XJ 110

Sulzer submersible dranaige pump XJ 110

The submersible drainage pump XJ 110 is ideal for pumping water and dirty water mixed with light abrasives. Pumps with built in AquaTronic unit will always have correct direction of impeller rotation, ensuring peak performance and reduced wear. 50 Hz: head max 52 meters, flow max 54 l/s. 60 Hz: head max 63 meters (207 feet), flow max 55 l/s (873 gpm).

Starting method and motor protection

XJ 110 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 (400 V) is built in with the AquaTronic unit, where three thyristors reduces start current to three times the nominal current. Here two relays ensure 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 110: 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.
