5.泵體為蝸殼式、徑向剖分，具有底腳支撐（CQZ型）和中心支撐（CQZH型）兩種形式；
6.葉輪為整體鑄造閉式結構，采用背葉片或密封環與平衡孔組合結構平衡軸向力；
7.通過泵送工藝液體自循環和外接液體強制循環等多種循環方式將泵內產生的渦流熱和摩擦熱帶走，以滿足不同工況介質的輸送。
8. 因結晶、汽化等工況需要時，可帶冷卻或保溫夾套。
9.優化的剛性軸結構設計，具有更佳的撓度指數，使泵的振動值進一步降低。
10.內置滑動軸承采用了大厚度、重載、強推力陶瓷軸承，選用高純度、高耐磨性的碳化硅材料，使用壽命長。
11.內外磁轉子均為全密封式結構，防止泵在腐蝕環境下磁體腐蝕和磁性能的衰退。

1. This series pumps are all single stage, single suction, horizontal cantilever (type OH1) centrifugal pumps.
2. These pumps adopt axial horizontal suction and radial vertical discharge.
3. These pumps have wide model spectrum range and many product performance parameters that can be selected.
4. Optimized hydraulic model design and anti-cavitation design of impeller with relatively high hydraulic efficiency allow low cavitation margin and reliable equipment reliability.
5. Pump body adopts volute type, radial splitting, and bottom feet support (CQZ) or central support (CQZH).
6. The impeller adopts a closed structure of integral casting, and a structure combining rear blade or seal ring with balance hole to balance axial force.
7. Eddy flow heat and friction heat generated in the pump is taken away by various circulation modes, e.g. pumped process liquid self-circulation and forced circulation of externally connected liquid, to satisfy conveying of media under different operating conditions.
8. Cooling or thermal insulation jacket can be provided if required by operating condition such as crystallization or evaporation.
9. Optimized rigid shaft structural design provides better deflection index, further reducing pump vibration.
10. Internal sliding bearing adopts thick, heavy duty, strong thrust ceramic bearing, and high purity, high wear resistance silicon carbide material, thus allowing long service life.
11. Both internal and external magnetic rotors adopt fully sealed structure, thus preventing pump magnet corrosion in corrosive environment and deterioration of magnetism.
12. Roller bearing is lubricated by oil, with the oil level controlled by both oil gauge and oil cup. This oil cup can automatically compensate the oil level.
13. Lengthened flexible membrane type coupling is adopted. For maintenance, parts such as impeller and shaft etc. can be removed without dismantling the suction pipeline or discharge pipeline.
14. The pump and the motor are installed on the same pedestal.
15. Flange standard may be ANSI, HG/T20615, or HG/T20592.
