The invention discloses an 
axial flow pump with a filtering device. The 
axial flow pump includes a water outlet curve, the left end 
flange of the water outlet curve is connected to a 
pipe A through aflange, the left end of the 
pipe A is connected to a 
pipe B through a 
flange, the pipe B is connected with a pipe C through a 
flange, stainless steel filter caps are in threaded connection to ports ofthe left and right ends of the pipe A, a 
sand filter bag is installed inside the pipe A, microporous 
ceramic filter caps are in threaded connection to ports of the two ends of the pipe B, an 
activated carbon bag is installed inside the pipe B, a 
microfiltration membrane filter cap is in threaded connection to the inside of a port of the left end of the pipe C, a pump body is connected to a bottomopening of the water outlet curve through a flange, a filter shell is in threaded connection to a bottom opening of the pump body, the surface of the filter shell is evenly provided with a circle ofhoneycomb through holes, and the filter shell is connected with a mud blocking plate through a clamp. The 
axial flow pump realizes synchronization of 
water pumping and water purifying, the filtering device is simple and easy to disassemble, convenience is brought to cleaning and replacement, and 
water safety of people is better protected.
