DDE 6/10-B-PP/E/C-X-31U2U2FG – Grundfos Dosing Pump

  • Digital Dosing Pump
  • 0.006-6 lph, 10 bar
  • Polypropylene/EPDM/Ceramic
  • 110-230/1/50-60
  • 1000:1 turndown

Alldos, Grundfos Alldos dosing pumps – the SMART Digital generation DDA, DDC and DDE with powerful variable-speed stepper motor brings state-of-the-art technology to perfection. Combined expert knowledge and the new patented solutions set future standards. Traditional technologies such as stroke length / stroke frequency adjustment with synchronous motor or solenoid drive become a thing of the past.

Flows 0.0025-30 lph, pressures to 16 bar, 100-240V/1ph/50-60hz, IP65 and available in PVC/PP/PVDF or 316SS all complete with full PTFE diaphragm.

Unique flexibility with only a few variants

The included click-stop mounting plate makes the new pump more flexible. Three different positions are possible without using any additional accessories, such as wall brackets. Service and pump exchange can now be done easily and fast just by clicking the pump in and out of the mounting plate. The control cube on the DDA and DDC pump can be lifted and turned easily into three different positions: front, left or right.

A turn-down ratio of up to 3000:1 (DDA 7.5/16 only), all other 1000:1, a wide supply voltage range (100-240 V; 50/60 Hz), combined connection sets and other features reduce the models and variants to a minimum.

Precise and easy setting / usability and interaction

The operator can easily install the pump and set it to discharge exactly the quantity of dosing liquid required for the application. In the display, the setting of the pump is read out directly, the flow is shown in ml/h, l/h, or gph. The click wheel (turn-and-push knob) and the graphical LC display with plain-text menu in more than 20 languages make commissioning and operation intuitive. As the LCD is backlit in different colours, the pump status can be seen from a distance (traffic-light concept).

Thanks to a variety of operation modes, signal inputs and outputs, the pump can easily be integrated into every process.

Advanced process reliability

An intelligent drive and microprocessor control ensures that dosing is performed precisely and with low pulsation, even if the pump is dosing high-viscosity or degassing liquids. Malfunctions, caused e.g. by air bubbles, are detected quickly by the maintenance-free FlowControl system and then displayed in the alarm menu. The AutoFlowAdapt function automatically adjusts the pump according to the process conditions, e.g. varying backpressure. The integrated flow measurement makes additional monitoring and control equipment redundant.

Designed to save costs

In general, the investment for a dosing pump installation is low compared to its life cycle costs including the cost of the chemicals. The following features make the SMART Digital DDA, DDC and DDE pumps contribute to low life cycle costs:

No under-dosing or overdosing due to high dosing accuracy and FlowControl.

Longer maintenance intervals thanks to the universal chemical resistance of the full-PTFE diaphragm

Reduced energy consumption thanks to state of the art drive technology.
