Grundfos CU302 SQE Pump Controller w/40-100PSI Sensor

CU302 SQE Pump Controller w/40-100PSI Sensor The Grundfos CU302 is the dedicated controller for the SQE variable-speed submersible pump system, delivering precise, constant-pressure water supply for residential and light commercial well applications. Paired with the included 40–100 PSI pressure sensor, the CU302 continuously monitors system pressure and automatically adjusts pump speed in real time to maintain a steady, consistent pressure setting regardless of demand fluctuations — eliminating the pressure swings and pump cycling common with traditional fixed-speed systems. The result is a noticeably smoother water supply experience, reduced energy consumption, and significantly extended pump life.
