Pump increases the reliability of solvent evaporators

Published: 3-Jan-2006


Supplier of solvent evaporation technology, Genevac, has switched to BOC Edwards' XDS dry scroll vacuum pumps in its centrifugal evaporators to increase reliability and cut maintenance costs.

Centrifugal evaporators used during drug research to remove solvents from chemical compounds rely on vacuum pumps to improve the process efficiency and to remove solvent vapour safely to a refrigerated cold trap, where it condenses.

The pumps that Genevac previously used required regular topping up with oil, but it wanted to provide customers with a 'fit and forget' system so investigated 'dry' vacuum pumps.

The bearings in BOC Edwards' XDS range are isolated from the vacuum, meaning that no bearings, bearing purges, grease or oil are under vacuum, making the pump virtually maintenance-free.

The XDS10 is used in Genevac's largest unit, the HT-24, and offers a high volume flow rate of up to 10m3/hr. The smaller XDS5, which offers flow rates of up to 5m3/hr, is used in Genevac's HT-4X, HT-8 and HT-12 products.
