Petite Screwpump

This all-purpose small screw pump is self-priming and can be run dry.  A perfect pump for filtration because it delivers steady pressure without pulsation. 

Includes a variable frequency drive to control the flow rate. Can transfer liquids of all viscosities.  A helical rotor turns inside the stator and conveys the liquid through mobile compartments which are created by the movement without any centrifuging of the product. Great for pumping liquids that contain some solids.  Easy to maintain and clean.  

Single screw pump made in Italy by Zambelli. 

Also called a Wobble pump, a Mohno pump or a progressive cavity pump. 

G.W. Kent stocks the spare parts.
