Horizontal Ring Section Self-Balancing Multistage Centrifugal Stainless Steel Water Pump DF25-30X4P
Description
DF series self-balancing multistage ring section centrifugal stainless steel water pump is designed to remove the mechanical balance drum, balance disc, balance socket and similar part, but achieve the balancing function by reverse circulation water pipe. Such external bypass piping is designed for water flowing into the end of the pump from the suction side, and then reversely flow back to the discharge section in the middle, which makes the water flowing from both sides of the discharge section. It will balance the axial thrust caused by the high pressure impeller from both sides and escape the mechanical wears out as well as overloaded axial force of the traditional multistage pump, and ensure the stability and endurability of the pumpset.
It is designed to transfer the corrosive liquid like acid liquid, sea water, mining water with corrosiveness , and the pump can handling clean water, hot water, boiler feed water, corrosive liquids, oils, and abrasive medium by use different materials of construction, proper seal type, and external seal flushing plans.
Improved design
Versatile mechanical configuration and a redesigned fire stage suction impeller make it easy to integrate into high pressure applications, with the high suction capabilities needed for rigorous hot water or condensate demands.
Safe operation
Protect your people and reduce downtime with built-in safeguards, such as a large self-cleaning seal chamber for solids handling and a variety of variable frequency drive options.
Energy saving
High-efficiency hydraulics optimized by computational fluid dynamics calculations reduce life-cycle costs and energy usage.
Reduced wear
Elastically supported plain bearings made from tungsten carbide resist extreme vibrations and shocks. A bypass water reverse pipe system reduces axial force rised by impellers.
Easy maintenance
Drive side bearing, mechanical seal and balancing drum sub-assembly are all easily accessible without removing pump from the piping system, and use common parts across the range to simplify spare parts arrangement.
