Industrial Process Vacuum

Dry Screw Vacuum Pump

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.

Use Tested Data To Shortlist Your Pump

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.

Tested flow rate
17.8 m3/min
Test pressure
40000 Pa(a)

Series: SDR-TF series. Flow adjustment: Motor speed and configuration are reviewed against the duty point.Selection status: Confirmed reference point

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

Review the SDR rough-vacuum range

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

From Operating Point To Configuration

01

Working pressure + flow rate

Send approximate values if exact data is not ready yet.

02

Gas or vapor condition

Confirm whether the process includes solvent vapor, wet gas, dust, oxygen sensitivity, or corrosive gas.

03

Duty cycle + site limits

Review operating hours, start-stop pattern, temperature, cooling water, and site safety limits.

04

Configuration review

Check pump size, speed-control option, seals, accessories, and control logic against the actual duty.

Our Advantage

Selection Review Before Configuration

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.

  • No operating fluid is used inside the compression chamber
  • Seal and purge details are reviewed when the gas is corrosive, solvent-rich, or oxygen-sensitive
  • Material and coating questions are confirmed against the process gas composition
