Davey SJ35-04 Capacitor
The Davey SJ35-04 is a 0.37 kW single-phase pressure pump (jet) commonly found in well & domestic pumps setups. Its motor runs on a 13µF 500V motor-run capacitor in a CBB60-style can — here's the exact replacement and how to confirm it.

The Davey SJ35-04 pressure pump (jet) uses a 13µF 500V motor-run capacitor (CBB60-style) — it's the part that helps the single-phase motor start and keep running smoothly. We source this value from manufacturer / supplier documentation. Match the replacement to 13µF (about 11.7–14.3µF) at 500V or higher; the checklist below covers how to confirm it against your own capacitor.
Matching capacitor
We don't currently stock this exact value (13µF 500V). Browse the closest matches or ask us — we can usually source it.
How to be sure you get the right one
- µF must match — the SJ35-04 needs 13µF (about 11.7–14.3µF), within roughly ±5–10%. Too low and the motor won't start; too high and it runs hot.
- Voltage can go up, never down — a 500V (or higher) cap is correct here; a 450V part safely replaces a 370V or 440V one. Don't fit below 500V.
- Check the terminal + size — make sure the new cap physically fits the housing and the connections match (the SJ35-04 typically uses a flying-lead terminal).
- When in doubt, read your old cap — the printed µF and voltage on the part you're replacing is the final word.
Common questions — Davey SJ35-04 capacitor
What capacitor does the Davey SJ35-04 use?
A 13µF 500V motor-run capacitor (CBB60-style). Always confirm against the rating printed on your existing capacitor before ordering.
Can I fit a higher-voltage capacitor in the Davey SJ35-04?
Yes — voltage can be equal or higher, never lower. A capacitor rated 500V or above is fine (450V is the usual choice), as long as the µF still matches (13µF).
