Edwards offers special trade-in discount for Stokes Microvac pumps

 CRAWLEY, UK (29 March 2010) Edwards, the leading global manufacturer of vacuum technology, is encouraging its customers to upgrade their vacuum equipment by offering a special discount to purchasers of new Stokes Microvac 212J or 412J oil-sealed rotary piston pumps when they trade in their existing Microvac or equivalent sized pump.

Stokes Microvac pumps are widely used in a range of industries, including vacuum coating, vacuum metallurgy (including heat treatment and melting), chemical processing and pharmaceuticals. They provide high dependability and productivity combined with minimal maintenance and process downtime, and are considered to be the most efficient, space-saving design available for traditional oil-sealed technology. The new ‘J’ series pumps use less power and utilities than older models, enabling users to reduce costs and their carbon footprint.

“We’re continually improving the design of our Stokes Microvac pump to provide increased reliability and reduced maintenance. Our upgrade offer gives customers an opportunity to benefit from the latest features and a full warranty at a more affordable price without the hassle of disposing of old equipment,” explained Dave Sobiegray, Product Manager Industrial Vacuum, Edwards. “Whether their existing pump will soon be uneconomic to repair or they need a newer model for a different project, the trade-in reduces the cost of upgrading.”

The Stokes Microvac is a self-contained, oil-sealed rotary piston pump, with low rotation and large clearances to achieve a longer life cycle. A new encapsulated valve design, improved ‘O’ ring sealing areas and totally enclosed fan cooled motor ensure lower noise, lower power and extended service intervals for customers. The slow rotational speed reduces wear on the piston and slide components for longer life and offers greater ability to handle particulate applications.

An integral oil distribution system eliminates external piping and provides leak-free operation in a stylised design. The pumping piston is mounted to the main drive shaft via an eccentric and supported by two free oscillating hinge bars. When the piston rotates, air enters the pump through the piston slide. As the piston reaches the top-centre position, the intake port is closed, compressing the trapped air, which is discharged through the exhaust valves and out of the reservoir exhaust outlet as the piston continues to rotate.
