Horizontal 3 screw pump
10 - 1 050 l/min, max. 160 bar | D4 series IMO PUMP

Positive constant displacement, rotary, three screw pump. Flow rate per revolution 9.8 - 307 cm3 in 14 steps. The three screws, the central driven screw – the power rotor – which meshes with the two sealing screws – the idler rotors –
are the only rotating components ot the pump. The axial pressure and friction loads on the pump rotors are hydraulically balanced. The power rotor is positioned axially by the selfcompensated thrust washer arrangement, being part of the hydraulic balancing system of the power rotor.
