Diaphragm pump metering pump in stock

Using specially designed and processed flexible diaphragms to replace pistons, reciprocating motion is achieved under the action of the driving mechanism to complete the suction and discharge processes. Due to the isolation effect of the diaphragm, the electric diaphragm pump truly achieves the isolation between the measured fluid and the driving lubrication mechanism in terms of structure. The high-tech structural design and selection of new materials have greatly improved the service life of the diaphragm. Coupled with the excellent corrosion resistance of composite materials, diaphragm metering pumps have become the main pump type in fluid metering applications.

Diaphragm pump metering pumpFeatures:

1. No need to lubricate with oil, even when idling, it has no effect on the pump.

2. No shaft seal, no leakage, spacious flow channel, no shaft seal diaphragm to separate the pumped medium from the moving parts and working medium of the pump, and the conveyed medium will not leak outward. So when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety, with high viscosity (viscosity can reach 10000 centipoise),

3. The head reaches 50m, the electric pump reaches 30m, and the outlet pressure can reach up to 0.6mpa. The head and flow rate can be infinitely adjusted through the opening of the air valve, and the air pressure can be adjusted between 1-7kgf/cm2. Electric pumps do not have this function and require the installation of regulating valves for control.

4. No need for irrigation, strong self-priming ability, suction range up to 7m, long-term dry breathing, no damage to the pump. Once overloaded, the pump will automatically shut down, and when the load returns to normal, it can automatically start running with self-protection function (electric pumps do not have this function).

5. No power supply required, more suitable for medium transportation in flammable and explosive environments. The QBY pneumatic diaphragm pump has a wide flow barrier and good performance, allowing it to pump flowing liquids and transport some non flowing media. It has many advantages over conveying machinery such as self-priming pumps, submersible pumps, shielded pumps, mud pumps, and impurity pumps.

6. It can work immersed in a medium without power supply, safe and reliable (electric pumps do not have this performance).

7. The pump has a simple structure and few vulnerable parts. It is easy to install and maintain, and the medium transported by the pump does not come into contact with moving parts such as the valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of components such as rotors, pistons, gears, and blades.

8. Easy to use, reliable in operation, the pump can be started and stopped simply by opening and closing the gas valve. Even if it runs without medium for a long time or suddenly stops due to unexpected situations, the pump will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it can start running automatically again.

9. No rotating parts, good performance, allowing for the passage of large particles with a diameter of up to 10mm. The liquid flows without shear, and the wear of the pump's own components is minimal. It has minimal damage to the transported material and can transport sludge and living organisms such as small fish fry.
