Submersible sludge pump XJS 50

Always solid results when pumping sludge

The submersible sludge pump XJS 50 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 28 meters, flow max 25 l/s. 60 Hz: head max 31 meters (102 feet), flow max 26 l/s (413 gpm).

 

Main benefits
  • Plug-and-pump installation without having to worry about overheating.
  • Pumps with a built-in AquaTronic unit will adjust incorrect phase order, ensuring correct impeller rotation.
  • A wide range of pumps, up to 11 kW, makes it easy to find a solution for any pumping need.
  • Clog-free pumping with pumps designed for pumping sludge and water mixed with solids.
  • Non-overloading performance with two different impellers for each pump model. The small impeller allows the pump to run in low-level applications.
  • Serviceability with modular design. Pumps with a built-in AquaTronic can be checked without disassembly, using its service software.

AquaTronic built-in electronic supervision

AquaTronic option

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 and AquaTronic control panel

AquaPlug and AquaTronic control panel are options that combine with AquaTronic to provide additional alarm and start/stop functions, as well as indications for important parameters.

Starting method and motor protection

Starting method and motor protection

XJS50 AT: Direct on line start (DOL 400-550 V 50 Hz / 380-575 V 60 Hz) 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 ensure correct motor rotation. Soft start is available as option at 400 V 50 Hz / 380-460 V 60 Hz.
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.

XJS50: 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 / 284º  F, ±5) built into the stator windings are connected to the contactor and stops the pump at high temperature.

Discharge connections

2 1/2”, 3” (standard), 4” hose connections
2 1/2”, 3”, 4” G/B.S.P. threaded connections
2 1/2”, 3”, 4” NPT threaded connections
Benefits

Plug-and-pump installation

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.

Applications

Dewatering in construction

From roads and bridges to ditches and dams, construction sites are difficult places to work. Construction site managers need solid economic reasons for purchasing equipment. Our submersible dewatering pumps provide them.

Dewatering in tunneling

A tunnel construction is a complex worksite were many different variables need to be taken into consideration, flooding is one of them. Our drainage and sludge submersible dewatering pumps are lightweight, portable and start when you plug them in.

Mining

Whether on the surface or underground, the conditions in mines are harsh. Besides the mud, slurry, stones, and rocks, there are large volumes of water to remove in order to keep production moving. Our dewatering pumps are rugged and ready, taking on the toughest drainage and sludge removal.
