Know the industry

history of oil sealed screw vacuum pump

The first oil-sealed rotary screw vacuum pump in the world was probably manufactured by Quincy Compressor in 1980. In the year 2004, the company expanded the business and built a new factory in Kunshan, China.

In 2010, the company was acquired by the Atlas Copco Group. All compressor and vacuum pump technologies of Quincy were shared with Atlas Copco since then. With this new rotary screw vacuum pump, Atlas Copco dominates the market more than one decade.

In 2019, the founder of Everblue, the most experienced chief engineer of Quincy and Atlas Copco thereafter, decided to start his own career, together with a mature R&D team. Thanks to the highly reliable technology, Everblue is developing fast and successfully today in the enormous Chinese market.

FAQ

Frequent Questions You May Have

For the distributors we provide a warranty of 12 months for the complete system and 24 months for the rotary screw vacuum pump from the loading date issued on the Bills of Lading if it’s shipped by sea.

For other deliveries the warranty starts from the date of shipment from the factory.

Our standard lead time is 4 – 6 weeks. If all components are available in stock, it can be shortened to 2 weeks.

In principle, we sell our screw vacuum pumps only under our own brand. Co-branding could be an alternative for prestigious distributors.

Due to high value of oil-sealed screw vacuum pumps, we accept quantity from one piece for each order.

We’re the most experienced and the best rotary screw vacuum pump manufacturer in China. We’ll ship the pumps through our own company or a professional export company at best cost rate.

We accept wire transfer (T/T) as standard: 30% prepayment and 70% balance before shipment.

A 100% prepayment is preferable if the lead time is less than 3 weeks.
