DESMI Modular S

The series of DESMI MODULAR S pumps represents one of the most distinctive products of self-priming pumps.

On the basis of 50 years of experience in the production of self-priming pumps Desmi have produced a pump series that meets the future demands for economical and reliable pumps.

The industrial design, compact with a clear-cut cylindrical form, together with the practical advantages such as easy assembling and modular construction of all components secure a long and unproblematic operation.

The success of the DESMI pumps is among other things due to the priming This principle means that the MODULAR S can pump a mixture of air and liquid and thus evacuate air from the suction pipe. By this, priming can be avoided and a foot valve is not necessary.

The DESMI Modular S series comprises totally 33 types of which 15 types are now available and the series will be successively extended.

A data sheet with dimension sketch and details of capacity and delivery head at different revolutions with NPSH-values for each pump type can be obtained from us.

The pumps of the Modular S series can be supplied with free shaft end, in close - coupled design with electric motor or mounted on a base plate with petrol or diesel engine, hydraulic or electric motor. Furthermore, they can be fitted with manual friction clutch and V-belt pulley and with step-up bevel.

DESMI Modular S Priming principle The priming is based on the diffuser principle, which means that the priming ability is independent of valves and other mechanical elements as it is the flow of liquid that carries the air.

DESMI Modular S -a theme in modular construction

Irrespective of size and capacity the whole Modular S series is constructed of 5 standard

• pump casing
• impeller
• bearing housing
• suction cover
• shaft seal cover

The standardization of these 5 components aids a minimum stockholding as some of the components are common to the different pump sizes. Furthermore, this standardization means low production costs from which you will benefit in the form of competitive prices.
