Grundfos DDE 6-10 B -Dosing Pump

Grundfos DDE 6-10 B Dosing Pump: Full Description

This is a dosing pump from the Grundfos SMART Digital Dosing series, designed for the precise and reliable dosing of chemical reagents in various fields. The pump features advanced digital dosing technology, ensuring high accuracy, efficiency, and ease of use.

Key Features and Purpose

• Purpose: Dosing of liquid reagents in water treatment processes, wastewater treatment, as well as in the food, chemical, and other industries. It is ideally suited for tasks that require a precise supply of chemicals.
• Pump Type: A compact positive displacement diaphragm pump with adjustable speed (stepper motor). This technology ensures smooth and consistent dosing without peak loads.
• Performance:
  • Maximum flow rate: 6 l/h (1.59 GPH).
  • Minimum flow rate: 6.0 ml/h.
  • Turn-down ratio: 1:1000, which guarantees exceptional accuracy even at very low flow rates.
• Maximum Pressure: 10 bar (145 psi).
• Accuracy: Dosing repeatability is less than 5%, which is a high standard for this class of equipment.

Application in Reverse Osmosis Systems

The Grundfos DDE 6-10 B dosing pump is often used in reverse osmosis systems for the precise and continuous dosing of antiscalants. Antiscalants are chemical reagents that prevent the formation of scale (mineral deposits) on the surface of membranes.

Thanks to its high accuracy (a turn-down ratio of 1:1000) and reliability, the Grundfos DDE 6-10 B pump ensures that the exact required amount of antiscalant is delivered. This helps to:

• Protect Membranes: Prevent fouling and premature failure.
• Increase Efficiency: Maintain stable reverse osmosis system performance.
• Save on Reagents: Avoid over-dosing, which reduces operational costs.

What's Included in the Box

• The Grundfos DDE 6-10 B dosing pump itself.
• Two pump connectors (for hoses).
• An injection valve.
• A foot valve (suction valve).
• A set of hoses: discharge ( 2 meters), suction (2 meters), and de-gassing (2 meters).
• A mounting kit with a quick-release plate.

Advantages and Technical Data

• Digital Dosing Technology: The pump operates with a full diaphragm stroke, ensuring optimal accuracy and reliable suction.
• Simple Control: The flow rate can be easily adjusted with a rotary knob from 0.1% to 100%.
• Reliability and Durability: The pump head is made of Full-PTFE and features double ball valves.
• Ease of Installation and Operation: It comes with a quick-release mounting plate and a built-in de-gassing valve.
• Energy Efficiency: The intelligent electronic control system and variable-speed motor consume minimal power.
