Grundfos General-purpose High-performance Dosing Pumps

Digital dosing pumps

Controlled Dosing pumps for chemicals in water treatment, process and chemical engineering, disinfection, pH adjustment, precipitation, polymer addition, biocides, friction reduction, descaling, odor control, coagulants and neutralizing agents. Grundfos metering pumps and systems are easy to install, plumb and operate. We build skid mounted injection units for manual and external control using analog 4‐20mA, digital pulse, and fieldbus input.

DME: digital diaphragm dosing pumps up to 940 l/h

Dosing is precision work, and Digital Dosing™ represents stateof-the-art technology. Grundfos DME Digital Dosing™ pumps combine perfect precision with user-friendliness, covering large dosing quantities up to 940 l/h with few variants.

DME: precise and easy setting

  • Two pump variants: 375 l/h at 10 bar, or 940 l/h at 4 bar
  • Turn-down ratio 1:800 with constant 100% stroke length
  • Adjustable slow mode for dosing high viscosity liquids (up to 3000 mPas)

DDA: high-end solution for complex and demanding applications

  • AutoFlowAdapt: automatically adapts measured flow to attain target flow
  • Auto-deaeration during pump standby
  • Flexible Fieldbus control
  • Turn-down ratio 1:3000 with constant 100% stroke length

DDC: optimal price-performance ratio

  • Two SlowMode steps (25% and 50%),calibration mode, service display
  • External stop, dual-level tank control, 2 relay outputs

DDE: a cost-effective Digital Dosing™ solution

  • Control options: manual control 0.1-100 %, pulse in % of stroke volume, and analogue control (DDE XL)
