Excentric screw pumps
Excentric screw pumps are positive displacement rotating pumps which have an almost pulsation-free liquid flow and are ideal for pumping liquids from those as thin as water to those with high viscosity, with or without solids.
The capacity of these pumps is directly proportional to the speed and there is little to no impact made by varying water flow pressures or counter pressures; this makes them ideal for dosing purposes. This type of pump is used for a low shear so the structure of the pumped liquid is only minimally affected.
