• 2-Stage High Vacuum Pump features a two-stage direct drive rotary vane pump for a strong performance-to-cost ratio.
• Oilless Vacuum Pump, Heavy-Duty has the capacity to perform multiple specific gravity tests simultaneously.
• Oilless Vacuum Pump, Economy provides identical vacuum capacity as many standard oil systems but in a cost-effective, oilless pump package.
• Oilless Diaphragm Vacuum Pump/Compressor is a budget, oil-free diaphragm pump ideal for light to medium-duty applications and supplied with gauges, connections, and relief valves.
• Oilless Diaphragm Vacuum Pump, Chemical Resistant is a smaller, cost-effective oiless pump that provides protection against corrosive solvents.
• Diaphragm Vacuum Pump, Chemical Resistant is a heavy-duty, corrosion, and bleach-resistant pump used for mid-range applications and optimized for use with cell culture contamination protocols.
