Diaphragm rupture is most commonly by large abrasives mixed in the fluid, which can cause a diaphragm to tear. The All-Safe DRM offers safe fluid handling and is therefore suitable for use in chemical processing applications.
The system provides two layers of protection: first, an early warning sensor installed between the PTFE overlay and the backup diaphragm detects a leak if the PTFE overlay becomes compromised. The sensor can alert operators of the leak before the backup diaphragm is compromised and hazardous fluid enters the air section. A second critical leak detection sensor is installed in the air section itself. Should both diaphragms become compromised, this sensor will detect fluid in the air section.
Both the early warning and critical sensors can be configured to take a variety of actions should a leak be detected, such as turning on a warning light, sounding an audible alarm or triggering pump shut-off. The All-Safe DRM is powered by 120VAC and the signal cord is available in 5, 10, 15 or 20 ft lengths.
“Not only can this technology prevent major damage to the pump, it can also prevent possible health hazards by alerting pump operators before harmful chemicals are released into the air system in the event of a diaphragm rupture,” said Paul McGarry, All-Flo sales and marketing manager for North America.
The sensor panel can be wall mounted and is housed in a NEMA-rated polycarbonate enclosure, manufactured by All-Flo’s sister company, Integra Enclosures.
