Miniature diaphragm pump uses a twin-head design

Using an innovative twin-head design, the new Thomas Model 1420 miniature diaphragm pump achieves higher flows than conventional standard diaphragm pumps of the same physical size.

The oil-less Model 1420 pump is designed for applications requiring high-flow in a compact package, especially in the medical and business equipment markets. The pump measures 3.41 in. long, 1.16 in. wide and 2.96 in. high. It weighs 0.485 lbs.

The pump's heads can be channeled in either parallel or series to meet the flow and pressure/vacuum requirements of the application. Flow is rated at 6.0 to 11.0 lpm, when the heads are in parallel configuration, and up to 5.5 lpm in series configuration.

The maximum pressure rating is 1 bar (14.5 psi), and the maximum vacuum rating is 23 in.hg (-777 mbar).

The model 1420 pump is available in both 12 and 24 VDC versions and incorporates long-life EPDM (ethylene-propylene rubber) diaphragms and valves. Viton elastomers are also available.
