Thomas is a leading manufacturer of micro pumps for a variety of industries and applications. Our unique portfolio of micro pump consist of units as small a coin or a paper clip. All of Thomas micro pumps are designed as oil-free modular platforms, and regardless of the technology provide high efficiency and sealed air flow capability.
We provide micro pumps and compressors for pressure and vacuum manufactured in diaphragm and rotary vane technologies. Thomas micro diaphragm pumps are characterized by their operational water vapor tolerance and outstanding chemical compatibility.
The micro rotary vane pumps generate great vacuum at consistent flow rates with minimal vibration and pulsation. Thomas engineers designed the pumps to achieve an excellent size to performance ratio and give you full control over the pump operation.
Thomas is a leading manufacturer of micro air compressors, micro air vacuum pumps, micro compressors, and mini vacuum pumps that can be used in diverse applications and industries. We serve OEMs in various sectors, including medical, laboratory, environmental, and more.

Thomas offers a suite of cutting-edge, versatile micro and small pump technologies tailored to empower you with seamless integration and user-friendly experiences. Our pumps, including micro compressors and mini vacuum pumps, are designed to transform challenges into opportunities across a variety of applications.
Piston Pumps Our piston pumps feature high-quality WOB-L® and articulating piston technologies, providing exceptional performance for demanding pressure and vacuum applications. These micro pumps are widely recognized as some of the most reliable solutions in the industry. learn more about piston pumps technology.
Rotary Vane Pumps Thomas rotary vane pumps, including micro vacuum pumps and miniature vacuum pumps, utilize centrifugal force to compress the volume of the medium, creating pressure or vacuum efficiently. learn more about rotary vane pumps
Diaphragm Pumps Diaphragm pumps operate using a flexible membrane driven by a crank to reduce the volume of the medium. These positive displacement pumps excel at handling both gases and liquids, making them ideal for a variety of industries and applications. learn more about diaphragm pumps technology
Linear Diaphragm Pumps Our linear diaphragm and vibrating armature pumps use electromagnetic forces to power a diaphragm or piston. These smallest vacuum pumps offer precision and efficiency while maintaining compact designs perfect for tight spaces. Learn more about linear diaphragm pump technology
We provide both AC and DC motors with variants, ranging from low-cost DC up to brushless DC, to provide efficient and quiet drives for our pumps. Both our small air pumps and small liquid pumps can work in a series or parallel configuration, thus enabling our customers to replace multiple competitive pumps with one Thomas pump unit in portable or smaller OEM devices.
For the deepest vacuum select Thomas small diaphragm vacuum pumps that provide a flow rate ranging from 0.010 cfm (300 ml/min) to 0.58 cfm (16.5 l/min), and vacuum levels of up to 99% of the local barometer maximum, which translates to 1 mbar abs (29.2 in.Hg).For applications requiring high precision and no risk of cross-contamination we recommend small liquid peristaltic pumps. These pumps are easy to use and maintain, and they offer flow rates ranging from less than 0.1 ml/min to 3,000 ml/min. Special models capable of handling higher pressures of up to 10 bar are also available.
Our state-of-the-art engineering guarantees a sealed air path and proven reliability. We utilize a selection of high quality materials for the pump components based on a chemical resistance to the media being transferred. Our customers can choose from a variety of materials for diaphragm, pistons, valves, and tubings including EPDM, FKM (Viton), Silicone, NBR (Perbunan), PTFE (Teflon), depending on the model selected.
As a leading small pump manufacturer, we provide a level of customization that is second to none on the market with an extensive variety of small pumps consisting of 20 pump series. Combined with the various configurations that we offer, a pump can be selected from over 100,000 unit variations.
