NEW Pfeiffer XtraDry™ 250-1 Piston Vacuum Pump PN PO P01161

The NEW Pfeiffer XtraDry™ is an oil-free vacuum pump, which is based and operates on the piston principle. The Preiffer XtraDry™ model 250-1 consists of two pistons connected in parallel which during each stroke simultaneously take gas in, compress it to atmospheric pressure and eject it to atmosphere. As a dry vacuum pump, the Pfeiffer XtraDry™ 250-1 is ideally suited for your medium-vacuum applications of down to 6 Torr (7 mbar) that involve the need to pump dry, inert and non-reactive gases. It is ideally suited for use in analytical systems and in industrial applications. It can be operated as either a stand-alone pump or as a backing for our compound turbomolecular-drag vacuum pumps and pumping stations.

It can be operated as either a stand-alone pump or as a backing pump for our turbopumps and pumping stations. The Pfeiffer XtraDry™ 250-1 operates absolutely free of hydrocarbons and particulate matter. This avoids contaminating the process or the environment. Unique seal design prevents gas backstreaming within the pumping system. This enables gases to be pumped regardless of their molecular weight. Its automatic standby mode reduces the speed of the pump by more than 30% during operation at near ultimate pressure. This saves energy and increases service life. The XtraDry™ comes ready to operate, without the need for any additional accessories. A do-it-yourself kit makes for simple maintenance. You’ll need a maximum of 30 minutes to change piston seals. This is an Oil-free vacuum pump with pumping speeds of 8.0 CFM. The operating instructions manual in PDF format can be downloaded, by scrolling down to (AVAILABLE DOWNLOADS) below.
