Genuine Grundfos Parts
SQ and SQE 3-Inch Pumps
14 AWG NSF Lead Kit
0-120 PSI Transducer
Overview
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.
What Ships and What It Needs to Run
Included: the one part you select.
You do not need these for a new pump. Every SQ and SQE ships with its 5 ft motor cable and plug; order the cable kit only to replace a damaged one. The pressure transducer is for a CU 302 bought without its sensor, or as a replacement.
Fits: Grundfos SQ and SQE 3 in pumps (the wrench also fits SP pumps); the status box and potentiometer are SQE-only.
Genuine Grundfos equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
Warranty
24 months from date of installation, but not more than 30 months from date of manufacture. In Grundfos's words, products are “warranted to the original user only to be free of defects in material and workmanship”; the full terms are in the installation and operating instructions on the Data Sheet tab.

Applications
- Repairing a motor lead damaged during installation or pulled in the well
- Splitting a pump end from a motor to refill motor liquid or replace either half
- Building a CU 302 constant-pressure system around a sensorless controller
- Replacing a failed pressure transducer on an existing SQE constant-pressure installation
Before You OrderThe cable kit is specific to motor model C — check the motor nameplate before ordering, because the lead is not interchangeable across motor models. The transducer is a CU 302 part and does nothing on an SQ or on an SQE without a controller. None of these parts is a drop cable: size drop cable from the gauge table on the pump listing, and remember that a 115 V motor draws roughly twice the current of the same pump at 230 V.
