QDT Series Submersible Mixer
QDT series submersible mixer is a low-speed push flow mixer. QDT series submersible mixers are widely used in the process of water treatment in oxidation ditch and various biochemical tanks, and can also be used for river freezing and landscape water circulation. The low-speed push flow mixer is composed of a submersible motor, reducer, impeller, and installation system.
Description
QDT series submersible mixer is characterized by small power (1.5-9kw), low speed (34-85r / min), large blade diameter (1100-3000mm), large volume flow field, and wide service range. Designed with a swept-back impeller like banana, it has a self-cleaning function. QDT series submersible mixer is made of polyurethane or reinforced glass fiber reinforced plastics. It has the advantages of a light-weight, high strength, and corrosion-resistant. It has the excellent hydraulic performance to ensure a good damping effect with liquid under a low-speed motion state, so as to create a soft water flow. This series of products not only have the function of pushing and creating water flow but also has the function of stirring.
Structure
Feature
- The impellers are made of elastic polyurethane or reinforced glass fiber reinforced plastics, which can withstand varying loads, and the thrust is evenly distributed to the mixture, so they have the best hydraulic design.
- Flange ype blade positioning is more accurate and reliable.
- The impeller has self-cleaning function, which can prevent impurities from winding and blocking.
- Two rows of independent mechanical seals ensure the long-time and reliable operation of the submersible motor.
- The unique sealing designed for cables avoids the hidden danger of water infiltrating to the cables.
- The high quality one-time lubricated bearings have the designed service life of 100,000 hours.
- High efficiency and long life helical gear reducer.
- The leakage sensor and winding stator over-temperature alarming device are in built.
- All fasteners wetted are made of stainless steel.
Application
QDT series submersible mixers are mainly used for mixing, stirring, and circulating in municipal and industrial wastewater treatment. It can also be used as a flow pushing device for landscape water circulation, which can create water flow by mixing and effectively prevent suspended solids from settling.
