Flow rate of manual diaphragm pump

1Manual diaphragm pumpprinciple
Manual diaphragm pumpFlow rate of manual diaphragm pumpUsed for low head and low flow water lifting operations, it consists of a pump body, inlet and outlet pipes, inlet and outlet valves, diaphragm, and push-pull rod. The pump body can be composed of one or two pump chambers. A diaphragm pump with two pump chambers, with the diaphragm located in the center of the pump body or two separate diaphragms installed on the outside of the two separated pump chambers. During work, the handwheel connected to the diaphragm is manually operated by a person to push the diaphragm in and out of reciprocating motion, causing the volumes of the two pump chambers to alternate between expansion and contraction. When the pump chamber expands, the pressure decreases, the inlet valve opens and the outlet valve closes, and water flows into the pump chamber from the inlet pipe; When the pump chamber shrinks, the pressure increases, the inlet valve closes, the outlet valve opens, and the water in the pump chamber flows out from the drainage pipe. The two pump chambers alternate between suction and discharge, and can lift 0-20 tons of water per hour.

Manual diaphragm pumpIt can not only pump flowing liquids, but also transport some non flowing media, and has many advantages of conveying machinery such as self-priming pumps, shielded pumps, mud pumps, and impurity pumps.
1. Not using electricity, safe and reliable for use in flammable and explosive places;
2. Spacious flow and good performance, allowing for the passage of large particles with a diameter of up to 10mm. When pumping mud and impurities, there is minimal wear on the pump;
3. The head and flow can be infinitely adjusted by hand cranking the speed;
4. The pump has no rotating parts and no shaft seal. The diaphragm separates the pumped medium from the moving parts and workpiece medium of the pump, and the conveyed medium will not leak outward. So when pumping toxic, easily reactive or corrosive media, it will not cause environmental pollution and endanger personal safety;
5. No need for irrigation and water intake, suction lift of 2m, lift of 30m, outlet pressure ≥ 2kgf/cm2;
6. Easy to use, reliable in operation, with simple shaking and stopping of the handwheel for starting and stopping. Even if the pump runs for a long time without medium or suddenly stops due to unexpected idling conditions, it will not damage the environment;
7. The pump has a simple structure and few vulnerable parts. It is easy to install and the medium transported by the pump will not come into contact with moving parts such as the connecting rod. Unlike other types of pumps, the performance gradually decreases due to single damage to components such as the rotor, piston, gear, and blades;
