Hydro Prokav's Pumping Principle involves the use of a precision - manufactured Metallic Single Helical Rotor which turns inside a double Internal Helical Resilient Stator. It therefore forms cavities confined by a 'Sealing Line'. The sealing line is maintained when standstill, as well as in motion. The cavity created between the rotor and the stator during rotation moves from suction to delivery side, carrying the medium safely.
