The gamma/ X solenoid diaphragm metering pump from ProMinent Fluid Controls is user-friendly and has a long service life. A solenoid control measures the back pressure and protects the system from overload. This technology makes a pressure sensor superfluous, meaning that operating safety can be significantly increased since no additional parts come into contact with the feed chemical. It is suitable for continuous micrometering from 1 mL/h thanks to the regulated solenoid drive. It has integrated pressure measurement for greater safety during commissioning and during the process. It includes an integrated seven-day timer for timed metering tasks. It can be integrated into automated processes and used in all industries, and can work as a control unit with the process timer. 412/787-2484; www.prominent.us.
