Pfeiffer HiPace 350 Turbo Pump with TC 400 Drive Unit Conflat CF 6.0 In. Inlet Flange 350 l/s Pumping Speed. PN: PM P070 411 40

Pfeiffer HiPace 350 turbomolecular high-vacuum pumps with a DN100 CF Conflat CF 6.0 inch inlet flange have a pumping speed of 350 liters per second (l/s) and an ultimate pressure of 3.5 x 10^-10 Torr. This Pfeiffer HiPace 350 pump comes with an integrated TC 400 drive unit side-mounted to the pump, and has an ISO KF-16 exhaust foreline flange. The pump can be mounted in any orientation. 24 VDC input power at a maximum of 300 Watts is required. This HiPace 350 turbo pump with TC 400 drive unit has Pfeiffer part number: PM P070 411 40.

The included TC 400 drive unit is a compact onboard controller which includes an RS485 communication interface, a D-sub connector for remote operation, and two accessory ports (to control either an air-cooling fan or solenoid vent valve). For Original Equipment Manufacturer (OEM) and system integration applications, all that is needed to start the pump is a suitable 24 VDC power supply along with start/stop logic. For laboratory applications we recommend the 300 Watt Pfeiffer OmniControl 300 controller which can both supply power and control the pump. The OmniControl 300 is a bench top or rack mountable remote user interface/power source, which communicates with and provides full monitoring and control of Pfeiffer HiPace series turbo pumps through RS485.

We offer a variety of optional accessories, including the OmniControl 300 pump controller, inlet screens, a forced air-cooling kit, water cooling block, water cooling round unit, solenoid operated vent valves, and heater bands (for Conflat CF flanged pumps only).

The Pfeiffer Vacuum HiPace series of turbopumps feature a unique rotor design with proven hybrid bearings. HiPace pumps achieve high pumping speeds and high gas throughput as well as high compression for light gases. HiPace pumps have both turbomolecular and drag stages for improved tolerance to higher backing line pressures and offer enhanced pumping speeds across all gas species. HiPace hybrid bearings are a combination of a ceramic ball bearing on the fore vacuum side and a permanent magnetic radial bearing on the high-vacuum side. This bearing technology does not require electromagnets and has an extended service life with typical maintenance intervals of approximately 4 years. In addition to enhanced performance, all HiPace turbo pumps have field serviceable oil cartridges and shaft bearings which dramatically decreases downtime.

Pfeiffer HiPace pumps with a Conflat CF flange are true ultra-high vacuum (UHV) pumps with an ultimate pressure into the 10^-10 Torr range (if all-metal intake seal gaskets are used and the vacuum chamber is completely cleaned and baked out). Turbo pumps with ISO flanges are limited (by permeation and outgassing of the rubber/elastomer O-ring seals) to an ultimate pressure in the 10^-8 Torr range. The intake of Conflat-flanged HiPace pumps can be baked up to 120 °C if the turbo is water cooled.

About the cooling unit options
The turbo pump comes ready to install water cooling or cooling fan unit to the side of the pump with two banjo bolts, or a third option for a round water cooling unit to be installed at the bottom of the pump with three bolts. The water cooling block and the round unit have push-fit connectors for the supply and discharge hoses (8mm OD plastic hose). The hose connections may be unscrewed and removed to make use of the integrated G 1/8” threads. The radial air cooling fan unit comes with a M12 connector to be powered with the TC 400 Drive. These cooling units can be found in this website with the following P10xxxx numbers:

• Pfeiffer Radial Air Cooling Fan: P1012615 (Pfeiffer part number: PM Z01 374)
• Pfeiffer Water Cooling Block: P103334 (Pfeiffer part number: PM 016 623 -T)
• Pfeiffer Water Cooling Round Unit: P1012609 (Pfeiffer part number PM 026 068 -T)
