New Technology, Durable Design
The ProMinent Sigma/ 3 is a mechanically actuated diaphragm metering pump is capable of flow rates from 48 - 274.7 gph (182 - 1,040 l/h) and pressures up to 174 psi. 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.
