The Grundfos 97722639 is a SMART Digital S DDA 17-7 diaphragm dosing pump rated for 17 l/h (4.5 GPH) at up to 7 bar (102 psi), supplied with an installation kit for a complete chemical-feed hookup.
This configuration uses a PVC dosing head, EPDM gasket, ceramic valve ball, and PTFE diaphragm, in the FCM control variant — flow control and measurement with alarm relay and analog input. It includes the installation kit with 3/8" x 1/2" hose and standard valve, so suction and discharge lines connect out of the box. Universal 100–240 V, 50/60 Hz single-phase supply; setting range up to 1:3000.
The EPDM gasket build suits chemicals that attack FKM (many hypochlorite and caustic services) — verify compatibility against your chemical. Send us your application details and we'll point you to the right part number.
