DESMI S/11

A further development of the DESMI self-priming centrifugal pump types Modular S and SA

To meet wishes for an improved priming capability, especially when using the pump as a bilge pump, this pump is constructed as a combination of the self-priming standard Modular S pump and a priming pump of the liquid ring type.

Priming Principle

Until now the priming principle has been based on the so-called diffuser principle, this principle is now combined with the liquid ring principle. A star wheel from a liquid ring pump is mounted on the same shaft as the impeller in a separate chamber connected to the centrifugal pump chamber and to the discharge side of the pump.

When the pump is started, the liquid ring pump part and the centrifugal pump part start at the same time. The liquid ring pump, which is designed to draw air, is fully efficient from the moment it is started, as the liquid ring is based on the priming water already in the pump.

The Super-Priming Bilge Pump evacuates effectively and quickly the suction line, and compared to normal self-priming pumps the air evacuating ability is more than 10 times better.
