Horizontal Ring Section Multistage Centrifugal Hot Water Circulation Pump DG25-30X8
Description
The DG series Multistage Ring Section Centrifugal Hot Water Circulation Pump is a radially split, segmented casing, multistage pump designed with modular interstage components.
It is specially designed for hot water and boiler feeding projects. Industrial boiler feed water pumps, for example on board a marine vessel, in a large industrial factory or power plant, are fed either fresh water or steam by a high pressure boiler feed pump. As the water or steam is fed round a system, they are sometimes referred to as boiler circulation pumps. Multiple impellers are used in series to generate the high pressures necessary to feed the boiler.
The design and arrangement of Horizontal Ring Section Multistage Centrifugal Hot Water Circulation Pump 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.
Liquid handling requirements have evolved over the years and have increased along with temperatures and pressures. Today’s installations demand sturdy but quiet, smooth running pumps with longer life cycles. These modern pumps with a clean, straightforward and updated design were developed with upgraded materials of construction and a simplified offering without limiting ranges and keeping maximum interchangeability in mind. These pumps not only feature shared hydraulics and premium materials as standard offering, but also offer industry leading durability.
Balancing Device
The balancing device on centrifugal pumps is designed to fully or partially compensate axial thrust generated by the pump rotor. Designs incorporating a single balance drum or double drum require a thrust bearing to absorb the residual thrust.
When the pump is in operation, the balancing device requires a certain amount of balancing flow through the clearance gap between the balancing device's rotating and non-rotating parts. The balance flow is subjected to considerable throttling on its way through the gap.
This pressure loss results in an axial force acting upon the balancing device which counteracts the impeller's axial thrust and effects the required balancing. Balancing devices are used when the axial thrust involved is extremely high, as is the case with super pressure pumps.
