Horizontal Multistage Ring Section Centrifugal Boiler Feed Water Pump DG280-43X4
 
Description

The design and arrangement of boiler feed pumps has a significant impact on overall unit availability. In determining the optimum arrangement of feed-pumping plant, the economic assessment needs to take account of capital costs, capitalised running costs, repair and maintenance costs, and the likely effects of loss of availability. Other constraints which should be considered are:

 

• The need to ensure that failure of a single pumpset does not impair the start-up of the main unit or affect output capability. Standby capacity equivalent to the largest duty pumpset is indicated with a rapid start-up capability, sufficient to prevent the loss of boiler drum level and consequent unit trip.

 

• The need to ensure that the plant is able to operate satisfactorily during and after a large load rejection by the turbine-generator unit. This requires that the drives for the duty pumps and their power supplies must be suitable for this operating condition. Alternatively, a suitable rapid start/ standby pumpset is necessary.

 
Our DG series Horizontal Multistage Ring Section Centrifugal Boiler Feed Water Pump is is a radially split, segmented casing, multistage pump designed with modular interstage components. These identical components can be assembled to produce pumps of varying numbers of stages, hydraulics, materials, and configurations to meet the customer's specific requirements.
 
Applications

* Hot water circulation
* Boiler water feeding on boat
* Power Plant cooling
* Heating factory boosting
* Cooling tower water supply
* Air-coniditioning

 

Features
