Horizontal Multistage Ring Section Centrifugal Boiler Feed Water
Pump DG150-30X6
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 provide adequate NPSH margins, taking into account that the pumps are supplied from a direct contact heater (de-aerator), which can be subject to pressure decay following a reduction in turbine load.
• There should be at least two pumpsets capable of starting the unit. If a turbine drive is to fulfil this function, then a steam supply independent of the main boiler (i.e., an auxiliary boiler) is required.
• If two or more pumps are required to operate in parallel, then the pumpsets should be able to accommodate run-out duties following loss of an operating pump.
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
Suction and discharge casings
* provide flexibility for customer piping layout.
* radial and end suction configurations are available for the
suction casing.
* discharge casing is dual volute type.
* radial suction casing and discharge casing can have nozzles
positioned in 90O increments to allow customer flexibility in plant
layout and equipment location.
