Watson-Marlow Bredel has launched the 520 LoadSure elements range. This combination of tube element and pumphead provides pressure performance up to 7bar, placing its 520 Series peristaltic pump range in direct competition with mechanical diaphragm pumps. A key feature of the 520 Series pumps and LoadSure elements is that element change-over takes less than one minute, requiring no special skills and can be done by the operator.
