Grundfos SQ and SQE Pump Accessories

Three genuine Grundfos parts that come up repeatedly on SQ and SQE installations and service calls. Each is ordered by its own Grundfos product number; pick the one you need from the Accessory dropdown.

The cable kit is the 5 ft, 14 AWG NSF-listed motor lead for MS 3 and MSE 3 submersible motors, motor model C. It is the pigtail that leaves the motor and is spliced to the drop cable, and it is the part to order when the factory lead has been damaged during installation or pulled. Drop cable itself is sized separately from the pump gauge tables — a 1/2 HP unit on 115 V needs far heavier wire for the same setting depth than the same pump on 230 V.

The wrench separates the pump end from the motor on SP, SQ and SQE pumps. It is the tool the installation instructions call for when refilling motor liquid, replacing a motor, or fitting a pump end to a motor, and it is not included with a pump.

The pressure transducer is the 0-120 PSI, 1/2 in NPT analog sensor a CU 302 reads to hold a constant pressure. Order it as a replacement, or alongside CU 302 part number 92799799, which ships without a sensor. CU 302 part number 92817764 already includes one.
