The Grundfos 93065137 is a SMART Digital S DDA 7.5-16 diaphragm metering pump, a stepper-motor dosing pump rated to 7.5 l/h (2 GPH) at up to 16 bar (232 psi). It is designed for accurate low-flow chemical dosing in water treatment and process applications.
This build uses a polypropylene (PP) dosing head with an EPDM gasket, ceramic valve balls, and a PTFE diaphragm — the same wetted family preferred for fluoride and similar chemistries where polypropylene compatibility is wanted. The variable-speed stepper motor provides a turndown ratio up to 1:3000 for smooth, continuous dosing across a wide flow range.
It is a good fit where PP and EPDM match your chemical and you need precise low-flow metering. If you want to confirm wetted-material compatibility or the exact connection set for your install, send us your application details and we will point you to the right part number.
KAD is Texas-based and ships from the US, with US support before you buy — short lead times and simple online ordering.
