Used- Welch Chemstar 1400N Vacuum Pump

Used-Welch Chemstar 1400N Vacuum Pump. Model Chemstar 1400N. 110 Volts 50/60Hz single phase, 1/3 HP 250 watts. Type: Belt-drive rotary vane mechanical vacuum pump. Application: Rotary evaporation/distillation. Pumping rate: 0.9 cfm. Oil capacity: 0.62 quart / 0.6 liter. Ult. vacuum pressure 0.1 micronMotor speed: 580 rpm. Intake ID (vacuum connection)7/16 inchIntake/exhaust thread size. Belt-driven Vacuum Pump is designed to tolerate harsh chemical contamination. Vital pump parts are corrosion resistant. The large oil reservoir with PTFE surfaces dilutes contamination and the low pump rotational speed lessens friction to reduce operating temperature and chemical effects. PTFE surfaces, fluorcarbon gaskets and seals, Nitrogen purge to cool and degas oil.
