How to Clean Your Freeze Dryer's Industrial Pump?

Step 1: Drain the Oil
Remove the drain screw with a hex key to completely drain the oil. Tilt the pump to ensure all oil is removed.

Step 2: Remove the Front Cover
Unscrew the four screws securing the front cover. Use a sturdy hex key for leverage, then carefully remove the cover.

Step 3: Clean the Interior
Wipe the inside with a dry towel, removing any gunk. Clean the cylinder and ensure no water remains. If rust is present, gently clean with a non-scratch sponge.

Step 4: Unblock the Oil Intake Hole
Check and unblock the oil intake hole at the bottom of the cylinder. Use a stick to ensure it's clear.

Step 5: Reassemble the Pump
Ensure the black seal is properly positioned, then replace the front cover and securely fasten the screws.

Regular cleaning extends the lifespan and performance of your pump. Follow these steps annually or when necessary to keep it in optimal condition.
