The solenoid diaphragm metering pump Beta b is now available with an 0/4 to 20 mA input. A magnet moves the solenoid shaft forward and backward by switching on and off. This stroke movement is transferred to the diaphragm in the dosing head. Two non-return valves prevent the feed chemical from flowing back during pumping; and the stroke length and stroke rate can be adjusted to alter the capacity of a ProMinent solenoid driven metering pump. Added to this are a virtually zero-wear drive and excellent continuous running characteristics; easily operated with voltages of 100 to 230 V.
