Archimedean Water Screw Pumps are a special type of volumetric pump, able to satisfy users¿ requirements as regards favourable investment and running costs, flexibility and reliability. In these machines, in fact, the flow rate varies automatically depending on how much the screw is submersed. The flow rate can be modified by adjusting the speed without moving its yield too far from the maximum value.
PA Archimedean Screw Pumps are used in wastewater treatment, in drainage and irrigation applications, in the food packaging industry, and generally whenever water (even if containing suspended solids) has to be lifted.
