Double Suction Vertical Pumps
Goulds Pumps announced the release of
four new hydraulic model double suction pumps. The hydraulic range has
flow rates from 1,500 to 60,000 GPM, and heads in one stage from 100 to
600 feet at best efficiency point. This new range complements and extends
the existing product lines.
Integrated into Existing VIT &
VIC Product Lines
The new double suction range was integrated into the existing VIT and
VIC product lines to increase competitiveness by improving NPSH performance,
and reducing overall pump length. The new range is packaged with existing
sump pump products for dirty liquid pumping at larger flow rates, as well
as existing API BB3 products to complete the oil pipeline applications
New high-suction specific-speed designs
enhance the larger condensate pump offering for central power stations.
This enables new product initiatives in larger BB4 and BB5 pump types,
including the Large Vertical Circulating Water Pumps WC-GP series.
Advantages of Double Suction Impellers
Double suction impellers in vertically suspended pumps have two inherent
advantages over the more common vertical turbine pumps with single-suction
impellers. First, double suction impellers require less NPSH than single
suction pumps. This advantage is important in larger pump sizes, particularly
for high-speed pumping applications over 3,500 GPM at 1,800 RPM, because
pump length is determined by NPSH requirements. Second, particularly for
VS2-S pumps, double suction designs can pump liquids with higher suspended
solid concentrations without the bearing wear commonly associated with
vertical turbine pumps.
Applications for this product include Boiler Feed Systems, Condensate,
Ammonia Transfer, Pipeline Booster, Irrigation, and Deep Wells.
