This Pfeiffer HiScroll 12 dry scroll roughing/backing pump has a pumping speed of 7.1 cfm (12.1 m³/hr), and an ultimate vacuum of 6.75 x 10^-3 Torr (9 x 10^-3 mbar). It has KF-25 (NW25) inlet and outlet ports. Input of 100-240 VAC, 50/60 Hz, single phase power is required and and the pump has a standard C14 input power connector. The HiScroll 12 pump draws 8A@120VAC (4A@240 VAC) and is extremely quiet at 47 dB(A). This HiScroll pump has internal motor protection and an integrated two-stage gas ballast which allows for pumping of condensable vapours including water, solvents, dilute acids and bases. Maximum dry air or inert gas ballast pressure is 21.7 psi (1500 hPa).

The pump has an onboard inverter controller which allows the pump to be controlled either manually with easy-to-use push buttons, or remotely via RS485 when connected to a Pfeiffer DCU or OmniControl controller, or a user supplied software interface. The pump controller has a standby mode and when active reduces the speed of the pump to 50% of full speed to save wear and tear on tip seals and to increase bearing service life. This Pfeiffer HiScroll 12 dry scroll pump has part number PD S20 000.

About the Pfeiffer HiScroll Series of Dry Scroll Vacuum Pumps:

The Pfeiffer HiScroll dry scroll vacuum pump series consists of three dry and hermetically sealed scroll pumps with a nominal pumping speed of 6 - 20 m3/ h. The pumps are especially characterized by their high performance when evacuating against atmosphere due to their unique features. Their powerful IPM synchronous motors achieve an efficiency that is up to 15% higher than that of conventional drives.

The pumps are also characterized by their very compact design and extremely quiet and low-vibration operation. Therefore, they are ideal for use in quiet working environments, for example on mass spectrometers, research & development institutes or leak detection systems.

The Pfeiffer HiScroll dry scroll vacuum pumps can be easily connected to other Pfeiffer Vacuum products (such as turbopumps or display and control units) as well as to a higher-level external controller, via RS-485 or ProfiNet. The interface enables RPM regulation, situation-specific control of the fan and monitoring of the pump performance. This helps to minimize wear and noise emissions, and ensures longer maintenance intervals.

The integrated two-stage gas ballast and safety valve ensure process-specific and safe operation. The proven quality of Pfeiffer Vacuum components guarantees pump longevity. Easy maintenance enables short service times and the efficient motor helps to reduce electricity costs.

We carry all the replacement parts and rebuild kits to maintain and keep your Pfeiffer HiScroll vacuum pump in peak operating condition. Please see the operating instruction manual in the downloads.
