Product Description
QJB Stamped Stainless Steel Submersible Wastewater Mixer

Brief Description
QJB stamped stainless steel submersible mixer features lightweight stamped stainless steel impeller. With superior hydraulic efficiency and low energy consumption, it creates uniform mixing inside biochemical tanks and stops sludge settling. Different from cast iron mixers, its light weight reduces stress on installation frames.

Product Overview
This submersible mixer uses thin-wall stamped stainless steel impeller. Comparing with traditional cast iron submersible mixers, it has lighter total weight and smaller starting load. Power range covers 0.37-4 kW. Fully sealed submersible structure supports continuous mixing in aerobic, anoxic and anaerobic tanks for municipal wastewater treatment.

Working Principle
The watertight submersible motor drives the stainless steel impeller to rotate at high speed and produce steady circulating flow for even distribution of suspended sludge. When coordinated with aeration systems, it cuts total energy consumption and boosts oxygen transfer efficiency.
