KEEPING THE LIFE IN YOUR PUMP—
TECH TIPS FROM THE PROS
Remember to change the oil JB recommends changing oil after every evacuation
and for larger jobs, it may need to be changed a few times Hydrofluoric and
hydrochloric acids and moisture collect in the oil Left sitting in a pump, they act
as an abrasive on internal surfaces, rusting and corroding them
Cleaning and Testing Your Vacuum Pump
One of the easiest ways to spot if your pump is in need of a good cleaning is to
look at the sight glass If the oil looks milky, rusty, or full of debris, then the inside
of the pump is in worse shape (Figure 2)
To clean, start the vacuum pump and allow it to run for about 15 minutes to warm
up the oil Make sure that you have allowed enough working room to safely drain
and capture the oil After the oil has stopped dripping, tilt the pump forward to
remove any remaining excess oil (Figure 3) Let sit for a few minutes and return
the pump to its normal running position Repeat tilting forward Close drain valve
Dispose of contaminated oil properly
Once the oil has been completely removed, stand the pump on the nose of the
cover (Figure 4) and remove either the two rubber feet from the bottom of the
pump or remove pump base (depends on the age of the pump which option
is available)
Next, turn the pump on to the motor end (Figure 5) and remove the 6 socket
head cover screws holding the cover in place (Figure 6) Remove the cover from
the pump and wipe the inside surface with a dry, clean rag The sight glass is more
difficult to clean Try pouring in some solvent and using a pipe cleaner
Next, remove the oil deflector which is held in place with a socket head screw
(Figure 7) Wipe with a clean, dry rag If needed, a wire brush can be used
to clean any discoloration to metal parts (this will not affect the pump' s
performance once the cleaning is complete) Remove the cover seal and clean
cover seal (Figure 8) Wipe the outside of the cartridge' s surfaces with a clean,
dry rag A wire brush can be used on all surfaces including the exhaust valve and
the intake relief valve If they are discolored, they will still perform fine
DO NOT
Disturb the four cartridge bolts or the two smaller hex head screws
(Figure 8). These are the setting screws.
If the intake relief valve set or the exhaust valve set is damaged and needs
replacing, these items can be ordered through your local wholesaler under JB Part
Number PR-18 It is best to replace after completing the cleaning of the cartridge
Pay attention to the order in which they are assembled for correct re-installation
Reassemble the oil deflector (Figure 9) Clean out the channel for the cover seal
with a clean, dry rag and smear some grease into the channel This will help hold
the cover seal in place for reinstallation of the cover If the cover seal seems a little
tight, stretch the seal a little and try again All seals in JB pumps are designed
to be reused Reset the cover in place and replace the cover screws Tighten in a
crisscross pattern Reattach feet or base
Next, return the pump to its normal running position and place where you drained
the oil Open the drain valve, the top port on the intake, and the isolation valve
Have 1/3 cup of clean oil ready Start the pump and pour the clean oil into the
intake port Let the pump run for 5 to 6 seconds and then shut the pump off Drain
the oil, tipping the pump forward (Figure 3) to completely drain Close the drain
valve and dispose of spent oil properly after the flushing is complete
