Edwards Group Limited (NASDAQ: EVAC), a leading manufacturer of sophisticated
vacuum products and abatement systems and a leading provider of related
value-added services, has aided a large pharmaceutical company to reduce its
costs and improve efficiencies by supplying them with an order of XDS dry
scroll vacuum pumps. Since installing the pumps, downtime has been
significantly reduced, as have maintenance and servicing costs, and
operational efficiencies have increased.

A large company with more than 400 vacuum pumps at its research and
development centre on the East Coast of USA was looking for a simple and
reliable vacuum pumping solution that would enable it to reduce maintenance

They were previously using rotary vane pumps in their laboratory freeze
dryers, but as oil-sealed pumps they need regular oil changes. The company
also had prior experience of using an Edwards XDS dry vacuum pump on a
laboratory freeze dryer and was impressed by its reliability and performance.

Edwards worked closely to understand the requirements from the pump and
recommended its XDS35i dry scroll vacuum pumps. The XDS range incorporates a
unique dry pumping scroll mechanism that provides a robust and clean pumping
solution for scientific applications.

Dry pumps have no lubricants under vacuum, eliminating the need for regular
oil changes, therefore reducing maintenance and environmental impact. It also
means there is no possibility of process contamination, an important benefit
in high cost pharmaceutical applications.

Alternative pumping technology was also reviewed, but Edwards’ XDS pump
performance and maintenance requirements proved to be superior. Annual
repairs, labour and maintenance for Edwards’ XDS10 and XDS35i dry pumps are on
average three times less than that for oil-sealed pumps.

As a result of installing the XDS dry vacuum pumps in its freeze dryers,
significant savings to maintenance costs, a reduction in downtime and a more
efficient process have all been achieved. The pump’s water vapour capability
has improved drying time on laboratory freeze dryers by 50% and there has also
been a significant reduction of noise and heat in their labs.

“We are delighted with the opportunity of being able to help our client
benefit from the operational and environmental advantages of dry pump
technology,” says Bob Campbell, Industrial and Process Market Sector Manager -
Americas, Edwards. “The patented XDS design means the bearings are isolated
from the vacuum so no bearings, bearing purges, grease or oil are under
vacuum. As a result, the pump is virtually maintenance free and provides the
perfect solution for ‘plug and play’ vacuum pumping in scientific
