Description

The DSL pumps are single-stage, double-suction, vertical, centrifugal pumps. The design of the suction side provides for a perfect flow, and the inlet is placed in line with the outlet.

Short description
The DSL pumps are high capacity pumps, Up to 7400 m3/h with pressure up to 140 mLC at 60 Hz
The pumps are single-stage, double-suction, vertical, centrifugal pumps. The design of the suction side provides for a perfect flow, and the inlet is placed in line with the outlet. Add to this the advanced double- suction impeller and the result is high efficiency and low NPSH-values.

Double volute pump casings ensure less radial force on the pump shaft – hence no radial support bearing or shaft seal required in the bottom of the pump. This gives a robust construction, designed for trouble-free continuous duty. The pumps are radially split. In spacer design, service including replacement of bearings and mechanical shaft seal, can be carried out without removing motor and piping. Significant advantages to the benefit of the service personnel. Furthermore, it is possible to supply the pump with a separate priming pumps or ejector.

Applications

  • District heating/cooling
  • Seawater
  • Water transport or circulation
  • Cooling towers distribution
  • Chiller distribution
  • Scrubber (flue gas cleaning)
  • Aquaculture (Main Pump or Intake Water Pumps)

Ballast and cooling water pumping in the marine industry are also among the many tasks that the DSL pumps solve to perfection.

Materials
Alternative material combinations such as stainless steel impeller are available. Maximum working temperature is 120oC for the standard model.
For higher temperatures, please contact us. Detailed installation and operation instructions are supplied together with the pump.

Options

  • 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.
