Hargraves produces a wide range of reliable, long-life air and gas miniature diaphragm pumps, miniature vacuum pumps and miniature diaphragm compressors that provide pressure and/or vacuum for the transport of air, gases and vapors. The BTC, BTC-II, BTC-IIS and CTS Series are made from high performance components that can be interchanged to achieve specific flow, pressure, vacuum and even efficient current draw specifications.

BTC BTC-IIS CTS

Hargraves has earned the respect from industry leading OEMs that require fluidic components to perform “service free” under their demanding real world environments. All Hargraves micro diaphragm pumps , micro diaphragm vacuum pumps, and micro diaphragm compressors incorporate leading edge technologies that offer the following benefits:

Highest Performance/Size Ratio: - innovative and efficient engineering designs enable the BTC Series to push the performance envelope in a lightweight, compact size.

Runs in Hotter Environments: selection of advanced materials and our proprietary elastomer diaphragms and valves allow our pumps to operate in increased temperature environments up to 158 ° F (70 ° C).

Performs Quieter: optimized head, chamber, and flow path reduce noise without compromising performance.

Lasts Reliably Longer: Other miniature diaphragm pump manufacturers require replacement kits to extend life. The proven track of “service free” performance reduces the overall costs for an OEM’s product.

Installs Easily: incorporating the lightweight EZ Mount facilitates simple system assembly while dampening vibration and reducing noise levels.

Lightweight, compact size – Hargraves micro pumps and micro vacuum pumps are designed with a compact configuration allowing designers to minimize system weight and their system size.

Dynamically balanced – All of Hargraves miniature diaphragm pumps, miniature diaphragm compressors, and miniature vacuum pumps are uniquely balanced to minimize vibration and maximize life.

Contamination free – Hargraves takes the necessary steps to assure that our pumps are 100% oil free and contaminants to maintain the purity of your system. Our production facility adheres to very strict guidelines to provide a high degree of cleanliness in product assembly and testing areas.

Versatile Configuration – Hargraves has designed their miniature diaphragm pump components to be interchangeable, allowing Hargraves to tailor the pumps to your application specific requirements.
