Accurate dosing of chemicals is a crucial part of production processes in many different businesses. From drinking water and wastewater treatment to industrial processing in the pharmaceutical, chemical, and food & beverage industries, dosing exactly the right amount of chemicals is important in order to reach process targets, and in order to lower operation costs while ensuring process safety and reliability.
Intelligent dosing pumps with high technology drive and adjustment mechanisms represent the ideal solution for increasingly complex dosing. They make life easier for users by keeping processes running precisely, reliably and cost-effectively.
Tried and tested Digital Dosing™ solution
Grundfos SMART Digital dosing pump range, available since 2010, is recognized for its state of the art monitoring features that ensure dependable, safe, and economical dosing operations, and for its industry-leading accuracy.
The expanded range is now available in two size categories:
SMART Digital S
• Max flow 8 gph (30 l/h); max pressure 232 psi (16 bar), max turn down
ratio 3000:1
SMART Digital XL
o Max flow 52.8 gph (200 l/h); max pressure 145 psi (10 bar), max turn
down ratio 800:1
The SMART Digital S DDA, DDC, and DDE and the SMART Digital XL DDA and DDE are all based on tried and tested Digital Dosing™ technology from Grundfos. They offer powerful, variable-speed motors, a universal power supply, and a full-PTFE diaphragm that meets the most demanding requirements for chemical resistance and durability. The pumps open up a broad range of dosing applications.
DDA: high-end solution for complex and demanding applications
The DDA is the pump for complex and demanding applications where the focus is on maximum process reliability. It offers FlowControl, pressure monitoring, AutoFlowAdapt, and integrated flow measurement. The package for industrial applications is rounded off by additional operating modes such as a week dosing timer and auto-deaeration.
DDC: optimal price-performance ratio
The DDC offers simple, intuitive click-wheel operation and a graphic LC display in more than 28 languages. All standard modes of operation and inputs/outputs such as analog control or output relay can be integrated into control systems. This pump is suitable for universal use thanks to features such as the SlowMode (anti-cavitation) function for highly viscous media and the straightforward calibration mode.
DDE: a cost-effective Digital Dosing™ solution
The DDE is a cost-effective entry-level model with all the benefits of Digital Dosing™ such as a maximum turn-down ratio of 1000:1 (max flow 4 gph or 15 l/h) and 800:1 (max flow 52.8 gph or 200 l/h) and smooth, continuous dosing.
The dosing rate is set using a logarithmic scale that runs from 0.1-100%. The model’s straightforward pulse control, external stop function, and empty level signal make it ideal for basic OEM applications. The SMART Digital XL DDE additionally offers an adjustable analog input.
