D, MD, DG, DF Multi-stage Centrifugal Pump

Structural

MD, D, DG and DF pumps mainly consist of four major parts:stator, rotor, bearing and shaft seal;
Stator part; it mainly consists of suction section, middle section,discharge section, guide vane and so on. Those sections are clamped by tension bolts to form a working room. The D pump’s inlet is horizontal and its outlet is vertical; while the DG pump’s both outlet and inlet are vertical.
Rotor part: it mainly consists of shaft, impeller, balance disc,bushing and so on. The shaft transmits power to the impeller to make it work; the balance disc is used to balance the axial force; the shaft is .mounted with a replaceable bearing to protect it.
Bearing part: it mainly consists of bearing seat body, bearing,bearing gland and so on. Both ends of the rotor are supported by two single-Tow roller bearings mounted inside the bearing body. Bearings are lubricated with grease.
