Key Features & Benefits
Powerful Servomotor Technology
The SMART Digital XL utilizes advanced servomotor drive technology, replacing outdated stroke length/frequency adjustment mechanisms and frequency converters with asynchronous motor drives. This modern approach delivers superior precision and reliability for large-volume dosing applications.
Exceptional Dosing Accuracy
With dosing accuracy of ±1.5% of the actual setpoint, the SMART Digital XL ensures precise chemical delivery even at minimum flow rates. The impressive 1:800 turn-down ratio enables accurate dosing across the entire performance range without pump head changes.
Integrated FlowControl System
The proprietary FlowControl system (DDA-FCM) features an integrated positive-displacement flowmeter that measures the exact dosed volume per stroke. The intelligent controller automatically corrects dosing flow, eliminating the influence of:
- Temperature variations
- Counterpressure changes
- Viscosity fluctuations
- Air bubbles in the suction line
AutoFlowAdapt Function
Available on DDA FCM models, AutoFlowAdapt provides automatic failure correction with full control of the dosing process on both suction and pressure sides. The system detects air bubbles and automatically initiates the priming program when needed.
High-Viscosity Capability
SMART Digital XL handles degassing chemicals such as hypochlorite and high-viscosity liquids up to 3,000 mPas, expanding application possibilities beyond standard dosing pump capabilities.
Concentrated Chemical Dosing
The precision and control of SMART Digital XL allows dosing of concentrated chemicals without dilution, delivering significant operational benefits:
- Reduced chemical consumption
- Lower transportation costs
- Smaller dosing tank requirements
- Minimized storage space
Process Safety & Reliability
Automatic Failure Correction
The intelligent control system provides safe dosing with automatic failure correction, delivering:
- Reduced operator intervention time
- Increased system safety
- High process reliability
- Low failure rate
Pulsation-Free Dosing
Dosing is performed almost pulsation-free without requiring additional accessories. This eliminates overdosing and improves both environmental protection and workplace health safety.
Double-Diaphragm Leakage Detection
Available as an optional feature on all models, double-diaphragm leakage detection provides an additional safety layer for critical applications handling hazardous or expensive chemicals.
Pressure Monitoring
DDA FCM models include minimum and maximum pressure monitoring, providing immediate alerts for system anomalies and protecting downstream processes.
Simplified Selection & Inventory
Three Sizes Cover All Needs
With just three pump sizes (60-10, 120-7, 200-4), the SMART Digital XL range covers dosing requirements from 0.075 l/h to 200 l/h, simplifying pump selection and reducing spare parts inventory.
Universal Voltage Compatibility
The wide power supply range (100-240 V, 50/60 Hz) enables global deployment without electrical modifications, further reducing variant complexity.
Two Model Variants
With only DDE (Eco) and DDA (Advanced) models, system designers can easily specify the right pump for any dosing application based on control and monitoring requirements.
Installation Cost Reduction
Integrated Flowmeter
The built-in positive-displacement flowmeter eliminates the need for external flow measurement devices, reducing:
- Equipment costs
- Installation complexity
- Potential failure points
- Calibration requirements
