一、Product Introduction：

FEATURES：
1.TCD no leakage petrochemical multistage magnetic pump is designed accoding to HG/T 2730-2012 and API685-2000.
2.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.
3.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.　
4.Rotating ring, shaft sleeve, sliding bearings are made of SSIC and tungsten carbide material with good characteristic of superior wear resistance and anti-corrosion which guarantee the pump’s working life.
5.New type permanent magnet with good magnetism, high temperature resistant and no demagnetization is selected.
6.The unique automatic axial force balance system, which makes the axial force is almost zero, produce only very minor mechanical friction during long-term running and operation
7.Double sliding bearings structure makes medium flow smoothly.
8.Enclosed static seal completely solves the problem of dielectric leakage.
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 medium of flammable, explosive, volatile, toxic, strong acid and alkali, organic solvents and other expensive liquids, etc.
Performance range：design pressure：1.6-6.4Mpa, flow:2-20m3/h, head：20-400m, power：3-160kw
Applicable temperature：-20～120℃, can be -20～400℃ if using new type material.
The optional accessories: Monitoring of leakage device, monitoring of temperature device, preventive idling running device.
NOTES：Please indicate during ordering if the proportion of medium is larger than 1.3mg/cm3. No idling running. No delivering medium with particles or crystalline.
