Horizontal split case multistage centrifugal pump (API610/BB3) Lift:-1500m Flow:-2500m³/h

Product Overview

1. With axial direction and longitudinal intermediate structure,
   it is not necessary to dismantle outlet pipe for repair. Besides, with cone axis design of coupler end, it is convenient in equipment overhaul and maintenance.
2. Packaging-type mechanical seal is adopted according to seal design of API682 standard. It is convenient in installation and maintenance. The axial compression is free of influences of axial dimensions
   of any connecting pieces. It is not necessary to make adjustment. 3. The bearing frame is a
   steel casting with heat sink, and adopts a new type of non-metallic synchronous oil-slinging ring, which makes lubrication more sufficient and reduces lubricating oil pollution; it is equipped with a special bearing gland to meet the dual needs of oil mist and oil bath lubrication.
3. By optimizing axial structure and selecting ball-ball and sliding-ball and
   sliding-thrust bearing forms, the optimal support can be provided for parts of rotor and the cost for bearing and support system can be maximally reduced. 5. Pipe orifice is designed according to API standard twofold load. API standard chassis is adopted to ensure safe, stable and reliable operation. 6. The forged reinforced rigid stepped shaft (empty section can be used as needed in the future) designed according to the optimization of hydraulic performance meets the power transmission requirements, improves the reliability of the rotor, and conforms to the typical design scheme of API610. 7, With back-to-back arrangement of impeller, pipeline and nockbush can be overall balanced to optimize structural balance axial force. 8 、With double -volute structural form, precision cast impeller can guarantee minimum hydraulic radial force. 9、BB3-standard, single-suction impeller, back-to-back arrangement; BB3D -first-stage impeller with two-suction structure enhances anticavitation capacity and reduces suction specific speed;
