‍Starting method and motor protection                                                          

‍XJ 80 AT: Direct on line start (DOL 500-550 V) with built in AquaTronic unit, which automatically adjusts phase order by dual contactors, ensuring correct motor rotation.  Soft start (230-400 V) is built in with the AquaTronic unit, where three thyristors reduces start current to three times the nominal current. Here two relays ensures correct motor rotation. The AquaTronic unit monitors motor temperature, by use of NTC thermistors built into stator windings, and stops the motor at high temperature. It will also stop the motor at high amperage or if a phase is missing.                                                                                                      

‍XJ 80: Direct on line start with built in contactor. Pumps to be used with VFD or 1000 V must have terminal block instead of contactor. Thermal switches (140 °C, ±5) built into the stator windings are connected to the contactor and stop the pump at high temperature.                                                                                              

‍Power cable  

20 m type H07RN8-F (standard cable):   4 x 2.5 sq.mm. (400-550 V)                                                              

‍Shaft seal  

Double mechanical seal in oil bath.  Primary seal: Silicon carbide on silicon carbide.  Secondary seal: Silicon carbide on carbon.                                                

‍Bearings  

Upper bearing: Single-row deep groove ball bearing.    Lower bearing: Double angular contact ball bearing.
