The CLAS HU 0639N is a pneumatic oil pump with a 3:1 pressure ratio, designed for use with 180-220kg oil drums. It is intended exclusively for lubrication tasks. Proper operation requires a compressed air supply between 6 and 8 bar and the use of a pressure regulator to ensure air quality and pump longevity.
Safety instructions
- Always wear appropriate personal protective equipment (gloves, goggles, coveralls, etc.).
- Never allow the liquid to come into contact with exposed skin to avoid injury or burns.
- Do not exceed the operating air pressure range of 6-8 bar.
- Do not exceed the drum capacity specified.
- Always disconnect the air supply and release residual pressure from the gun after use.
- Do not weld above the oil drum.
- Use only on flat surfaces to ensure stability.
Operation
Before connecting the air supply, verify that your compressor provides a stable pressure between 6 and 8 bar. Connect the air coupling to the inlet nozzle. The pump will activate until the hose is fully primed with oil. Once primed, pull the gun trigger to begin lubrication. If a pressure regulator is not used, you must manually lubricate the pump daily with grade 10 oil through the air inlet.
Maintenance
- Clean the pump daily.
- Inspect the hose and all connections daily for leaks or damage.
- Do not use aggressive cleaning agents like fuel or solvents, as this will void the warranty.
- Use only original spare parts for any repairs.
- If the pump is no longer functional, it must be disposed of according to local environmental regulations.
Troubleshooting
If the pump runs but no oil is dispensed, check for foreign bodies in the piston; clean or replace the O-ring. If the pump fails to start, check the air inlet and ensure the piston is not stuck. If the pump does not stop when the trigger is released, the valve may be faulty and require replacement. If the flow rate is insufficient, clean the gun nozzle with air to remove obstructions.

Practical help
Common problems
Pump runs but no oil is dispensed
Check for foreign bodies in the piston; clean or replace the O-ring.
Pump does not work
Check the air inlet; if the piston is stuck, move it up and down. Inspect plastic clips for damage.
Pump does not stop when trigger is released
The valve is likely faulty; replace the valve.
Insufficient oil flow rate
Remove the nozzle from the hose and clean the gun with air.
Before use
- Verify air compressor pressure is between 6 and 8 bar.
- Ensure a pressure regulator is installed (recommended).
- Wear appropriate safety gear (gloves, goggles, etc.).
- Check that the oil drum is not empty.
- Ensure the pump is placed on a flat surface.
Specs in practice
- Pressure Ratio 3:1
- The pump increases the input air pressure by a factor of 3 for oil delivery.
- Operating Pressure 6-8 Bar
- The required air pressure range for safe and efficient operation.
- Drum Capacity 180-220kg
- The compatible size range for oil drums.
Images and diagrams
- The exploded view shows the internal components of the pump, including the piston, valves, and seals, which are useful for identifying parts during maintenance or repair.
Model compatibility
- Designed exclusively for lubrication work.
- Requires a compressor capable of continuous operation at 6-8 bar.
