Refurbished Leybold Trivac D40B and D40BCS Dual Stage Rotary Vane Pump
The Leybold D40B and D40BCS series pumps are the much-improved second generation of rotary vane pumps from Leybold. Unlike the Trivac A Series which was constructed with the shaft seal riding directly on the shaft, the B series features a shaft sleeve design that reduces repair costs.
For non-corrosive applications, the D40B is a robust pump offering excellent performance. For corrosive duty installations, the D40BCS features more chemically resistant machined part and seals, as well as a full range of accessories to enhance operation including:
- Automatic Recirculation Systems: Capture exhaust oil mist and recirculates in to the pump.
- Chemical Filtration System: Provide onboard filtration of oil for particles, acids and other harmful materials.
- Inert Gas System: Provides and control a Nitrogen purge to the pumps swept volume.
- Electronic Indicator System: Supplies the end user with various indications and warnings.
