Vacuum Pumps

Vacuum Pumps
Cole-Parmer offers a complete line of vacuum pumps for laboratory, environmental sampling, process and OEM use. From free-standing vacuum pumps to self-regulating pumping systems Cole-Parmer offers vacuum pump technologies to cover a wide range of ultimate vacuum down to 1 x 10-8 mbar (7.5 x 10-9 Torr).

Vacuum Pump Selection Guide

  1. Ultimate Vacuum - The technology chosen for vacuum pressure pump applications is largely dependent on the desired vacuum level:

    Down to 0.3 mbar (0.2 Torr):
    • Diaphragm Vacuum Pumps
    • Piston Vacuum Pumps
    • Venturi Vacuum Pumps

    Down to 2 x 10-3 mbar (1.5 x 10-3 Torr):
    • Rotary Vane Vacuum Pumps

    Down to 1 x 10-8 mbar (7.5 x 10-9 Torr):
    • Turbomolecular Vacuum Pumps
  2. Chemical compatibility - Assess the compatibility of the gases with the pump and any potential problems with the process gas (eg moisture). Cole-Parmer offers many chemically resistant options for highly corrosive applications.

  3. Pumping speed (volume flow) and pressure requirements - Assess the vacuum pump's capability to produce both the required pumping speed (volume flow) and throughput (mass flow) against the process's needs by using the equation Q (gas load) = S (pumping speed) x P (pressure) calculation.

  4. Pump Installation - Including port connections and requirement for ancillary equipment such as a roughing pump.

  5. Pump Maintenance - Including frequency of maintenance cycles and required level of expertise to carry out the service.

  6. Costs - Consideration should not only be given to the initial purchase price of the vacuum pump but also the operating costs, maintenance cycles and cost.

Dry, Water-based, or Oil-lubricated?

Dry Pumps (non-lubricated)
provide a clean vacuum over the entire vacuum range. They require little maintenance and don’t generate any waste materials. However, dry pumps have a higher initial cost. Common dry pumps include diaphragm, piston, scroll, and turbomolecular pumps.

Water-Based Pumps
provide a rough vacuum at low initial cost with minimum main- tenance. These pumps are corrosion resistant. However, they are not suitable for water vapor sensitive systems. The disposal of contaminated water is another concern with these pumps. Common water-based pumps include water aspirator pumps

Oil-Lubricated Pumps
provide high pumping speeds and a wide range of ultimate vacuum at a reasonable price. However, the pumps require routine maintenance and oil changes. The oil may contaminate your vacuum. The pumps also require inlet and outlet filters to protect the pump and the environment. Common oil- lubricated pumps include rotary vane pumps and gear pumps.
