Grundfos pump capacitors
We've documented the run-capacitor fitment for 3 Grundfos pump models spanning jet pressure pump and pressure booster pump, with values from 20µF to 40µF at 450V.
The run capacitor your Grundfos pump needs, by model. Match the µF and voltage to your own capacitor before ordering — voltage can go up (e.g. 450V for a 370V cap), never down. New to this? Our pump capacitor guide covers run vs start capacitors, how to read the µF off your own part, and the CBB60 / CBB65 / CD60 difference.

|---|---|---|---|
| JP5 jet pressure pump | 20µF · 450V | Manufacturer-documented | Get this capView |
| JP6 jet pressure pump | 25µF · 450V | Manufacturer-documented | Get this capView |
| MQ3-45 pressure booster pump | 40µF · 450V | Customer-reported | Get this capView |
Source tells you how we know: Manufacturer-documented / Confirmed fit are sourced facts; Typical for this class / Customer-reported are best estimates — always confirm the µF on your own capacitor.
