Grundfos 97722438 DDA Dosing Pump

The Grundfos 97722438 is a SMART Digital S DDA 7.5-16 diaphragm dosing pump, rated for 7.5 l/h (2.0 GPH) at up to 16 bar (232 psi). It is a digital metering pump for precise chemical feed in water and wastewater treatment, configured here for fluoride dosing.

This build carries type key DDA 7.5-16 FCM-PVC/V/C-F-31I003BG: a PVC dosing head, FKM (Viton-type) gaskets, ceramic valve balls, and a PTFE diaphragm. The FCM control variant adds integrated flow measurement and flow control, an alarm relay, and an analog input, while the stepper-motor drive delivers a wide setting range up to 1:3000 so a single pump covers a broad dosing window without swapping liquid ends. The pump ships with the installation set: two pump connections, a foot valve, an injection unit, 6 m of PE discharge tube, 2 m of PVC suction tube, and 2 m of PVC vent tube (4/6 mm).

This is the right choice for municipal and industrial fluoride or chemical feed where verified dosing accuracy and repeatability matter. Send us your application details and we'll point you to the right part number.
