Horizontal Ring Section Self-Balancing Multistage Centrifugal
Stainless Steel Water Pump DF200-50X4P
Description
DF series Horizontal Ring Section Self-Balancing Multistage
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.
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.
Horizontal centrifugal pumps can be multistage, i.e., multiple
impellers on a common shaft enclosed in the same pump casing. These
pumps generate increased pressure as the discharge of one enclosed
impeller is routed to the suction of another enclosed impeller
within the casing. Enclosed impellers limit the solids handling
sizes of these pumps. In addition, and much like their vertical
turbine counterparts, the efficiency and effectiveness of
horizontal multistage pumps is dictated by the life of the wear
rings and thin, multi-vane impellers.
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.
The Horizontal Ring Section Self-Balancing Multistage Centrifugal
Stainless Steel Water Pump could be applied to different kind of
corrosive liquid transferring & handling by using different kind of
corrosive-resistant material for wet parts, as well as different
kinds of seal plan & seal flushing plans.
