There is a wide range of Grundfos Alldos digital dosing pumps available for various applications.
Grundfos Alldos Digital Diaphragm Dosing Pumps, up to 940 l/h
DME: These high precision Alldos dosing pumps ensures smooth and constant dosing every time. The pump is simple to set up and is equipped with a user friendly display. The new DME pump range can cover a dosing range from 0.075 l/h to 940 l/h. The DME 10-150 has a capacity of 0.075 l/h to 150 l/h and the DME 375 to 940 has a capacity of 0.47 l/h to 940 l/h. Features include: 1. turn down ration of 1:800, 2. integrated over pressure valve, 3. Continuous dosing throughout the whole range 4. Profibus option.
DDI: The DDI is a universal, high performance pump with brushless direct current motor for industrial processes, wastewater treatment (flocculation tools). Features include: 1. Turn-down ration of 1:800, 2. 0/4-20 mA analog output proportional to dosing quality, 3. full-PTFE diaphragm for universal chemical resistance, 4. Comprehensive monitoring system (Flow Monitor, AutoCal).
Grundfos Alldos SMART Digital Dosing Pumps
The Digital SMART range features a variable speed stepper-motor which alters the volume to be dosed by adjusting the discharge speed, while continuously using 100% of the stroke length. This leads to optimum dosing accuracy and better handling of degassing liquids. The SMART models offer the following features:
- Turn-down ration of 1:3000 for DDA 7.5-16 and 1:1000 for all other models.
- Smooth continuous dosing
- Full stroke length
- Improved dosing head/valve design
- Click-stop mounting plate for flexible instillation
- Full-PTFE diaphragm ensuring high realibility
- Wide range power supply 100-240 V, 50/60Hz
SMART Digital DDA: Suitable for high-end applications, the SMART Digital DDA has been designed for complex and demanding applications. In the case for degassing liquids, the DDA can provide flow rates down to 2.5 ml/h. In addition to an extended capacity range and a turn-down ratio of up to 1:3000, it boasts 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 new functions such as auto deaeration.
SMART Digital DDC: Suitable for common applications. With an easy-to-use LCD interface and click wheel, this pump offers impressive features and is simple in functionality. What’s more, 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 highlights including the SlowMode (anti-cavitation) function for highly viscous media and the straightforward calibration mode.
SMART Digital DDE: Offers economical digital dosing for easier applications and is the most cost-effective entry level model with the benefits of Digital Dosing, including; max. turn-down ration of 1:1000 and smooth, continuous dosing. Dosing rates range from 0.006 to 6 l/h. The 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 are ideal for basic OEM applications.
