The Grundfos 10S10-15 CUE 100 package (93335193) brings together the main pumping and control components for a constant-pressure well water system. It pairs a 15-stage stainless steel SP pump end from the 10 GPM family with a 1 HP, 4-inch three-phase submersible motor and the CUE 100 10 variable-frequency drive.
The drive adjusts pump speed using pressure feedback to help maintain the selected water pressure as demand changes. The catalog lists this package for 230 V single-phase supply to the drive, with three-phase output to the motor. Consider this flow family for domestic well water supply where the selected pump curve matches the household demand and total dynamic head.

Read the depth to your pumping water level across the top and the pressure you want down the left; the figure is gallons per minute at that duty point. A hyphen means the pump will not hold that pressure at that depth. Shut-off PSI is the pressure at zero flow — a ceiling, not a working point. Ratings are for the pump at full speed; a CUE 100 holds constant pressure by running slower whenever demand allows. Figures are the Grundfos easy-selection chart and are approximate — verify against the pump curve before specifying.

The CUE 100 is set up at the drive keypad, or over Bluetooth with the free UnyConnect app on an iOS or Android phone. UnyConnect reads status and live operating data, sets the pressure setpoint and control parameters, and shows diagnostic alarms. Remote monitoring away from the wellhead requires the appropriate integration.
UnyConnect is a free app for the CUE 100 drive. Bluetooth must be enabled on the CUE 100 before pairing.
