Sulzer submersible dranaige center-line pump XJC 110

The slim design of the submersible drainage center-line pump XJC 110 makes it perfect for applications with limited installation space. The pump 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

XJC 110 AT: Soft start (400 V) is built in with the AquaTronic unit, where three thyristors reduces start current to three times the nomi-nal 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.

XJC 110: Direct on line start with built in contactor. Pumps to be used with VFD or 1000 V must have terminal block instead of con-tactor. Thermal switches (140 °C, ±5) built into the stator windings are connected to the contactor and stop the pump at high tempera-ture.
