Motor Driven Diaphragm Pumps

Sigma/ 2 Series


New Technology, Durable Design

The ProMinent® Sigma/ 2 is a mechanically-actuated diaphragm metering pump capable of flow rates from 14.8 to 111 gph (56 - 420 l/h) and pressures up to 232 psig (16 bar). The entire Sigma motor-driven metering pump product range, control type S1Cb/S2Cb/S3Cb, has been equipped with intelligent features to provide a high level of operating convenience, safety and efficiency. The Sigma X features a removable HMI control unit with innovative click-wheel and 4 operating buttons. Also available in basic (non-microprocessor based version) and explosion-proof models.
