Thomas Small Pumps Characteristics

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.


Advantages of Thomas’ Small Pump Engineering

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.


Your Trusted OEM Pump Partner

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.
