The Leybold SOGEVAC SV 55 BI² is a single-stage, oil-sealed rotary vane vacuum pump for analytical instruments with a pumping speed of ≥ 36 m³/h at 2 mbar and an ultimate total pressure of ≤ 0.2 mbar. Ehrler & Beck supplies the SOGEVAC SV 55 BI² in four variants with matching accessories, spare parts and service.
The SOGEVAC SV 55 BI² is Leybold's new backing pump for analytical applications with integrated permanent magnet motor and frequency converter. Leybold states up to 50 % lower weight (31 kg), up to 20 % energy savings and up to three years or 24 000 hours of maintenance-free operation. It is controlled by an on/off switch, analog signals, RS 485 or Ethernet; one litre of oil is sufficient, and the oil drain valve and the oil filling port are easily accessible high above the floor.
Nominal pumping speed: 55 m³/h (50/60 Hz); pumping speed: ≥ 36 m³/h at 2 mbar. The pump measures 402 × 304 × 333 mm and weighs 31 kg with oil filling; the noise level is 58 dB(A).
Typical applications
For the analytical series Leybold names, among others, ICP-MS and LC/MS instruments and use as a backing pump for turbomolecular pumps. All pumps have an integrated anti-suckback valve, integrated lubrication with oil return without external oil lines and a low noise level thanks to low rotational speeds.
Variants of the SOGEVAC SV 55 BI²
The SOGEVAC SV 55 BI² is available from Ehrler & Beck in four variants (part numbers 10330040V01, 10330040V02, 10330040V03, 10330040V10). The power consumption below 10 mbar is < 580 W. The variants differ in mains voltage or motor, in the oil filling, in the connections or in the type of control; the table of each variant gives its version.
