WARNING: When disposing of used oil, please observe the relevant environmental regulations.
Due to the design concept, KSVB pumps require very little maintenance under normal operating conditions. The work
required is described in the following sections.
IMPORTANT:
• All work must be done by suitably trained personnel.
• Maintenance or repairs carried out incorrectly will affect the life and performance of the pump and may cause
problems when filing warranty claims.
• The vacuum pump must be switched off and secured against accidental switch-on for all maintenance jobs.
• All work must be done by suitably trained personnel. The following maintenance-schedule shows the regular
maintenance periods for an average use of the pump.
• Unfavorable ambient conditions and/or aggressive media may significantly reduce the maintenance intervals.
MAINTENANCE SCHEDULE CHART
MAINTENANCE JOB FREQUENCY SECTION
Check the oil level Daily 3.1
Check the oil condition Depends on process 3.2
First oil change After 150 hours of operation 3.2
Subsequent oil changes Every 500 hours of operation or 3 months 3.2
Replace oil filter At each oil change 3.2
Replace the exhaust filter If oil mist at exhaust or annually 3.3
Clean the dirt trap Monthly 3.5
Check the anti-suckback valve Annually 3.6
To simplify the maintenance work, we recommend combining several jobs.
3.1 — OIL LEVEL
The oil level should be checked at least once a day. If the oil level is below the “MAX” mark, oil has to be added until the
level reaches the mark. If the oil level is below the “MIN” mark, stop the pump and check it.
The pump’s oil level during operation must always be between the middle and the top edge of the oil-level glass. When
necessary, switch off the pump and add the correct quantity of oil. Overfilling leads to oil losses at high intake pressures.
High oil consumption often indicates that exhaust filters are clogged.
