QYW25-45 Mine Pneumatic Submersible Pump Motor - Blow to rotate blades for drainage of accumulated water.

Due to fluctuations in raw material prices, the specific models and prices may vary. For detailed quotations, please contact our sales staff. Thank you.

Mine pneumatic submersible pumps—head is what matters! No matter how deep the water, it effortlessly tackles a 100-meter head! From low-lying tunnels to high drainage outlets, it "rides the wind and breaks the waves," making accumulated water obediently "climb the slope" and retreat~ The pneumatic vane submersible pump operates with style and efficiency.

The QYW20-25 delivers a water flow rate of 20 cubic meters per hour, exactly what you need. Mine pneumatic submersible pumps are rust-resistant and must not be tilted during operation. When you choose us, whether you ask about head or flow rate, we will patiently explain everything to you. Pneumatic submersible pumps are one of the commonly used equipment in mine construction, so selecting a manufacturer with high quality and low prices is particularly important. "One piece, two pieces, three or four pieces, five or six pieces, seven or eight pieces, nine or ten pieces, countless pieces"—we customize according to your needs.

Product and working principle:

The mine pneumatic submersible pump mainly consists of three parts: the pump body, the air motor, and the flow passage.

1. Pump body part: Divided into upper and lower chambers, with a seal ring in the middle to separate air and water. The seal ring uses spring sealing and utilizes the pressure of air and water to allow high-pressure air and water to enter the inner walls of the upper and lower seal rings, causing them to expand inward for effective sealing.

2. Air motor part: Composed of a rotor, turbine, upper and lower cylinders, bearings, etc. It uses compressed air as power to impact the turbine, driving the rotor to operate at high speed and perform work.

3. Flow passage part: Consists of the impeller, pump cover suction port, pump base, etc. The impeller is installed on the rotor shaft in the lower chamber of the housing. Compressed air is sent in from the air inlet, and the rotor drives the impeller. The water in the impeller is pressed into the housing's water outlet volute under centrifugal force and discharged through the outlet pipe.
