NEWSCO Vacuum" has been designing, manufacturing, and supplying Dry Screw Vacuum Pump & System, Liquid Ring Vacuum Pump & System, and Steam Ejector System in the important processes. Screwstar Dry screw vacuum pump of new technology has been exporting to global markets such as USA, EU, China, India and satisfying local leading companies.

They are doing their best with aiming of providing the best Vacuum Solution to give customer satisfaction based on over 30 years of accumulated various experiences of specialized application & manufacturing know-how and perfect commissioning of company members in Chemical and General Industries.

The dry screw vacuum pumps system operates with two screw rotors rotating in opposite directions. This traps the medium to be pumped between the cylinder and the screw chambers and transports it to the gas discharge. The advanced screw design results in lower electric energy consumption compared to standard screw designs. It also results in a lower heat load of the compressed gas.

Dry Screw Vacuum Pump Chemistar Series

Historically Chemical & Process Industries use steam ejectors, liquid ring pumps, and once-through oil-lubricated rotary pumps to meet their process needs for various levels of vacuum conditions, which generate wastewater and process effluent disposal. Nowadays in order to be compliant with restrictive national and international environmental regulations, to reduce operating costs, to enable easier process control and maintenance, these industries have replaced their existing pumping units with mechanical solutions. Ideally pump welcome only gases and vapors but in such dynamic process environments with various process materials, chemical processes often involve toxic, aggressive, and explosive materials, in some worst cases, liquid and solid carry-over. All protective equipment like filters, flame arresters, and condensers, etc are fitted at both up and downstream of pumps but not sufficient always to overcome potential problems
Chemistar’s are designed to efficiently pass over the minimal level of unexpected by-products and/or carry-overs to protect themselves and minimize process downtime even though it will be never perfect as a mechanical limitation cannot be completely overcome.
