The QBY-80 is built for big jobs. With an 80 mm port and 24 m³/h flow, it moves serious volume. The 10 mm solids passage handles coarse materials that would choke smaller pumps. This is the pump you call when the job is too big for anything else.
Construction and Materials
You can order the QBY-80 in four materials:
•
Aluminum alloy – light and affordable
•
Stainless steel 316 – for corrosive environments
•
Cast iron – tough and wear-resistant
•
Reinforced polypropylene – chemical-resistant and economical
Each material suits different applications, so pick based on what you’re pumping.

Troubleshooting Tip
If the pump runs but delivers little or no liquid, check for vapor lock. Slow down the pump speed to let liquid enter the chamber. Also check if the ball valves are stuck — swollen elastomers can cause this. Switch to a compatible material if needed.
