DPH Screw Pump

Introduction

Dry screw vacuum pump is a vacuum generating device that produces suction, compression and exhaust by means of two high-precision screw rotors rotating synchronously in opposite directions without contact in the pump chamber. Its core feature is that no working liquid is required for sealing during the entire operation, thus ensuring a clean vacuum chamber.
