Leybold SV40BI 960363V01 Rotary Vane Vacuum Pump

Leybold SV40BI 960363V01 (SV 40/65 BIFC) Rotary Vane Vacuum Pump

The Leybold SOGEVAC SV40BI (MPN: 960363V01) is a specialized single-stage, oil-sealed rotary vane vacuum pump engineered for clean-process rough and medium vacuum operations. Equipped with an integrated frequency converter (FC drive) and optimized for low-inlet-pressure duty cycles, this unit provides precise rotational speed control, low acoustic emission, and consistent volumetric displacement.

Originally tailored for analytical instrumentation, electron microscopy, and high-vacuum turbomolecular pump backing systems, the SV40BI operates below 10 mbar continuous intake pressure and features an anti-suckback configuration paired with an integrated oil mist exhaust filtering network.

Features

1. Integrated Variable Frequency Drive (FC): Regulates motor speed dynamically across variable intake pressures, supporting programmable down-throttling to an energy-saving 900 RPM idle mode without ultimate pressure degradation.
2. Low-Vibration Analytical Grade Balancing: Dynamically balanced rotor assembly specifically engineered to prevent mechanical harmonic interference when directly coupled to mass spectrometers (LC-MS, GC-MS) and scanning electron microscopes.
3. Integrated Hydraulic Anti-Suckback Protection: Fast-acting internal isolation mechanism prevents back-streaming of hydrocarbon/ester lubricants into upstream chambers during unpowered shutdown or emergency line trips.
4. High Vapour Tolerance & Internal Gas Ballast: Integrated gas ballast circuit handles condensable solvent vapours, ensuring internal oil clarity and preventing emulsion breakdown inside the pump stage.
5. Low Noise & Compact Envelope: Operates at ≤60 dB(A) with internal exhaust demisters that eliminate aerosol emissions without requiring bulky external silencers.

Technical Details

Applications

• Mass Spectrometry Backing: Primary roughing vacuum backing for LC-MS, GC-MS, and ICP-MS systems.

Frequently Asked Questions

What makes the SV40BI different from a standard SOGEVAC SV40B?

The SV40BI (“BI” designating analytical backing / improved ultimate pressure) incorporates tighter machining tolerances, balanced rotor stages, an internal anti-suckback valve, and an integrated Variable Frequency Converter (“FC”). This allows it to achieve lower ultimate pressure (< 8 × 10⁻³ mbar) compared to general industrial utility pumps while delivering variable speed control.

Can I run the Leybold SV40BI on standard 110V/120V US mains power?

No. The integrated frequency converter on part number 960363V01 requires a single-phase 200–240 V AC supply (50/60 Hz). For operation in 115V environments, a certified 115V-to-230V step-up isolation transformer rated for at least 2.0 kVA must be utilized.

Which oil must be used in the 960363V01 pump?

This unit is calibrated for Leybold LVO 702 or LVO 200 synthetic hydrocarbon lubricants meeting ISO VG 32 standards. Do not use detergent motor oils or unapproved high-viscosity vacuum oils, which will damage the rotary vanes and void mechanical warranties.

How do I clear an inverter trip on the frequency drive?

Disconnect the main line power supply and wait a minimum of 5 minutes for the DC bus capacitors to fully discharge. Check for inlet blockages, verify that the exhaust pressure has not exceeded 1.15 bar abs, inspect the oil level through the sight glass, and re-apply line voltage. If the fault persists, verify motor winding resistance across the phase terminals.

What is the service interval for internal exhaust filter replacement?

Under standard clean mass-spec backing duties, the internal exhaust demister cartridge should be replaced annually or whenever exhaust backpressure approaches 0.15 bar gauge. In solvent-heavy environments, inspect the oil monthly and replace oil mist separators every 6 months.
