Kinney Rotary Piston Vacuum Pump KC-8

Warning: Always wear protective gear while performing the inspection.

Is the oil level midway on the sight gauge?

If the oil level is not midway on the sight gauge, check for obstructed oil passages.

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

Are there any solid or liquid contaminants in the oil?

If contaminants are found, change the oil.

Has the pump been operating (not storage or idle) for three months?

If the pump has been operating for three months, change the oil.

Sign off on the weekly pump oil inspection.

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

Daily Checks for the First Week

Is the oil level midway on the sight gauge?

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

Weekly Checks After the First Week

Upload a photo of the drained oil in a clean container for visual inspection

Any solid or liquid contaminants in 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.

Warning: This maintenance check requires trained personnel with PPE!

Is the top cover of the oil separator removed?

Is the oil separator cleaned as required?

Is the oil mist eliminator element blocked by foreign matter?

Pump back pressure at inlet to the oil mist eliminator (or the oil fill plug)

Is there mist discharged from the oil mist eliminator?

Is the oil return line installed?

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.
