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. - Page 57 6 Oil level mark ”Minimum” 7 Ground contact Minimum mark Oil level at the oil sight glass Float Fig.4.1 Oil level, oil sight glass and junction box (pump with covers removed) GA02411_002_C0 - 10/2016 - © Leybold...

All work within the pump should be left to suitably trained staff. In this con- text we would like to inform you about practical seminars offered by Leybold in which maintenance, repair and testing of the SP 630 are cov- ered by qualified instructors. Improperly performed maintenance or repair work will void the CE and ATEX conformity and void any warranty claims. -

When disposing of the waste oil observe the applicable environment pro- tection regulations. NOTICE Use only lubricants approved by Leybold. To change the oil, the cover section on the discharge side needs to be disas- sembled, see fig. 4.2 or 4.3. - Page 67 3. Check the oil level once more and remove possibly escaped oil from the bottom trough. 4. It is to be expected that the pump will continue to lose small quantities of oil from the drain openings.
