DF corrosion-resistant multistage pump is for conveying corrosive liquid without solid particle material. Liquid temperature is -20℃ to 105℃. The allowable pressure of the pump inlet should be less than 0.6MPa. Customers can select reasonable material, seal method, structure and motor of pump according to their conveyed medium, consistence, proportion, temperature and pump inlet pressure, etc.
