Horizontal Multistage Ring Section Centrifugal Hot Water Circulation Pump DG280-43X8
Description
The design and arrangement of Horizontal Multistage Ring Section 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. 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 provision of sufficient pumping capacity to meet flow requirements under all operational circumstances. It is normal practice to include a flow margin to accommodate additional demand by the turbine above its design rating during transient flow disturbances. A margin on pump generated head is also appropriate to cover for deterioration resulting from internal wear during periods between overhaul.
Our DG series Horizontal Multistage Ring Section Centrifugal Hot Water
Circulation Pump is a configured, ring section, multistage pump
specifically designed for high pressure feed service in long
distance water tranferring applications. Its improved hydraulic
performance makes it suitable for any other high pressure
application with clean liquids.
Balancing system
The balancing system consists of the balancing bushing, installed in the discharge casing, and the balancing drum, assembled on the shaft. The system uses the force of the liquid being pumped to reduce load on mechanical seal and wear on the bearings. The complete system can be disassembled for maintenance without removing pump from its piping.
