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 a unproblematic operation.

This self-priming principle means that the Modular S can pump a mixture of air and liquid and thus evacuate air from the suction pipe.
