Product Introduction
The hygienic design version of the Sigma diaphragm metering pumps is optimized in terms of dead space, with the smallest possible clearances and smooth, wetted surfaces for flexible, easy use in hygiene-sensitive applications.The Sigma product range can be flexibly controlled using a high degree of signal diversity. Standard PTFE multi-layer diaphragms Multi-layer diaphragms (at least two diaphragms stacked on top of each other) prevent feed chemicals from escaping in the event of a malfunction.
Functions and advantages
* Process reliability thanks to PTFE multi-layer safety diaphragm with condition monitoring
* Fast CIP, reliable operation and easy handling
* Simple construction, optimised in terms of dead space and small number of parts, reliable operation, no shaft passage into the media chamber
* Precise metering thanks to the option for adjusting the metering volume in 1% steps by means of stroke rate and stroke length
