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.
