Smart Digital s general cataloque

Summary

Product Identification

The Grundfos SMART Digital range consists of accurate digital diaphragm dosing pumps, utilizing Digital Dosing™ technology pioneered in 1999. These pumps feature powerful variable-speed stepper motors with internal stroke speed control for smooth, continuous dosing.

The range includes two primary lines:

• SMART Digital S: Designed for extreme accuracy at low dosing volumes, up to 30 l/h. Models include DDA, DDC, and DDE.
• SMART Digital XL: Designed for higher flow performance, up to 200 l/h. Models include DDA and DDE.

Applications

SMART Digital pumps are suitable for a wide range of industries and applications, including:

Industries:

• Water treatment
• Industry
• Water utility (drinking water and wastewater)
• Agriculture
• Pool water
• Ultrafiltration

Applications:

• Disinfection
• pH adjustment
• Chemical dosing (e.g., anti foamers, cleaners, biocides, bleaches, surface handling agents)
• Cleaning in place (CIP)
• Coagulation
• Precipitation/flocculation
• Filtration
• Reverse osmosis

General Features

• Accuracy: Market-leading dosing accuracy, with some models deviating less than one percent from the set point at flow rates from 50 ml/h and up.
• Flexibility: High turn-down ratio, wide supply voltage range, mounting plate, and adjustable control cube. Pumps can be reconfigured for new tasks.
• Safety & Reliability: Minimizes spillage, offers auto-deaeration, monitoring, and self-diagnosis features.
• User-friendly: Intuitive wheel and button interfaces, backlit navigation menus in over 20 languages. Calibration is often not necessary.
• Cost-effective: Robust components like the full-PTFE diaphragm provide long operating hours. Advanced control variants can eliminate the need for external flow meters and pulsation dampeners. Energy efficiency saves chemicals and power.
• Liquid Handling: Auto-deaeration feature for degassing chemicals (prevents vapor lock). SlowMode feature for high-viscosity liquids (prevents clogging). Some models can dose liquids with a viscosity up to 3,000 mPas.

• Flow measurement
• AutoFlowAdapt
• SlowMode (anti-cavitation)
• Calibration mode
• Scaling of analogue input
• Service information display
• Relay settings (alarm, warning, stroke signal, pump dosing)
• Inputs for external stop, pulse control, analogue 0/4-20 mA control, low-level signal, empty tank signal
• Output relays (2 relays)
• Analogue output (0/4-20 mA)
• GeniBus input/output
• E-box module (SMART Digital S DDA) or Grundfos CIU (SMART Digital XL DDA) for Profibus DP integration or additional alarm relays.
• Double-diaphragm leakage detection (optional for SMART Digital XL DDA).

See the official PDF for exact tabulated values and feature availability per model and control variant.

Accessories and Service

A complete range of accessories is available to ease installation and operation:

• Installation kit (foot valve, injection unit, hose)
• Multi-function valve (PVDF)
• Rigid suction lance (PE, PVDF) with low level and empty tank signal
• Foot valve for flexible suction line (PE, PVDF, stainless steel)
• Injection unit (PP, PVC, PVDF, stainless steel)
• Hose (PVC, PE, ETFE) in different sizes
• Signal cables for all inputs and outputs
• Dosing tanks in different sizes

SMART Digital pumps have long maintenance intervals, with wear parts in contact with the media typically requiring replacement after 8,000 operating hours or two years. Service kits are available for high-quality pump service and maintenance with original spare parts, including:

• Complete dosing head kit
• Valve and diaphragm kit
• Valve kit
• Diaphragm kit

These kits are available for PP, PVC, PVDF, and stainless steel materials.
