The submersible diaphragm pump is a rodless pumping equipment, which can effectively solve the eccentric wear of rods and pipes in the application of inclined wells and horizontal wells; the mechanical movable parts and well fluids are separated by the diaphragm, which can reduce coal powder, sand, and scale. , The impact of special media (CO2, H2S, etc.) on conventional pumps; at the same time, the equipment has higher efficiency, especially for low-yield wells with significant energy-saving effects. Diaphragm pumps used in coalbed methane drainage and gas recovery can realize intelligent, high-efficiency, energy-saving and safe continuous production in low-yield wells with complex well conditions.

The submersible diaphragm pump system includes two parts: ground and underground:

Ground part: control cabinet, electronic pressure gauge, junction box, etc.;

Underground part: diaphragm pump, small flat cable, power cable, drain valve, downhole liquid level pressure gauge/sensor (optional), etc.
