30 520R, 520R2 and 520RE maintenance

Always isolate the pump from the mains power supply before opening the guard or performing any positioning, removal or maintenance activity.

￿As part of regular cleaning and maintenance (and at least every three months), lubricate the pivot points, the follower rollers and the tube guide rollers with Ultra Lube (PA 1240), which is a non-toxic perfluoroether-based grease.

￿The stainless steel pumping rollers run on externally-sealed bearings and are lubricated for life.

￿Check that the pumphead track, rotor, rollers and spring-loaded tube clamps (if fitted) are clean and operating properly.

￿If fluid is spilled inside the pumphead it should be cleaned as soon as possible, as reducing exposure time to contamination will prolong pumphead service life.

￿To clean the pumphead, remove the rotor as described under Rotor removal, above. Flush the pumphead out with water and mild detergent, or suitable cleaning agent. Clean the rotor and rollers in the same way. If specific cleaning agents are required to clean the spillage, consult the general guide to cleaning with solvents below or Watson-Marlow after-sales office before proceeding, in order to confirm chemical compatibility. Note: the pumphead guard, rotor cap and clutch boot should be removed in advance of some cleaning regimes. See the table below. These components are available as spares if damaged.

￿Replace the rotor as described under Rotor replacement, above.
