1、 With advanced hydraulic model and radial direction sectional structure, tie bolt connects suction casing, connecting piece and discharge casing, etc.
2、 With drum disc balancing mechanism and thrust bearing, axial force can be effectively balanced。
3、 The bearing support is steel coasting with cooling fin. With new-type non-metal synchronic oil slinger and constant position and voltage oil cup, the lubricating is further sufficient and stable.
4、 To strengthen rigid axial design, pipe orifice is designed according to API standard triple load. API standard chassis is adopted to ensure safe, stable and reliable operation.
5、 With thickened casing design, it meets 3mm corrosion allowance according to the requirement of API.
6、 With design implemented according to API682 standard seal cavity, packaging mechanical seal.
7、 Direction of inlet and outlet can be randomly adjusted according to the demands of working conditions water-cooling coil pipe or fan cooing can be increased for bearing casing. Inducer can be added to suction inlet or it can be changed into double-suction impeller.
8、 XBB4C-chemical pump, many materials can be selected for flow passage components to satisfy the transportation demands of neutral and strong corrosion medium.
XBB4D- precisely forged centrifugal oil pump, suction casing, connecting piece and discharge casing are precisely forged. Besides, through heat treatment for three times, good processing property is ensured to satisfy application demands under high-temperature and voltage working condition;
XBB4G-boiler feed pump, metal face is used for sealing suction casing, connecting piece and discharge casing. With sliding bearing support at two ends, it passes through cooling of circulating water;
XBB4P-self-balancing type, impellers are back-to-back arranged. Thus, residual axial force can be reduced to the minimum and operation stability can be greatly enhanced;
