Leybold TRIVAC D8B Vacuum Pump - REBUILT
Leybold TRIVAC D8B Rotary Vane Vacuum Pump - REBUILT
PTB Sales' technicians rebuild pumps to OEM specifications led by a Leybold Vacuum factory-trained mechanic. We also offer repair service for your used vacuum pumps.
The Leybold Vacuum TRIVAC B are oil-sealed rotary vane vacuum pumps. Oil which is injected into the pump chamber is used for sealing, lubrication and cooling purposes. The pump body is assembled from individual parts without sealing components. The parts are pinned in order to ensure easy disassembly and reassembly of the parts. The pumps are equipped either with single or three-phase AC motors. If the requested voltage is not in stock then we will purchase a new motor and split the cost with you. They run on various vacuum pump oils.
Leybold blower packages are available.
