The Triro pump is of the positive displacement axial flow screw type with only three moving parts - a power rotor and two idler rotors.  These three rotors (hence the brand name TRIRO) have accurately machined intermeshing threads which enfold the liquid being pumped and act as seals in relation to each other and to the pump body or sleeve in which they rotate.
