Vacuum Pump Models QV2 & QV5
Using clean, fresh, vacuum pump oil is a critical part of achieving the
desired vacuum. Replace the pump oil if it becomes dirty and looks
turbid, or contains water or volatile matter. When replacing the oil, first
thin down the oil by running the pump for 30 minutes with the intake
closed. Stop the pump, remove the exhaust fitting and remove the oil
drain plug, allowing the oil to drain. Run pump for 1–2 minutes with
intake open while adding a small amount of clean pump-oil through the
intake to flush out any residual oil in the pumping chamber. Repeat this
process several times until the pump is clean. Replace the oil drain plug,
and then fill the oil tank through the oil fill access with fresh vacuum
pump oil to the desired level as viewed through the sight glass.
When storing the pump, install the intake and exhaust caps and place
the pump in a dry location.
Only qualified technicians should attempt to disassemble and repair the
vacuum pump. Service performed by unauthorized personnel during the
warranty period will void the pump's warranty. For warranty repair and
replacement parts, please call Bacharach Service at 724-334-5000.
