Application of QBY cast iron pneumatic diaphragm pump product

1. QBY cast iron pneumatic diaphragm pump does not require water injection, with a suction stroke of up to 7m, a head of 50m, and an outlet pressure of ≥ 6kgf/cm2;

2. Spacious flow and good performance allow 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 rate can be infinitely adjusted through the opening of the air valve (the air pressure can be adjusted between 1-7kgf/cm2);

4. No rotating parts, no shaft seal, the diaphragm completely separates 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, easily reactive or corrosive media, it will not cause environmental pollution and endanger personal safety;

5. No need for electricity, safe and reliable to use in flammable and explosive places;

6. Can work submerged in a medium;

7. Easy to use, reliable in operation, with simple opening and closing of the gas valve for on-off operation. Even if the pump runs without medium for a long time or suddenly stops due to unexpected situations, it will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it will automatically start and operate again;

8. 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;

9. Can transport viscous liquids (viscosity below 10000 centipoise);

10. No need for oil lubrication, even when idling, it has no impact on the pump, which is a major feature of this pump.

Precautions for using QBY cast iron pneumatic diaphragm pump

1. QBY cast iron pneumatic diaphragm pump has extremely slight vibration, and generally does not require bottom foot bolts.

2. If dirt enters the compressed air, it will affect the normal start of the pump. It is recommended that users install pneumatic triple fittings.

3. When suctioning media that are prone to freezing, a valve should be installed at the inlet of the pump. When the pump is stopped, the valve should be closed first, and then the pump should be turned on for a few minutes until the medium in the pump body is completely drained to avoid difficulty in starting the pump again.

4. When replacing the diaphragm, it is necessary to clean the wrist connecting rod and lead sleeve inside the pump, and do not damage the white PTFE sealing ring. Install it as it is and it can be used.
