Vacuum pump is an important component of the vacuum packaging machine, its installation basically divided into two kinds, one for the built-in A for the external. Built-in generally adopt a single-stage rotary vane vacuum pump, usually external bipolar rotary vane vacuum pump.

General 400 single-chamber vacuum packaging machine commonly used XD-020 single rotary vane vacuum pumps, 500 single-chamber vacuum packaging machine XD-040 pump, there are also some manufacturers to adopt two sets XD-020 pump replace a XD-040 pump to reduce costs, but the XD-020 pump is 2880 rev / min, high speed, relatively rapid wear and shorten life, and XD-040 pump is 1440 rev / min, low speed, torque large, relatively prolonged service life. Another is external, usually 2X-15 two-stage rotary vane vacuum pump, the pump pumping speed, vacuum degree higher than the single-stage pump, generally used for larger production volume, high vacuum degree requirements, or requirements installed outdoors to reduce exhaust pollution.
