DIAPHRAGM RUPTURE DETECTION SYSTEM mRoy A with diaphragm rupture detection system including pressure switch. GENERAL INFORMATION Milton Roy's diaphragm liquid ends arc, by design, leakproof and durable. In some applications, however, added assurance is desired to protect the pump from hostile chemicals, or protect the process from contamination by hydraulic fluids. For these situations, Milton Roy has developed a highly reliable diaphragm rupture detection This system is available for metallic liquid end mRoys, maxRoys, and Centrac or Milroyal pumps with HPD liquid ends. An alternate design utilizing conductivity sensing in an intermediate chamber be- tween two diaphragms is also available for a number of liquid ends. The system consists of two separate diaphragms, a hollow intermediate ring, and a pressure switch and/or gauge. During normal operation, the two diaphragms are pushed tightly together and are separated only around their outside edge by the intermediate ring. Because there is no fluid and very little air between the two dia- phragms, the system does not experience pressure from the process when both dia- phragms are intact. The rupture detection system senses process pressure only when one of the diaphragms rupture. Once a rupture occurs, a pressure gauge provides visual indication, or an optional pressure switch provides contact closure for remote indication.
