Our bellows compressors and bellows vacuum pumps use our unique welded metal bellows technology as the pumping chamber. This allows for features and performance parameters that are impossible to achieve with conventional vacuum pumps and compressors. These products are suitable for use in extreme environments where zero leakage, zero contamination, high reliability, and long life are required. We achieve superior performance with non-wearing wetted surfaces fabricated from corrosion-resistant stainless steels. These are effectively hermetic compressors or hermetic vacuum pumps.

Standard Design Pumps/Compressors
Standard and custom-designed pumps are available with options for high-pressure (<100 psig), low-flow, all-metal valve, VCR® ports, along with various motors, including three-phase, DC, variable-speed, explosion-proof and radiation-resistant options.
Our customer—a large medical equipment manufacturer—required a new design for a precision metering pump for blood analysis sampling. The component was to be used in a disposable cartridge, so relative cost was an issue.
Moving highly toxic gasses from bulk storage to the point-of-use is a perennial challenge for many semiconductor manufacturers. Unfortunately, most conventional pumps rely on seals that are subject to wear—potentially risking harmful leakage and human exposure.
