Secure the pump. Four bores in the feet are provided for this purpose.
When bolting the feet down, make certain that there is no stress or twist
on the pump casing. Stress on the pump can change the close tolerances
between the impellers and the pump casing and may result in damage to
the pump (use washers to equalise).
Since compensation elements must be attached to the flanges on the suc-
tion and pressure sides, the screws for attachment of the feet must always
be fitted and tightened.
Use the following screws:
RUVAC 251/501
:
4 x M 12
RUVAC 1001/2001
:
4 x M 16
3.1.1 Filling in of the Lubricants
The lubricant needed for running the pump is supplied in a separate
container.
Unscrew the oil-fill plug (5.1/4) and add lubricant.
An oil without additives and of viscosity class ISO VG 100 (formerly SAE 30)
must be used for the pump. We recommend the use of our special oils
LVO 100 or LVO 210. As PFPE we recommend our LVO 400. Please consult
us if you intend to run the pump with other oils or special lubricants.
It needs to be ensured that the oil filling levels stated in Fig. 3.2 to 3.5
which apply to switched off pumps (at standstill) are correctly maintained.
The filling level in the oil level viewing glass is dependent on the size of the
pump and type of oil used.
If the oil level is too low, the bearings and gearwheels are not lubricated
adequately; if it is too high oil may enter the pumping chamber or the
pump may overheat.
Clean the oil-fill port and screw the plug back in using a gasket which is in
perfect condition.
The oil-fill port must be sealed air-tight. Entry of air from the outside may
cause oil-containing gas to enter the pumping chamber via the impellers
seals.
