What is a water-free foot pump?

The term "water-sealed vacuum pump" describes the same principle as a water-circular vacuum pump: a rotating water ring forms a closed side between the wing and the body of the pump. So the statements of advantages (humidity, air resistance to dirt, near-heat compression) and limitation (foot not limited by the vapor pressure of the water) apply.

Mechanical pressure increases when the foot needs to be deeper.

When the vacuum needs to be deeper than the level that the water ring pump can, the root pump is usually placed in front of the primary pump. This configuration is used in food vacuum cooling, vacuum drying and some chemical processes, but the pressure pump needs relatively clean gas so there must be a shutter and a protective separator.

Frequently asked questions.

Does the waterproof foot pump reach no depth?

Non-extreme legs are limited by the slightly saturated pressure of water: about 17 mbar at 15 °C and 32 mbar at 25 °C. To go deeper, a two-level pump, ejector or pressure pump is needed.

Can it be used for flammable gas?

Yes, thanks to the close thermal compression and no metal rubbing in the compression chamber, but must choose the appropriate explosion-proof version and protect the liquid level.
