Kinney Rotary Piston Vacuum Pump KC-15L

Warning: This maintenance check requires trained personnel with PPE!

All moisture as well as other vapors present in the system will be drawn into the pump. Some may be condensed and will collect in the backing stage oil reservoir; contaminating the pump oil and causing poor pump performance.

Proper use of gas ballast will minimize the amount of condensate and reduce the frequency of oil changes.

Change the oil when it becomes contaminated with foreign matter or with chemicals. The period between changes can be best determined by the user for his particular operation.

Drain the oil by removing both drain plugs on the side of the cylinder.

If drain valves are provided, open both drain valves.

To clear all of the oil out of the cylinder, open the pump inlet (suction) to atmosphere. Turn the pump over a few revolutions to drive the oil out of the cylinder.

Fill the pump with oil as directed under the OPERATION section per Filling The Pump With Oil.

Warning: Always wear appropriate safety gear when performing maintenance tasks.

Is the oil level midway on the sight gauge?

If oil level is not midway, adjust accordingly.

If there are changes in the oil level, check for obstructed oil passages.

Drain a small quantity of oil into a clean container and upload a photo.

Any solid or liquid contaminants in the oil?

If contaminants are found, change the oil.

Note: There is no fixed interval for changing the pump oil, since applications vary widely. This can be determined only by experience or deterioration of pump performance. As a minimum, the pump oil should be changed after each three-month operating (not storage or idle) period.

Warning: This maintenance check requires trained personnel with PPE!

Warning: Always ensure the pump is switched off and disconnected from the power source before performing any maintenance tasks.

Check the oil level daily for the first week of operation and weekly thereafter.

Is the oil level about midway on the sight gauge when operating at low inlet pressures?

If there are no changes in the oil level, check for obstructed oil passages.

Are there any obstructed oil passages?

Check the condition of the oil periodically by draining a small quantity of oil into a clean container and visually inspecting it for solid or liquid contaminants.
