How can we make vacuum pump storage?

• If the pump will not work for a long time:
• Drain the water in the pump by removing the plugs on the pump body.
• Fill the pump with some protective oil and turn the pump shaft until all the parts inside the pump are lubricated.
• Close the openings of the pump.
• Store the pump in a closed, clean and dry environment free from frost.
• Protect the pump from vibration.
• Change the protective oil in the pump every three months.
