Product Description
OverviewDry Screw Vacuum Pump is composed of a pair of screw rotors meshing in the opposite and synchronous way in the pump casing to form the suction and discharge operations.By using the maintenance-free technology,our screw vacuum pump has fewer problemsabout the difficulty and sealing liquid in the pump housing,screw vacuum pumps can be used to recycle many condensable gases.This featurecan solve the pollution and eco-issues of many vacuum systems such as the steam-jet pumps,slide valve pumps,rotary vane pumps and liquid ring pumps,meanwhilethe recycled materials can create additional economic benefits for clients.
Main charateristics·Wide pumping rate range with direct discharge to Atm.and high ultimate vacuum of 5 Pa with single stage design.
·Easy cleaning and maintenance with N2 purging.
·High strength and stability of screw rotor made of ductile iron.
·No contact and friction between screw rotors with no lubricants and no any waste emission and low energy consumption.
·Anti-corrosive coating wet surfaces fitting for the chemical and pharmaceutical industries.
·Precise dynamic balance of screw rotors with smooth operation having lower noise,smaller vibration and longer service life.
