Pumps + Get Alerts

All-Flo Pump Co. recently released the All-Safe DRM (Diaphragm Rupture Management) product, which alerts pump operators in the event of a diaphragm rupture. All-Flo is a leading manufacturer of air-operated diaphragm (AOD) pumps.

Ideal for use in chemical processing applications, the All-Safe DRM allows for safe fluid handling by detecting any diaphragm failure in a diaphragm pump. The system provides two layers of protection; an early warning sensor, installed between the PTFE overlay and the backup diaphragm, detects a leak if the PTFE overlay becomes compromised. The sensor alerts pump 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. Should both diaphragms become compromised, this sensor will detect fluid in the air section. 

The early warning and critical sensors can be configured to take a variety of actions when a leak is detected, such as turning on a warning light, sounding an audible alarm or triggering pump shut-off. The All-Safe DRM is powered by 120 VAC, and the signal cord is available in 5-, 10-, 15- or 20-foot lengths. 

“This high-tech product is an exciting rollout for All-Flo and our customers,” said Paul McGarry, All-Flo Sales and Marketing manager for North America. “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.” 

Diaphragm rupture, while rare, can be caused by a number of things – but most commonly by large abrasives mixed in the fluid, which can cause a diaphragm to tear. If a rupture occurs and liquid escapes into the air section, the All-Safe DRM electronic connectivity probes complete a circuit and alert the external sensor panel. The sensor panel can be easily wall-mounted and is housed in a NEMA-rated polycarbonate enclosure, manufactured by All-Flo’s sister company, Integra Enclosures.
