• Single Screw Pump is a Positive Displacement pump and actual Pumping elements are Rotor and Stator
• The Single helical Rotor rolls eccentrically in a double threaded helix Stator of twice the pitch length
• A series of sealed cavities 180 degree are created that progress from Suction to Discharge
• The opposing cavities fill and empty simultaneously resulting in a pulsation less flow
• The fluid travels axially with relatively low velocity and minimal agitation
• The Stator is made of a resilient elastomeric material and vulcanized to the stator pipe/tube providing a slight radial interference of the tool steel / Stainless steel Rotor in the Stator
• The elastomer Stator adds abrasion resistance beyond that of conventional rotary pumps
• The particle tends to imbed rather than abrade the elastomer Stator and also allowing deformation to partially accommodate the solid particles
• The compression fit of the Rotor and Stator enables the pump to handle gaseous liquids and low viscosity liquids
• The pressure capabilities of the pump are a function of the number of times of the progressive seal lines are repeated
