Sulzer submersible dranaige pump XJ 40

The submersible drainage pump XJ 40 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 34 meters, flow max 23 l/s. 60 Hz: head max 36 meters (118 feet), flow max 22 l/s (349 gpm).

Starting method and motor protection

XJ 40 AT: Direct on line start (DOL 230-550 V) with built in AquaTronic unit, which automatically adjusts phase order by dual contactors, ensuring 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 40: 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
