DSL Horizontal Inline Spacer Version


DESMI DSL Horizontal In-Line Spacer Version

The pump is designed for the high flow capacities up to 17,500 US GPM. Manufacturing shall be horizontal in-line, & single-stage, radially split, double suction centrifugal pump with connecting flanges according to international standards. The design of the suction side provides for a perfect flow, and the inlet is placed in line with the outlet.
The design shall incorporate advanced double-suction, closed impeller with double-curved blades, with a helical pump casing in one casting - resulting in high efficiency and low NPSH-values.     

The pump haft to be designed for mounting with electric motors having different international flange dimensions acc. to DIN, ANSI or JIS. The pump casings shall be made in ductile cast iron GGG40 EN1561-GJL-400/DIN1693 or NiAlBz EN1982 CC333G/DIN17656 for seawater applications.

 

The pump casing shall be equipped with a NiAlBz EN1982 CC333G/DIN17656 replaceable sealing ring. Material of the shaft shall always be of high quality duplex stainless steel AISI329/1.4460. The pumps shall be fitted with bearings and mechanical shaft seal at both top and bottom. This gives a robust construction, designed for trouble-free continuous duty.

The impeller shall be made in NiAlBz EN1982 CC333G/DIN17656 (as standard) or duplex stainless steel AISI329/1.4460both with double-curved blades to ensure low NPSH-values and high efficiency. Shaft material shall be of duplex stainless steel AISI329/1.4460 with a single acting, mechanical shaft seal, which seals off the liquid cavity at the motor shaft.

The pump needs to be equipped with a spacer coupling, which is a combined distance and flexible coupling between drive unit and electric motor. This makes it possible to remove the complete bearing housing with shaft, bearings, shaft seal and impeller – without dismantling the motor or pump from the piping. This represent significant advantages to the end user, who with this pump solution secures his installation trouble free maintenance with minimum down time.

For added efficiency the internal pump casing and impeller can be coated for reduction of friction and thus increase in energy efficiency.

As extra equipment the pump may be mounted with a priming pump of the water ring type, complete with
filter and feed water tank, or it may be delivered with an ejector pump.
