No working fluid or lubricant in pump chamber. Oil‑vapor‑free exhaust – no contamination of process or environment. Clean vacuum.
Optional VFD motor adjusts speed to match actual load, stabilizes vacuum, saves >30% energy – reduces long‑term operating cost.
Special corrosion‑resistant coating available for rotors and pump chamber – ideal for chemical, pharma with corrosive gases.
Non‑contact claw design, no friction between rotors or rotor/chamber. No oil or filters needed – significantly lower operating cost than vane pumps.
Ultimate vacuum down to -0.095 MPa (-95 kPa). Water‑cooled models reach below -0.094 MPa – meets most industrial vacuum requirements.
