KPM Square Series Miniature Gas Pumps

DC Power, Pressure to 350 mmHg
DESCRIPTION
The KPMS series pumps incorporate two mini-diaphragms operated by a rocker arm attached to an eccentric on a motor shaft. The function is simple and reliable.

KPMS pumps are remarkably small, with overall length less than 43 mm. In addition to small size and light weight they offer excellent performance considering their very low cost.

KPMS pumps are offered in two models and are only offered for OEM applications. Samples are available for the qualified OEM so that application suitability can be determined.
