Operating Principle In the MPV Flow Meter 1 , it is the passage of fluid over the set of three screws 2 that causes the device to rotate, unlike the three-screw pump, which moves a fluid when it is driven by an applied force, whether it be an electric motor or a PTO of some kind. The special shape of the screws ensures that their rotation corresponds with exact volumes, quantitatively determined by a highly dependable sensor 3 . The resulting signal, square wave 4 , may be acquired directly by the PLC or processed by dedicated SEIM electronics 5 . 4

An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level.
