7.4.1 Discharge side
- The discharge line is to be kept as straight and short as
possible, in order to avoid performance reduction.
- The diameter must correspond to the rated diameter of the
tube. A larger diameter is recommended in the event of viscous
liquids.
- Do not close or block the outlet since, as it is a volumetric
pump, it would cause the tube to break or an electro-
mechanical overload.

8.1 Lubrication
APY pumps only require a thin film of grease to reduce the friction
between the roller and the outer surface of the tube. No other lubrication
is necessary.
