Clean Your Freeze Dryer's Industrial Pump

The industrial pump operates as a robust workhorse, notable for its minimal noise and infrequent oil changes. However, maintaining cleanliness inside the pump is crucial.

Importantly, during freeze drying, ensure that the gas ballast valve on the industrial pump is fully open. This allows sugars and water vapor from the food to exit through the gas ballast, which can significantly reduce the frequency of internal cleanings.

If you notice gunk during oil changes, it's a sign that it's time to clean the inside of the pump.

Below is a detailed step-by-step guide on how to properly clean your industrial pump:

Step 1: Drain the Oil

Begin by completely draining the oil from the pump. Use a hex key to remove the drain screw and let the oil flow out. To ensure all the oil is removed, tilt the pump slightly.

Step 2: Remove the Front Cover

Next, unscrew the four screws that secure the front cover. These screws are usually tight, so you might need a sturdy hex key for better leverage. Consider using a recommended hex key with T handle available from Amazon. Carefully remove the heavy front cover once the screws are loose.

Step 3: Clean the Interior

With the front cover off, use a dry napkin or towel to wipe the inside. Focus on removing any gunk accumulated at the bottom of the cover. Also, wipe the outside of the cylinder. It’s crucial to ensure that no water remains inside the pump, as it operates with oil. If you notice any rust on the cylinder, gently remove it using a non-scratch sponge. Avoid using harsh chemicals or abrasive materials that could damage the pump's interior.

Step 4: Unblock the Oil Intake Hole

Check and unblock the oil intake hole at the bottom of the cylinder, which is crucial for the normal operation of the pump. Remove any gunk blocking this hole. Ensure that a stick can be inserted into the cylinder after cleaning, indicating that the hole is completely unblocked.

Step 5: Reassemble the Pump

Before reattaching the front cover, ensure the black seal is properly positioned and intact. This seal is crucial for maintaining the integrity of the pump. Replace the front cover and securely fasten the four screws.

Conclusion

Regular cleaning helps improve performance and extends the lifespan of your industrial pump. By following these steps annually or when gunk is evident during oil changes, you can keep your pump in optimal condition and ensure it remains a reliable part of your operations.
