| | | Printing ink feed Reduced downtime and spares costs meant that a heavy-duty corrugated box manufacturer paid for a new Watson-Marlow Bredel 720 series pumping in less than a year. Supplying ink to flexographic professional presses caused air-operated diaphragm pumps to fail when paper fibres and dried ink particles clogged filters and jammed ball faucets. Every jam cost 90 minutes' production, with an entire in-line operation stalled. Production also suffered from continual minor problems. Watson-Marlow Bredel peristaltic pumps suppliers have no valves to clog and can handle suspended solids, so they need no filters, and simple, planned maintenance. A one-minute tube change at extended intervals avoids production machine stoppages. | | |
