17 Drive maintenance
The pump is sealed to IP31 and is suitable for wipe-down cleaning. Do not use sol-
vents, mechanical scourers, strong organic acids, or alkali-based cleaning solutions.
Remove any tubing, detach the pumphead, and wash the pumphead thoroughly with
a mild solution of detergent in water.
Check moving parts of the rotor from time to time for freedom of movement. Lubri-
cate pivot points and rollers occasionally with Teflon lubricating oil.
The pump has a good, broad chemical resistance to inorganic acids, saline solutions,
alkalis, some hydrocarbons and a large number of oils and greases. It is suitable for
wipe-down but not for long-term contact with alcohols. The case may be damaged by
contact with strong acids or strong solvents.
There are no user serviceable parts inside the pump. The unit should be re-
turned to Watson-Marlow or its appointed agents or distributors for
service.
