The air pump is a vertical structure with a closed impeller. When working, the pump is partially submerged, and the motor is partially above the water. Implementation standards: MT/T315-92, Q/XQK001-2021. Compact structure of air pump, easy to move, install and disassemble, maintenance. Air pump adopts high efficiency and energy saving hydraulic model, special impeller design, with strong sewage discharge capacity, large flow, high head advantages. Suitable for drainage in places with gas and coal dust explosion hazards,

FQW type pneumatic submersible pump body vortex adopts high efficiency and energy saving hydraulic model, impeller is specially designed, it has strong sewage capacity, will not be blocked by the inhalation of solid particles or fibers, and will not be damaged prematurely by the inhalation of granular media, good performance and low air consumption.

It can be widely used in any operation surface of coal mine to transport groundwater containing coal powder and sediment particles, which is safe, reliable and can effectively improve the air quality on site.

1, the pump should be able to work normally under the following environmental conditions: a) surrounding air contains gas and coal dust; b) The air pressure is (0.4 ~ 0.7) MPa; c) The pH value of water is in the range of 6 ~ 8; d) The volume ratio of solid impurities in water does not exceed 2%; e) Working ambient temperature (5 ~ 40) ℃.
