The Sigma X diaphragm metering pump covers a capacity range of 21 to 1,040 l/h in versions S1Cb, S2Cb and S3Cb. Its patented multi-layer safety diaphragm guarantees maximum process reliability. Efficient protection of the power end from overloading by means of an integral frequency converter with microprocessor control(ler).
One highlight is the standardised operating concept with click wheel and 4 additional operating keys on a removable operating unit. A large illuminated LCD and a 3-LED display for operating, warning and error messages, visable from all sides, offers additional operating convenience.
The SIgma, like all smart ProMinent metering pumps, can be flexibly connected to various bus systems. It has a large adjustment range thanks to a combination of frequency and stroke length adjustment. The pump works with high precision across the entire frequency range.
Operating statuses are simply remotely transmitted via an additional output or relay module. A built -in timer, included as standard, controls time-dependant metering cycles.
Your Benefits:
Safe: In the event of an accident, the feed chemical does not escape to the outside nor into the pump’s power end.
Integrated relief valve protects the pump against overloading
External control is scalable via potential-free contacts with pulse step-up and step-down, batch mode or via a 0/4-20mA standard signal
