What is a two-stage rotary vane vacuum pump?

A two stage design has two rotors and vanes. This means that the first stage generates vacuum and the second stage cleans the system, leading to a deeper ultimate vacuum level. As a result, two stage pumps can produce a deeper vacuum than single stage pumps.

What is the difference between a 2 stage and 3 stage vacuum?

While judging the efficiency in single-stage vs two-stage vacuum pumps, two-stage pumps are quite better. The reason is, a two-stage vacuum pump produces deeper vacuums than a single-stage vacuum.
Frequently Asked Question

Do you have any question?

Dual stage pumps have a low vacuum stage and a mated high vacuum stage in one assembly. The high vacuum stage takes in process gas and transfers it to a second, low vacuum stage that compresses the gas to atmospheric pressure, improving the vacuum performance of the pump.

The rotary vane mechanism is simpler, more durable, and more efficient than reciprocating compressors (also called “piston compressors”), and the result is a better machine — one with more uptime, better energy efficiency and cost-effectiveness, higher air quality, and a longer lifespan.

With a two-stage pump, a transfer valve is located at the outlet of the first-stage volute. It directs the water either to pump discharge VOLUME (parallel) position, or to second-stage intake PRESSURE (series) position, depending on the pump performance desired.
