RLZ - Anti idling and acid alkali resistant centrifugal pump
Newly upgraded second generation turbocharged centrifugal pump:
Efficient, energy-saving, idling-resistant design
Patent No:ZL201720388469.6
鸿发国际Applicable to: emergency, backup, and auxiliary options. Widely used in petroleum, chemical industry, acid production, alkali production, smelting, rare earth, pesticides, papermaking, electroplating, pickling, wastewater treatment, etc.
鸿发国际• The unique self-cooling shaft seal design will produce automatic cleaning and cooling functions and provide protection during dry operation. The shaft seal will not be damaged within 20 hours of dry operation without water.
• The pump body is injection molded from FRPP and PVDF materials, which has strong corrosion resistance, strong acid and alkali resistance.
• It is a new type of acid and alkali resistant centrifugal pump with simple structure, easy assembly and maintenance, the impeller is integrally formed with smooth flow channels, and is highly efficient and energy-saving.
