Maintenance of Carbon Vane Pumps

• Conveying air with high moisture may shorten the pump’s service life. Air with a high moisture content should be avoided. If unavoidable, inspect pump’s parts periodically to prevent pump damage or injury occurred due to corrosion.

• Bearings, carbon vanes and filters are consumable parts with limited life. Please inspect and replace periodically, especially in operations beyond normal ambient operating conditions.

• The inlet filter and the outlet filter must be cleaned at regular intervals, depending on the amount of dust in the air being pumped. Blow out the filter cartridges with compressed air gun from the inside outwards.

• If the filter cartridge is too dirty to be cleaned, it must be replaced. The cartridges can be taken out after the removal of the filter cover (part 30).

• DRT and VRT rotary vane vacuum pumps work absolutely oil free. Do not lubricate with grease or oil under any circumstances. • Radial fan, hood, and motor should be inspected regularly for dirt. Soiling prevents cool air intake and may lead to overheating of the vacuum pump.

• Bearings are pre-lubricated and require no maintenance.
