Maintenance and Servicing
When maintaining these units and having such situations where personnel could be hurt by moving parts or by live electrical parts
the pump must be isolated by totally disconnecting the electrical supply. It is imperative that the unit cannot be re-started during
the maintenance operation.
Do not maintain a pump that is at its normal operating temperature as there is a danger from hot parts or hot lubricant.

weekly. The oil pot may be topped up when the units are in operation. The oil level in the two end cases however can only be topped up when the
units are switched off and vented to atmospheric pressure.
The oil in these two chambers should be changed after 5000 operating hours under normal ambient conditions (see oil drain screws (K
The oil in the oil pot does not require complete changing only topping up. If however this consumption is excessive it will be necessary to change
the shaft sealing rings and the shaft wearing sleeve.
The viscosity must correspond to ISO-VG 100 according to DIN 51 519.
The recommended Rietschle Oil type is: synthetic oil SUPER-LUBE 100 (see oil type plate (M)).
If the oil brand is changed, the old oil must be drained completely from the oil chambers.
Old and used oil must be disposed of corresponding with the relevant health, safety and environmental laws.

3. Protection mesh (optional extras)
The capacity of the pump can become reduced if the air
protection sieve is not maintained correctly.
The protective mesh must be cleaned regularly depending upon the
amount of contamination.
For this the suction pipe to the Roots pump must be removed.
