Screw pump is usually used to feed centrifuge. Including screw shaft (rotor) and screw shaft bushing (stator). By a special geometry shape of the this two parts, they form pressurize capacity separately. In a result, fluid flows along with shaft, inner flow speed is slow, capacity remains and pressure is steady, no vortex and agitating generated.

BZ screw pump's flow rate can be adjusted, a wide range of different type and viscosity  liquid can be transported.
