The submersible sludge pump XJS 25 is ideal for pumping sludge and water mixed with solids. Pumps with built in AquaTronic unit will always have correct direction of impeller rotation, ensuring peak performance and reduced wear. 50 Hz: head max 18 meters, flow max 16 l/s. 60 Hz: head max 20 meters (66 feet), flow max 16 l/s (254 gpm).
The AquaTronic unit (AT) replaces the built-in contactor in the basic pump configurations and ensures that the motor always rotates correctly, no matter how the phases are connected. Key benefits of the AquaTronic unit include:
Correction of motor rotation if phases are improperly connected
Run mode (no panel needed)
Integrated start equipment (direct or soft start depending on pump model)
Motor protection against high temperature, high amperage and missing phase
Anti-clog function
If the pump is also equipped with an optional level sensor, AquaTronic provides:
Precise level control
Protection against dry running
Energy save mode (energy is saved through stopping at dry run and starting by level sensor)
AquaTronic service diagnostic program
Connecting a PC to the AquaTronic unit via USB cable provides access to the service diagnostic program, which offers:
Pump status data, pump operating history, pump failure history, pump service/maintenance history, digital manual and spare part documentation
AquaPlug (50 Hz only)
AquaPlug is an option that combines with AquaTronic to provide additional alarm and start/stop functions, as well as indications for important parameters.
The world’s smartest dewatering pumps for applications in mines, construction sites and tunnels are equipped with the innovative AquaTronic. AquaTronic ensures correct motor rotation, gives motor protection, allows the pump to start via a level sensor, and gives you all the pump performance information in your PC, plus much more.
XJS25 AT: Direct on line start (DOL 230-550 V 50 Hz / 230-575 60 Hz) 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.
XJS25: Direct on line start with built in contactor. Pumps to be used with VFD or 1,000 V must have terminal block instead of contactor.
Thermal switches (140ºC / 284ºF, ±5) built into the stator windings are connected to the contactor and stops the pump at high temperature.
Plug in without having to worry about overheating. Built-in contactor and thermal sensors protect the motor from overheating. Pumps with a built-in AquaTronic unit will adjust electronically for incorrect phase order, ensuring correct impeller rotation.
Reliable and trouble-free operation
The XJS is perfect for pumping sludge and water mixed with solids as it is equipped with a free-flow vortex impeller and a pump volute. The pump design, the robust construction and the premium materials ensure high wear resistance, and the impeller is available in different sizes to meet your specific requirements.
Serviceability
The modular design of the pump range reduces costs by ensuring maximum pump availability with a smaller spare parts inventory. The condition of a pump with a built-in AquaTronic unit can be rapidly checked without disassembly, using its service software.
Saves energy and the environment
The high-efficiency motor and hydraulics are combined with low-friction bearings to reduce power losses. You achieve low total energy costs and minimize your carbon footprint. Environmentally safe white oil is used in the oil casing for easy inspection of seal conditions.
Neptune is a company specialized in the rental and sale of pumping equipment for clean water, wastewater and water loaded to industry, construction and communities. Its rental fleet includes 90% of dewatering pumps and 10% of sewage pumps. Neptune has already trusted Sulzer as a supplier for many years and has ordered several dewatering and sewage pumps.
Robust Sulzer dewatering equipment endures tough mine environment. Built-in intelligence in submersible drainage and sludge pumps XJ/XJS prevents loss of capacity due to connection errors and provides early warnings that allow service at lower cost.
