Duty and gas ballast
The pump can evacuate from atmospheric pressure, but prolonged high-inlet-pressure operation can reduce bearing life. Gas ballast helps with compatible vapour loads while increasing ultimate pressure. Exhaust to atmosphere within the manufacturer’s permitted conditions; excessive back pressure can shorten tip-seal life.
Installation and maintenance
Specify the matching mains lead, inlet connections and process protection. Keep ventilation clear and plan tip-seal service. Dry compression eliminates sealing oil in the vacuum chamber but does not remove maintenance requirements. The standard and scientific versions have the same nominal vacuum performance.
