Double Diaphragm With Diaphragm Rupture Detection System

Milton Roy's diaphragm liquid ends are, 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 contami- nation by hydraulic fluids. For these situations, Milton Roy has developed a highly reliable diaphragm rupture detection system.The system consists of two sepa-rate diaphragms, a hollow interme- diate ring, and a pressure gauge manufacturer or switch. During the normal opera- tion, the two diaphragms are pushed tightly together and are separated only around their outside edge by the intermediate ring. The rupture detection system senses a pressure only when a diaphragm ruptures. The system is not affected by changes in pump discharge pressures.This system is available for metal-lic liquid end mRoys, maxRoys, and HPD's. A different design centered around sensing changes in conductiv- ity is also available for a number of liquid ends.
