Level sensor, AquaPlug and service diagnostics program are monitoring options for pumps with built-in AquaTronic

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 (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. 

 

AquaTronic in XJ pumps

  • AquaTronic - the intelligent option
    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.

Starting method and motor protection

XJ40 AT: Direct on line start (DOL 230-550 V 50 Hz / 230-575 V 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.

XJ40: 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.

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

A double outer casing and good heat convection allow continuous operation at low water levels – or dry running – without motor damage. The pump design, robust construction and premium materials ensure high wear resistance.

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.
