Watson-Marlow 701 - Manual (Page 11)

Lubrication
Use a detergent SAE#10 automotive engine oil. Lubrication is necessary for all moving
parts and rust prevention. We recommend that an automatic air lubricator be installed in
the air line just ahead of the motor.

Automatic lubrication (recommended) - An In-line oiler should be adjusted to feed one
drop per minute for high speed or continuous duty use. Do not overfeed oil as
contamination of the exhaust air may occur.

Manual lubrication - Add 10-20 drops of oil every eight hours of operation through the
inlet port while the pump is shut down.
