QHB Submersible Reflux Pump

Product Description

The QHB series of submersible reflux pumps are ingeniously developed, leveraging the advanced production techniques of submersible agitators. This cutting-edge equipment is meticulously designed for the efficient reclamation of mixed liquids, as well as the crucial processes of denitrification and nitrogen removal, particularly within Class II sewage treatment plants. It is also perfectly suited for environments necessitating short delivery lifts and substantial discharge capabilities in ground drainage projects.
