HJZ Pump , pump shaft and motor shaft are close -coupled design. In this way , pump length and installation space are much reduced . Close - coupling ensures the alignment between pump and motor : meanwhile , Pump impeller runs in good balance both dynamically and statically , therefore pump would be kept very well in operation ,AS self -pruming sewage pump, HJZ is advanced in structure for its maintenance covers are wear plate. Maintenance covers enable convenient maintenance and cleaning : and wear plate would greatly prolong the whole serivce life.
HJZ pumps are also used for pumping mixtures containing abrasive solids up to a viscosity of 50 mm2/s. They are applied in many fields, such as industry, civil engineering . marine. waste treatment and so on . Different meutral , alkali liquids clean or dirty can be handle by HJZ : liquids mixed with sand , mud or other dolids in suspension ; low viscosity petroleum products : lime milk , caustic soda and waste water resulted from washing cooling , circulation , purification or emergency |
