The Grundfos 97722689 is a SMART Digital S DDA 30-4 diaphragm dosing pump rated for 30 l/h (7.9 GPH) at up to 4 bar (58 psi) — the higher-flow, lower-pressure end of the DDA S range.
This build uses a PVDF dosing head for wide chemical resistance, FKM gasket, ceramic valve ball, and PTFE diaphragm, in the AR control variant (alarm relay plus analog input). It ships with the installation kit including 3/8" x 1/2" hose and standard valve. Universal 100–240 V, 50/60 Hz single-phase supply; setting range up to 1:3000.
Right for higher-volume chemical feed — coagulants, antiscalants, and similar — where discharge pressure stays modest and the controller drives the pump over analog input. Send us your application details and we'll point you to the right part number.
KAD Pumps & Parts is Texas-based and ships from the US — fast dispatch and US support before you buy.
