LUBRICATION
NAVCO recommends the use of an oil mist type lubricator with NAVCO Pneumatic Piston Vibrators. It is important that the lubricator
be properly selected for the operating conditions of the vibrator. Contact your NAVCO sales representative for help with selecting the
proper lubricator.
The oil mist lubricator, when used with the vibrator, should be installed using an air hose of approximately 5 ½ feet connected directly to
the vibrator. The hose connection prevents excessive vibration from being transmitted to the lubricator.
NOTE:
The lubricator should not be mounted on the structure or device to which the vibrator is mounted. The lubricator should
be installed at the same height as the vibrator or higher to ensure that the oil remains atomized in the air stream and is delivered
completely to the vibrator.
Before initial start-up of the vibrator, it is recommended to disconnect the hose from the lubricator and directly insert lubrication fluid
into the hose. This will ‘prime’ the vibrator with oil at start-up.
The oil mist lubricator should be set to 5 drops of lube per minute for every 8 SCFM (with a minimum of 5 drips per minute). After the
vibrator has run for roughly five minutes, a simple check will help determine if the level of lubrication is sufficient. Place your hand about
1 inch from any exhaust port on the vibrator for 8 to 10 seconds. A fine film of oil should be deposited on your hand. If not, increase the
‘drops per minute’ on the lubricator until this condition occurs.
A sight glass is normally provided on the lubricator to indicate the level of lubrication fluid in the lubricator reservoir. This sight glass
should be checked periodically and refilled as required.
*THE VIBRATOR SHOULD NEVER OPERATE WITHOUT LUBRICATION*
A high-duty, low viscosity, low sludge residue, air percussion tool ISO 32 lubricant or 5 to 10W oil is the preferred lubrication for NAVCO
Pneumatic Vibrators.
All NAVCO vibrators are pre-lubed using Royal Purple Synfilm 32 during factory testing. Royal Purple Synfilm 32 lubricant is suitable for
operating temperatures from -75° to 500°F.
We highly recommend Royal Purple Synfilm 32 or equivalent 10W oil.
