vibration response can be amplified 2. 2 3 cooling towers in healthcare cooling is especially important in hospitals and medical centers.

Cooling water pumps are used for supplying heat exchangers with cooling water. A margin of safety should be provided between the pump vane pass speed frequencies and major structural and or pipe hydraulic natural frequencies. A distinction is made between wet cooling and dry cooling processes. The major characteristic of the cwp is their high flow.

Range of head and flow rate the required heads for fresh water operation usually lie within 5 to 15 m. Hospitals require an ambient temperature of 72o 24 7. Piping condenser cooling tower losses and valves. They comply either with iso asme or api standards and guarantee reliable and efficient processes.

The required head is determined by the type of cooling system. The pumps are usually horizontal end suction split case double suction or vertical turbine pumps. Their flow rate varies depending on the heat flow to be dissipated. They are often operated with both shower nozzles and fans running at full capacity meaning energy waste due to not adapting to the specific load.

It must also provide the energy head necessary to raise water from a low to a higher static head level. Grundfos offers pumps controlled by constant discharge temperature and fan motors controlled by the. Cooling towers are usually not controlled according to load. In medium to large size gas fired combined cycle power plants the cwp are vertical column type.

Typical acceptable margins are 15 25. This is of special concern with variable speed large multistage horizontal and or vertical pumps. Cooling water pumps cwp provide the fresh water to cool the exhaust steam in the condenser and pump it back to the wet cooling tower or the outlet of open cooling system. Numerous sizes hydraulics and material combinations are particularly well suited for use in applications where uncompromising reliability and.
