SafeGuard (photo) is an IoT-enabled (internet of things) pump-monitoring system that remotely tracks, records and alerts users to key performance indicators – such as leak detection, stroke rate and total stroke count – of air-operated double-diaphragm (AODD) pumps during operation. It provides realtime alerts via SMS or email to indicate any noteworthy change in operations that may be a precursor to or indicators of component failure. SafeGuard also provides the ability to store maintenance records to help identify patterns to further enhance preventative maintenance plans. SafeGuard has been designed to monitor a single pump or a fleet of AODD pumps within one dedicated software system. The connected SafeGuard system is composed of a single battery-powered sensor mounted directly onto the pump. This sensor collects and analyzes pump-performance data in real time and transmits it to a central gateway for encryption and transmission to the Cloud, where it can be accessed through a secure smartphone app or online portal. – Wilden Pump and Engineering Co., Grand Terrace, Calif.
