Based on many years of experience in the production of self-priming pumps we supply a pump series that meets the future demands for economical and reliable pumps.      REQUEST QUOTE Product information The individual design, compact with a clear-cut cylindrical form, together with the practical advantages such as easy assembling and modular construction of all components ensure a long a trouble-free operation. The success of the DESMI pumps is among other things due to the priming principle which is thoroughly described on the opposite page. This principle means that the modular S can pump a mixture of air and liquid and thus evacuate air from the suction pipe. Thus, priming can be avoided and a foot valve is not necessary.   Various combinations of assembling The pumps of the modular S series can be supplied as free shaft end, mounted on the base plate with petrol or diesel engine, hydraulic or electric motor or in a close-coupled design with electric motor. They can also be fitted with a manual friction clutch and V-belt pulley and with step-up bevel gear ratio 1:2 Applications   Marine pumps:  Bilge pump Ballast pump Fire pump Cooling-water pump Wash-deck pump General service pump   Also suitable for “Contractors” and “Agricultural” use.   Within Aquaculture industry the pumps are suitable for: Freshwater Water with additives Seawater Oils up to 500 cSt   RAS Applications: Scretting Pumps Miscellaneous Industrial pumps:   Ground water pumps Fire pumps Wash-down pumps Cooling-water pumps Circulation pumps Fuel pumps Filling of tanks and wagons Technical data Technical data   Nominal diameter (DN) 32 to 125 Flow rate - 50 Hz Up to 340m³/h (1500 US gpm) Flow rate - 60 Hz Up to 410m³/h (1800 US gpm) Head Up to 140 m (460 ft) Temperature Up to 140°C (284°F) Motor Standard and EX motors VFD Direct or Bulkead/Wall-mounted ATEX approved Yes Pump curves Pump curves 50 Hz PDF   960 RPM   1450 RPM   2950 RPM     JPG   960 RPM   1450 RPM   2950 RPM   60 Hz PDF   1152 RPM   1740 RPM   3540 RPM     JPG   1152 RPM   1740 RPM   3540 RPM   Drawings Drawings DIMENSIONAL SKETCHES   DESMI MODULAR S-N (P. 19)  DESMI Modular S-N Monobloc (P. 21)  DESMI Modular S-N Super Bilge Pump (P.16) DESMI Modular S-N Super Self-Priming Pump in Type 02 (P. 17)   ASSEMBLY DRAWINGS   desmi MODULAR S-N  DESMI Modular S-N Monobloc DESMI Modular S-N Super Bilge Pump DESMI Modular S-N Super Self-Priming Pump in Type 02 3D DRAWINGS   S70 50 175 N A02 DWG IGS STP   S80 70 220N A02 DWG IGS STP   S100 80 175N A02 DWG IGS STP       S100 80 275 N A02 DWG IGS STP   S125 100 220 N A02 DWG  IGS STP Manuals Manuals Modular S-N - Open Design (T1440) English English Danish German French Russia Polish Download Modular S-N Monobloc - Open Design (T1441) English English Danish Russia German Polish Download Modular S-N Super Bilge Pump (T1444) English English Danish Russia German Download Modular S-N Super Self-Priming Pump (T1530) English English Download Brochures Brochures Modular S - Stripping Pump English English Download Modular S English English American Dutch French Danish Download MORE BROCHURES Video DESMI Modular S Centrifugal Pump You must accept cookies to view this.
