Control and Monitoring (AquaTronic)

The AquaTronic unit is an optional built-in electronic control system available for XJ 25-110, XJC 50-110, and XJS 25-110 submersible dewatering pumps.

Key benefits of the AquaTronic unit include:

• Automatic Correction of Motor Rotation: Compensates for incorrect phase order.
• Integrated Start Equipment: Direct or soft start, depending on the pump model.
• Motor Protection: Safeguards against high temperature, high amperage, and missing phases.
• Anti-Clog Function: Attempts to free a blocked impeller with backspin and automatic restart.
• Service Diagnostics Program: Connects to a PC via USB cable to access pump status data (temperature, voltage, moisture), operating history, failure history, service/maintenance history, digital manual, and spare parts documentation.

When equipped with an optional level sensor, AquaTronic provides:

• Precise level control.
• Protection against dry running.
• Automatic start/stop at specified water levels, reducing power consumption and wear.

When combined with an AquaPlug or AquaTronic control panel, additional features become available:

• Alarm and start/stop functions.
• Indications for important parameters.
• Energy save mode for automatic on/off functionality with level sensors.
• Flashing LED light alarms and service indication light.
• Automatic restart when power supply problems (e.g., unbalanced voltage, low/high voltage) are resolved.

Accessories and Options

• AquaTronic Unit: Built-in electronic intelligence for correct motor rotation, motor protection, and service diagnostics.
• AquaPlug and AquaTronic Control Panel: Provides additional alarm, start/stop functions, and parameter indications. AquaPlug is available for 16 A or 32 A sockets.
• Level Sensor: For precise and cost-effective water level control, reducing power consumption.
• SoftDrive: Built-in concept for J 205 pumps, reducing starting current and allowing smaller generators.
• Flotation Ring: Easy-to-install ring for pumps up to 45 kg (J 12-15, XJ 25-40).
• Modular Flotation System: Available for pumps from 59 to 600 kg (XJ 50-110, XJS 50-110, J 205-604).
• Protective Belts: Zinc anode belts for galvanic corrosion protection. Cast parts can also be protectively coated for salty or brackish water.
• Stainless Steel Impellers: Available for J 205HD and J 405HD for enhanced corrosive and abrasive resistance.
• Polyurethane Wear Rings: Option on J 205-604 for increased resistance when pumping fine sand and abrasives.
• Series Connections: Standard drainage pumps can be rebuilt for high head applications.
• Bottom Suction Adapter: For J 12-15, replaces the standard bottom plate for near-total water removal.
• Repair Kits: Available for all submersible dewatering pumps, containing common parts for typical repairs.
