1. PRODUCT DESCRIPTION
These operation and maintenance instructions apply to the DESMI Modular S-N Monobloc
pump series. The pumps are available in sizes ranging from 25 to 100 mm on the pressure
flange. The suction flange is bigger than the pressure flange.
DESMI S-N is a single-stage self-priming centrifugal pump with stainless steel shaft,
mechanical shaft seal, and closed impeller.
The pump is suitable for the pumping of clean and polluted liquids with temperatures between
0 and 80°C. With special shaft seal up to 140°C. Max. number of revolutions: 3600 RPM.
The pump has horizontal inlet on the centre line and vertical outlet at the top.
The back of the impeller is equipped with relief blades to reduce the load on the bearings.
Relief holes in the impeller ensure circulation of liquid for the shaft seal and prevent
overheating of the shaft seal during normal operation.
The pump is particularly suitable for the pumping of water in connection with f.inst. cooling of
diesel engines, as bilge pumps, ballast pumps, pumps for irrigation, washing plants, air
conditioning, cooling systems, and sanitary systems, etc. Furthermore, in the majority of
cases where the transport of liquid is required within industry.
