Two shoes mounted at 180° on a rotating wheel compress successively a reinforced rubber hose that contains a fluid to be pumped.
Vacuum is created as the hose returns to its original position and this causes the suction of the material which is pushed forward by the second shoe.
Particularly suitable to convey dirty liquids, thick and viscous mixtures as well as abrasive and corrosive liquids.
The rotor is supported by the heavy-duty bearings of the gear motor.
The pumps operates with constant lubrication mixture consisting of silicones/glycerine/glycols=
