Self-Priming Centrifugal Pump

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

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 and positive operation.

This priming priciple 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.

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.

MODULAR S/02 Self-priming centrifugal pumps in close-coupled design

This version of the well-known MODULAR S pump meets the requirements for a compact and reliable pump and does not need special alignment. The pump is
connected to the electric motor via a rigid coupling and can be mounted with any standard electric motor. The MODULAR S pump is constructed of standard components and this principle has been further emphasized in the monobloc version.

For optimum flexibility the pump is designed in such a way that only the coupling and the motor flange have to be changed in order to fit the selected electric motor. The monobloc version is equipped with a separate bearing house with only one bearing, and the rigid coupling is mounted on the short shaft.
