Grundfos Dosing Pumps
DDA 7.5-16, 17-7, 30-4, 120-7, 200-4
​
The SMART Digital DDA is a compact positive displacement, diaphragm dosing pump with variable-speed drive (stepper motor) and intelligent control electronics with minimum energy consumption. The SMART Digital Dosing series operates at full stroke length to ensure optimum accuracy, priming and suction, even for high-viscosity or degassing liquids. The duration of each discharge stroke varies according to the capacity set, resulting in optimum smooth and continuous discharge flow. The click-stop mounting plate allows installation in three different positions without additional accessories. The control cube can easily turn into the front, left, or right position. The click wheel and the multi-colored backlit graphical, plain-text LC display make commissioning and operation intuitive. A transparent cover protects the control elements.

DDI 60-10, 150-4
​
The Grundfos DDI range was created because accurate dosing demands precision. These compact units combine perfect precision with a user interface that lets you set the dosing feed rate you want directly on the pump – without spending time on complicated calculations beforehand. Available materials include PVC, PVDF, polypropylene, and 316 stainless steel.
DME 60-10, 150-4, 375-10, 940-4
Compact positive displacement diaphragm dosing pump, integrated variable speed motor drive, in an IP 65 plastic enclosure. The pump is designed for optimum user-friendliness, accuracy, and reliability
. It has a logical control panel with one-touch buttons and a multi-language backlight display. Each function's capacity to be dosed is set directly in gal,l, or ml per hour.
The pump can be calibrated to the actual installation for enhanced accuracy through a simple calibration function. The turn-down ratio is 1 to 800 with the same accuracy and uniform dosage with reduced pulsation throughout the entire capacity range. The pump is also equipped with a maximum capacity function (100%) that allows it to work for a preset time at max capacity to facilitate priming or ordinary maintenance without modifying the pump's settings.
The liquid end is composed of:
Pump head
PTFE-coated diaphragm
Ball valves
Manual bleed valve
