But also district heating and power plants together with many other industries will profit from using DSL pumps.MaterialsAlternative material combinations such as stainless steel impeller are available. Maximum working tem-perature is 120oC for the standard model.For higher temperatures, please contact DESMI.Detailed installation and operation instructions are supplied together with the pump.DSL pump mounted with a pressure gauge panel. Furthermore, it is possible to supply the pump with a separate priming pump or ejector.50 Hz: 60 Hz:Pressure range: 2-30 mLC ~ 6-100 ftPressure range: 4-45 mLC ~ 12-150 ftCapacity range: 300-3500 m3/h 1300-15000 US gpmCapacity range: 350-4400 m3/h 1500-19000 US gpmTemperature range:With standard mech. shaft seal max. 80oC ~ 176°F.With special mech. shaft seal max. 120oC ~ 248°F.The DSL pumps are high capacity pumps. Up to 4000 m3/h, pressure up to 40 mLCThe DSL pumps are single-stage, double-suction, verti-cal, 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.For more information on Marine & Offshore solutions, please visit www.desmi.comDEFENCE & FUELOIL SPILL RESPONSEINDUSTRY UTILITYMARINE & OFFSHORESpacer Lenght: Center Height: Height:DSL 400 - 430 1400 mm 500 mm 2100 mmDSL 300 - 320 1100 mm 400 mm 1500 mmDSL 400 - 495 1400 mm 500 mm 2100 mmCompact Lenght: Center Height: Height:DSL 400 - 430 1400 mm 500 mm 1400 mmDSL 300 - 320 1100 mm 400 mm 1100 mmDSL 400 - 495 1400 mm 500 mm 1400 mmPROVEN TECHNOLOGYThe construction of the DSL is based on CAD and CAM, and it has been elaborated to make maximum use of the newest CNC processing technology. The outcome is pumps with specific and uniform tolerances, pumps with well-defined performances, at an absolutely attractive price.The pumps are fitted with bearings and mechanical shaft seal at both top and bottom. 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 pip-ing. Significant advantages to the benefit of the service personnel.Production Technology
