4 Operation
4.1 Start-up
The pump must only be commissioned by trained staff.
4.1.1 Oil Filling for the Gear
The SP 630/SP 630 F is supplied without oil in its gear. Before commis-
sioning, the separately supplied gear oil must be filled into the gear.
When doing so make sure that all aids used are clean so as to avoid con-
taminating the oil.
Use only lubricating oil which has been approved by Leybold.
The gear oil should be filled in at room temperature. At lower temperatures,
the oil is thicker so that there then is the risk of overfilling gear chamber
with oil.
For filling in oil, the cover section on the discharge side must be disassem-
bled see fig. 4.2 or 4.3. For this unlock the closure screws at the cover and
remove the cover section(s).
For the closure screws you will require a special square key. This key is
included in the delivery.
Remove the oil fill plug and fill in the lubricant. When doing so, make sure
that the oil level, after filling, will be at the level of the maximum mark (see fig.
4.1).
The total oil filling quantity is 15 litres. Since after the test run and after having
drained out the lubricant some oil remains within the pump, approximately
only 12 litres of oil are filled in during first-time commissioning and when
changing the oil.
Overfilling the gear chamber can result in leakages through the drain and also
into the pump chamber.
Clean the oil fill port and screw the oil fill plug in again using a gasket which is
in perfect condition.
The oil fill port must be sealed air-tight.
For checking the oil level and for changing the oil see Section 5.1.
When switching the pump on and off the oil level may fluctuate visibly. During
operation of the pump the oil level will be between the maximum and the
minimum mark. As soon as the oil level during operation of the pump drops
to the minimum mark, oil must be topped up
After having filled in the oil, the cover must be fitted once more.
The two cover sections are fitted in the reverse order. While fitting, the pegs
at the cover sections must engage into the corresponding bores. This will
ensure that the cover sections are properly seated and, moreover, otherwise
the covers cannot be properly fitted.
