FELUWA MULTISAFE® double hose-diaphragm pumps
for abrasive, aggressive and toxic media

Media with entrained Gas or Air

For the handling of fluids with rather high entrained gases, MULTISAFE® double hose-diaphragm pumps are provided with so-called dead space reducing cylinders, which are fitted to the inside of the hose-diaphragm.

Gas or air, entrained in the conveyed fluid, must be compressed during the pumping action in order to avoid a loss in flow rate.

By means of the dead space reducing cylinder in the primary hose-diaphragm (towards the conveyed fluid), the volume of the fluid chamber is reduced to minimum. Thus, entrapped gas bubbles are automatically compressed and the hydraulic efficiency of the pump is optimised.
