Vertical Cooling Tower Pumps

The vl vls inline pumps have proven to be extremely versatile often exceeding the requirements for a variety of market applications such as chilled water condenser water and hot water systems.

Vertical cooling tower pumps.

This is of special concern with variable speed large multistage horizontal and or vertical pumps. In medium to large size gas fired combined cycle power plants the cwp are vertical column type. They comply either with iso asme or api standards and guarantee reliable and efficient processes. Cooling towers are usually not controlled according to load.

Range of head and flow rate the required heads for fresh water operation usually lie within 5 to 15 m. The amplitude of the vibration response can be amplified 2. Grundfos offers pumps controlled by constant discharge temperature and fan motors controlled by the. The required head is determined by the type of cooling system.

Cooling water pumps are used for supplying heat exchangers with cooling water. The range of flowserve vertical pumps covers wet pit double case submersible slurry and solid handling sump and concrete volute configurations. Their flow rate varies depending on the heat flow to be dissipated. 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.

Smart pumps are also designed to help reduce operating and maintenance costs. 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. Numerous sizes hydraulics and material combinations are particularly well suited for use in applications where uncompromising reliability and.

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. The pumps are usually horizontal end suction split case double suction or vertical turbine pumps. 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. 2 3 cooling towers in healthcare cooling is especially important in hospitals and medical centers.

The major characteristic of the cwp is their high flow. For the tower piping circuit the pump must overcome the piping flow friction loss. Piping condenser cooling tower losses and valves. It must also provide the energy head necessary to raise water from a low to a higher static head level.
