Operation SIMDOS diaphragm metering pump 6.5. Shutdown On completion of the pumping operation, flush the entire system and the pump with a neutral fluid, then pump it empty. To ensure satisfactory start-up when the unit is again required, it is important to ensure that the pump is free of any crystallising, adhesive or curing media. Press the STOP button to end the pumping operation. Unplug the pump from the power supply. 6.6.
SIMDOS diaphragm metering pump Operation If it is possible that pressures in excess to the limits can occur it is important to take the necessary measures, e.g. a pressure relief valve or pressure sensor. For further assistance contact your local KNF specialist. Never apply positive pressure to the suction side of the pump. A small positive pressure of less than 0.5 m water column will cause the pump to block flow in the pumping direction.
