The new MK5 series SORB-AC Cartridge Pumps use the well known St 707 getter alloy based cartridges, which feature activation at temperatures as low as 350 °C.
|
 |
The new flange design results in more simple and compact overall pump assembly, with foot print and reliability advantages over the previous series.
Pumps are available on flanges sizes from CF 35 to CF 150. The CF 35 flange pump (GP 50) retains its old style configuration.
Two mounting arrangement are available: in nude configuration or with the optionally water cooled body.
Typical applications are in the field of particle accelerators, synchrotron radiation sources and related equipment, surface analysis systems and other R&D vacuum systems

Cartridge
The cartridge is made by coating the getter alloy onto Constantan strips, which are then pleated in concertina fashion and formed into cylinders to make up the cartridge. For the SORB-AC Cartridge MK5 Type pumps, only cartridges made with ST707 getter material are available.
Pump Body
The optional pump body is a simple double flanged nipple. If desired, the pump can be mounted nude inside the vacuum system to fully exploit its pumping speed. The pump body can be supplied with a water-cooled jacket, even though the water cooling is not necessary for the pump to function efficiently.

Flange
The support flange is a standard CF type flange in which one Special Connector equipped with six conductors for electrical and thermocouple connections is TIG welded.
Heater
The heater consists of a tantalum wire spiral wound on an alumina element supported by a stainless steel rod. The heater assembly also includes the cartridge, the thermocouple positioning (stainless steel tube) and securing components. |
Thermocouple
The thermocouple is a K type electrically insulated within an alumina tube. The thermocouple is assembled on the support flange and connected to the electrical connector with compensated contact terminations
Electrical connector
The Special Connector allows the connection of the pump to the power supply and control unit. The connector is bakeable up to 400°C.
Highlights
- High pumping speed for all active gases
- Constant pumping speed in HV and UHV pressure regions
- No low pressure limitation down to 10-12 Torr
- Reversible pumping of hydrogen and its isotopes
- Operation at room temperature, after activation
- No interference with magnetic fields
- Oil free and vibration free operation
- Low Weight
