QBY Air-Operated Diaphragm Pump – Acid-Resistant Plastic

QBY Pneumatic Air-Operated Diaphragm Pump – Acid-Resistant Plastic Construction

The QBY Air-Operated Double Diaphragm (AODD) Pump is a heavy-duty, self-priming pneumatic pump engineered for transferring corrosive, viscous, and abrasive fluids with outstanding efficiency. Built from acid-resistant plastic, this pump is ideal for industrial, chemical processing, and fluid-handling applications where durability and chemical compatibility are critical. No electricity required — it operates entirely on compressed air, making it safe for use in hazardous or wet environments.

Key Features

• Self-Priming Design: Quickly draws fluid without manual priming, reducing downtime and setup effort.
• Air-Operated (Pneumatic): Runs on compressed air — no electrical components, no spark risk, and safe for flammable or corrosive media.
• Acid-Resistant Plastic Body: Constructed to withstand highly corrosive chemicals, acids, alkalis, and solvents that would damage standard pump materials.
• Versatile Flow Options: Available as a centrifugal pump, booster pump, or diaphragm pump — flow rates from 1–40 m³/h and heads from 15–130 meters; custom configurations available.
• Solids Handling: Diaphragm design allows passage of small solids and slurries without clogging.
• Stall-Safe Operation: Will not overheat or burn out if the outlet is closed — simply stops and restarts automatically when pressure is released.
• Low Maintenance: Fewer moving parts than motor-driven pumps; simple diaphragm replacement keeps operating costs low.
• Portable & Lightweight: Compact form factor allows easy repositioning across multiple work sites.

Frequently Asked Questions

Q: What makes the QBY diaphragm pump suitable for corrosive chemicals?

A: The QBY pump features an acid-resistant plastic body and wetted parts specifically designed to resist degradation from strong acids, alkalis, and corrosive solvents. This makes it ideal for chemical processing plants, laboratories, and any application involving aggressive fluids.

Q: Does this pump require electricity to operate?

A: No. The QBY is a fully pneumatic (air-operated) pump that runs on compressed air. This eliminates the risk of electrical sparks, making it safe for use in environments with flammable vapors or wet/hazardous conditions. A standard compressed air supply is all that's needed.

Q: Can this pump handle solids or slurries?

A: Yes. The air-operated diaphragm design allows the pump to handle fluids containing small suspended solids and slurries without clogging, making it versatile for a wide range of industrial fluid-transfer tasks.

Q: What flow rate and head can I expect from this pump?

A: Depending on the selected pump type (centrifugal, booster, or diaphragm), the QBY delivers flow rates of 1–40 cubic meters per hour and heads of 15–130 meters. Custom configurations are also available to meet specific operational requirements.

Q: Is this pump self-priming?

A: Yes. The QBY is a self-priming pump, meaning it can draw fluid up from a lower level without needing to be manually filled before each use — saving time and reducing setup complexity in day-to-day operations.
