Tele Process Pump Controller, 250 V ac, +55°C

Pump control, Alternating/parallelAlternated access of two pumps or other devices Even distribution of duty Parallel duty at high demand Operation using 1 or 2 input signals (two modes of operation) Timing offset of the two loads to avoid water hammer effcects Supply voltage selectable via TR2 power modules 2 separate change over relays for device control Width 22.5mm Industrial design Task Two pumps are installed at a sewage pumping station that are to be run alternately for equal periods to ensure equal wear. Solution The pump switchover system activates the pumps alternately, if needed, the second pump can also be activated so that both run at the same time (parallel operation) Use/value Equal wear, and therefore longer service intervals for both pumps Minimised pump failures through nearly equal number of operating hours Peak load coverage Zero-voltage safety in the event of power failures Applications Centrifugal Pumps Sewage Pumps Water & Waste
