Industrial Process Vacuum
Start here when your process needs an oil-free pumping path. Working pressure, required volumetric flow rate, gas or vapor composition, and duty cycle decide how the pump should be reviewed.

Recently Sold Vacuum Pump Reference
A dry screw vacuum pump model should be reviewed at the pressure point where the process needs the required volumetric flow rate. These recent references show tested operating points from finished pumps.

Use these tested points to frame the RFQ. The final review still checks the buyer's working pressure, required volumetric flow rate, gas condition, and operating duty.
SDR Series
When the duty mainly falls between 20000 Pa(a) and 50000 Pa(a), continue to SDR for the pressure boundary and TF, QER, or QGR series routing.
RFQ Selection Path
01
Send approximate values if exact data is not ready yet.
02
Confirm whether the process includes solvent vapor, wet gas, dust, oxygen sensitivity, or corrosive gas.
03
Review operating hours, start-stop pattern, temperature, cooling water, and site safety limits.
04
Check pump size, speed-control option, seals, accessories, and control logic against the actual duty.
Selection Resources

For a dry screw vacuum pump quote, working pressure and volumetric flow rate are enough to begin the first selection review. Process details can be checked during follow-up.
Open guide
Start dry screw vacuum pump selection with working pressure and volumetric flow rate, then send an RFQ so the actual gas condition, duty cycle, and site requirements can be reviewed.
Open guide
Start with pressure and required volumetric flow rate, then confirm inlet gas temperature. Hot gas can change the review around compression heat, rotor clearance, sealing materials, cooling design, and exhaust-temperature limits.

Open guideOur Advantage
Each selection starts from working pressure and required volumetric flow rate, then moves into gas condition, inlet temperature, duty cycle, and site limits. That review helps keep the pump package tied to the process requirement instead of a model name alone.
Our customized sealing structure is designed to keep the screw housing dry and separate the process gas from the lubrication system, reducing the risk of lubricating oil contamination in the gas path.
