Maintenance

If aggressive liquids are spilled onto the pumphead, the head should be removed and cleaned with a
mild detergent. Remove any tubing from the pumphead, and swing out the crank handle to expose the
rotor retaining screw. Turn the screw anti-clockwise to release the collet and withdraw the rotor from the
shaft. Loosen the track locating screw and pull the track clear.
The same cleaning procedure should be used to limit the build- up of dust (which can become
electrostatically charged and/or heated by friction).
The moving parts of the rotor should be checked from time to time for freedom of movement. Pivot
points and rollers should be lubricated occasionally with Teflon lubricant or FS DuraTech perfluoroether
grease or similar. Available from Watson-Marlow in 10ml syringes part number OG0035.
All pumpheads should be inspected weekly for any damage, and to ensure no debris is present inside
the pumphead or latch mechanism.
Because of the importance of dissipating electrostatic charge the earthing lead should be regularly
checked for signs of corrosion.
