    DuoSeal Belt Drive High Vacuum Pump 1402B-01

    Welch DuoSeal Belt Drive High Vacuum Pump 1402B-01

    The Welch DuoSeal Belt Drive High Vacuum Pump 1402B-01  is a high vacuum pump ideal for use with the Shel Lab Model 1465 Series 4.5 cubic foot capacity Vacuum Oven.

    For many applications, Welch Dry Vacuum Pumps will provide drying speeds equal to those of traditional, oil-seal pumps.  This means you can upgrade to a cleaner vacuum pump that is easier to maintain.

    Suitable samples include: Foods (Nuts, Cheeses, Fruits, etc), Cosmetics, wet or surface-coated samples needing moisture dryoff, chemicals drying, solvent evaporation, and many others. If your samples can be processed at 3 torr – 10 torr pressure levels, a dry pump will work well in 0.67 cubic foot, 1.7 cubic foot, and even 4.5 cubic foot capacity Shel-Lab Vacuum Ovens.

    For electronic component bakeout, curing, or other samples requiring pressures of 1-3 torr, Welch Chemstar, DuoSeal (Belt Drive) and Direct Drive Oil-Seal High Vacuum Pumps are excellent choices for all size vacuum ovens.

    DuoSeal Vacuum Pumps are known for their ruggedness world-wide. These rotary vane pumps have large oil reservoirs to dilute contaminants. Low pump rpm to reduces friction and wear while minimizing reservoir temperature to lessen chemical reactivity. Pump can be ordered with an optional exhaust filter to control oil mist.

    Features: Ideal for:
    • Low RPM reduces
    • Fast pump down
    • Large oil resevoir dilutes contaminants
    • Low maintenance
    • Long life
    • Freeze drying
    • Distillation
    • Vacuum drying
    • Neon tube manufacturing
    • Degassing
