Wordfik RTOW series roots pump is a non-contact positive displacement vacuum pump that realizes gas delivery through synchronous counter-rotation of two or more symmetrically meshed Roots rotors (impellers) in the pump chamber. It is a core device in the medium vacuum range (10⁻¹~10³ Pa). Its core features are high pumping speed, oil-free design, and compact structure. It is often used as a booster pump in series with a fore-stage pump (such as a rotary vane pump or a screw pump) and is widely used in industrial scenarios that require fast pumping or large-flow gas processing.
Features:
• 100% Oil-Free Operation
• High Pumping Speed and Large Flow rate
• Strong Pressure Difference Resistance
• Low Vibration and Long Service Life
• No Metal Friction, Low Operating Temperature
