Choosing an industrial vacuum pump

Vacuum Gurus carries three vacuum pump technologies, each suited to a different kind of job. Liquid ring pumps compress gas with a ring of water, so they shrug off wet gas, steam and liquid carryover. Oil-sealed rotary vane pumps are compact and efficient on clean, dry air, and two-stage versions reach deep vacuum for labs and degassing. Rotary screw pumps move large volumes continuously, from oil-free dry screw pumps for clean processes to variable-speed central vacuum packages.

Filter by pumping speed, electrical supply and series to narrow the list, or call a guru with your flow, vacuum level and application and we will match the right pump.

Frequently asked questions

Which type of vacuum pump do I need?

Start with the gas you are pumping. Wet, vapor-laden or dirty gas points to a liquid ring pump. Clean, dry air at rough to medium vacuum suits a single-stage rotary vane, deep vacuum calls for a two-stage rotary vane, and high-flow central systems or oil-free processes suit a rotary screw pump.

How do I size a vacuum pump?

You need the pumping speed in CFM at your working vacuum level, the volume you have to evacuate and how quickly, and anything in the gas stream such as water vapor or solvents. Call 866-203-9939 with those details and a guru will size it for you.

How can I pay, and do you ship nationwide?

We take credit card, ACH and purchase orders, and ship across the USA. Freight is quoted with your order; Kaishan pumps ship free.

Can you beat the price shown online?
