一、Product Introduction：

FEATURES：
1.THZW chemical mixed-flow pump is designed according to GB/T13008, the technical index and performance has already reached domestic and international advanced level of similar products.
2.Hydraulic components is designed and precision casted per CFD computer fluid mechanics and module design, with features of wide and smooth runner, high efficiency, good NPSH performance, small axial force, accurate size and good interchangeability.　
3.The flowing-passed components like pump body, inner rotor, pump cover, impeller, distance sleeve, etc, are all made of superior stainless steel or special materials.
4.Three options of shaft seal, double mechanical seal, packing seal and modular mechanical seal. Many materials like SSIC, hard alloy, can be chosen for grinding sealing surface to meet requirments of various working conditions.
5.Changeable directions of pump inlet and outlet.
6.High reliability, diversion air chamber is setted on sheft end to reduce shaft deflection.
7.Water cooling bearing seat.
8.The impeller has good performance of anti-cavitation, can run normally with absolute pressure 0.05MPa.
9.International standard axial coupling pull back design, No need of dismounting pipeline, easier maintenance.
Application: Widely applied to many fields or processes like petroleum, chemical, acid, alkali, rare earth, smelting, pesticides, dyes, medicine, paper making, electroplate, electrolysis, acid pickling, radio, formed foil, research organizations and national defense, etc. Particularly be applicable to delivery strong corrosive medium of flammable, explosive, volatile, toxic, strong acid and alkali, organic solvents and other expensive liquids, etc.
Performance range：diamension: ～800mm, flow: ～7000 m3/h, head: ～18m, speed: 980/1450r/min, working temperature: -20～+120℃, pressure rating: 1.6Mpa
