Ecodos Hygienic Diaphragm Pumps feature hermetically tight, sealless construction with smooth internals and a low pump head volume to assure that wetted parts and product contact areas meet 3A sanitary standards. Providing ±1 percent or better metering accuracy, these pumps utilize a four-layer mechanically-actuated diaphragm with pressure switches to automatically detect a perforation, signal an alarm, and shut down the motor.
