When you need more flow and bigger solids passage, the QBY-50 steps up. With a 50 mm port and 12 m³/h capacity, it handles thicker slurries and larger debris. The 8 mm solids passage means fewer clogs and less downtime.
Design Highlights
The pump works by alternating air pressure between two chambers. Each chamber has a flexible diaphragm connected by a common shaft. As one diaphragm pushes liquid out, the other pulls liquid in. Ball valves at the inlet and outlet keep everything flowing in the right direction.
