New Cloud-Based, Remote Performance Monitoring and Alert System for AODD Pumps

Advances in digital-monitoring technology and the growth and acceptance of IoT principles have opened the door for users of AODD pumps to better inform themselves of the capabilities and potential shortcomings of the technology.


Manufacturing systems are delicate ecosystems that must be kept in tune at all times if they are to operate effectively, efficiently and safely. Key to ensuring the expected level of operation are the pumps used to transfer liquids through the manufacturing process. Therefore, it is imperative that these pumps are able to reliably meet their required demands. This makes monitoring pump performance a critical consideration for facility operators, but staying on top of that is often easier said than done, even when the most tightly considered maintenance plans are developed and put in place.

So, how do manufacturing-facility operators keep from tossing and turning at night at the thought of costly system failures and downtime? The answer can be found in the industry’s first air-operated double-diaphragm (AODD) Internet of Things (IoT) enabled remote performance monitoring and alert system. Called Wilden® SafeGuard™, it allows the AODD pump to be remotely monitored 24/7 via continuous Cloud connectivity. It is a true game-changer in optimizing AODD-pump performance, reliability, and cost of operation and maintenance.

The Wilden SafeGuard system consists of a battery-powered stroke sensor and transmitter (called an Edge device) that is installed on the pump. The sensor collects and analyzes pump performance data in real-time and transmits it to a central gateway for encryption and transmission to the Cloud. Once stored on the Cloud, real-time and historic operational information can be accessed by the user anywhere in the world through a secure smartphone app or an online portal. 

Anticipating potential failure conditions is not the only benefit of remote diagnostic technology. Since pump performance is likely to change over time, whether by normal wear or through outside system influence, monitoring indicators such as stroke rate or stroke count can be an invaluable tool for the operator. Any variance can be noted and recorded, letting the operator know if a failure may be imminent or if a proactive maintenance check may be needed.

The design and operation of the Wilden SafeGuard system allows for complete monitoring and real-time alerts related to a number of critical performance parameters for the pump (diaphragms, balls, seats). These readings can show the user such things as: 

  • Leak detection to indicate diaphragm leaks and failures, preventing product loss and safety hazards 
  • Stroke rates to monitor changes to highlight performance abnormalities 
  • Stroke count for batching and setting maintenance schedules 
  • Real-time alerts via SMS or email to indicate any noteworthy change in operation that may be a precursor to pump or component failure

Pump breakdowns and compromised performance, no matter how comprehensive the maintenance schedule, are always possible, making it imperative that the operators of manufacturing facilities know how their pumps have been performing. Advances in digital-monitoring technology and the growth and acceptance of IoT principles have opened the door for users of AODD pumps to better inform themselves of the capabilities and potential shortcomings of the technology. Recognizing this, Wilden has created Wilden SafeGuard, a digital, Cloud-based pump-monitoring tool that relies on cutting-edge diagnostics that give AODD pump users the ability to observe exactly how – at any moment in time – their pumps are operating and if any performance-related issues may occur in the foreseeable future.
