Operation Diaphragm Pump UN035_I EX Operation Only operate the pump under the operating parameters and conditions described in chapter 4, Technical data. Make sure the pumps are used properly (see section 2.1). Make sure the pumps are not used improperly (see section 2.2). - Page 17 Make sure that no pressure is present in the lines during switch-on. Switching off the pump KNF recommends: When transferring aggressive media, flush the pump prior to switch-off to increase the service life of the diaphragm (see section 8.2.1).
