Submersible reflux pump of QHB series is developed based on the production technique of submersible agitator.,

Submersible reflux pump of QHB series is developed based on the production technique of submersible agitator. It is a special equipment for the reclamation of the mixer liquids, denitrification, denitridation and nitrogen removal in Class II sewage treatment plant as well as the environments that require short delivery lift and large discharge in the ground drainageProduct Characteristics1. Special design according to the operating mode of short lift and large discharge2. The main equipment employs punching structure resulting in good hydraulic performance and high efficiency3. The intergrated lift design can realize the quick installation underwater.4. Make use of dual mechanical sealing and multiple elecro-mechanical protective function to improve the operationg reliablity.
