Specification                                                                                              

Electric submersible pump.                                                                            

Maximum submergence: 20 m. Protection class IP 68.                                  

Max temperature of pumped medium at max power input and continuous duty 40 ºC.                                                                                      

Max medium density 1100 kg/m3 . pH of the pumped medium 5-8. Free passage: 48 x 60 mm. Max number of starts 30/hour.                                

Min impeller diameter for duty with low water level or intermittent dry running. Max impeller diameter requires half motor or more submersed for continuous duty. (Pump can operate lying down.)

‍Starting method and motor protection                                                        

XJS 50 AT: Direct on line start (DOL 400-550 V) with built in AquaTronic unit, which automatically adjusts phase order by dual contactors, ensuring correct motor rotation. Soft start is built in with the AquaTronic unit at 230 V, where three thyristors reduces start current to three times the nominal current. Here two relays ensures correct motor rotation. Soft start is available as option at 400 V.  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.                                                                                              

‍XJS 50: 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 stops the pump at high temperature.
