FQW pneumatic submersible centrifugal pump in mining is safe and reliable. Also it can effectively improve the air quality at site. FQW pneumatic submersible pump is widely applied to any underground mine with gas or coal dust, dangerous explosive working conditions.
FQW pneumatic submersible pump features:
FQW mining pneumatic submersible pump uses compressed air as the driving force and adopts a centrifugal pump structure. It has the advantages of small size, light weight, simple structure and easy installation and maintenance. It is safe and reliable to be used in mines containing gas and coal dust, which is the advanced pneumatic drainage water equipment.
FQW/W series mining pneumatic submersible pump is a breakthrough in the design. It adopts pneumatic turbine to use compressed air as the driving force, and overcomes those drawbacks like loud noise, high air consumption and low efficiency that the conventional pneumatic pump suffers, it is widely used for sewage drainage in mines.
1. Low noise, within 40db;
2. Low air consumption, high efficiency;
3. Small size, light weight, compact structure and portability;
4. Long service life, wear-resistant parts, easy maintenance.
