QYW25-45 type wind-driven flushing sewage submersible pump 
 1. BQF-Ⅳ pneumatic submersible pumps, FWB35-20 wind-driven submersible pump, QYW QYW20-25/70-60/100-36/25-45/25-70 type of wind-driven water submersible pumps, QYQ type high lift pneumatic Diving pump, BQW type Mine explosion-proof submersible sewage pump 
 2. In the new type of air pump QYQ17-70 is designed based on QYW25-45 type wind-driven water submersible pump. The pump is beautiful appearance, small size, light weight, flow, flow part of the structure with downdraft, semi-open impeller use HT200 material may pass red <= 14mm particles. Sewage capacity, not because of the small solid particles or fibers, blocking the suction side, will not result in inhalation of abrasive medium and premature damage. The overall structure of the pump is simple assembly and disassembly and maintenance easy to move, in the presence of gas and coal dust work surface with absolutely safe and reliable, and equipped with advanced exhaust muffler new, greatly reduces the noise level, measured <= 70db ( A), has greatly improved the working conditions underground use.
