Bianco PTF37 Capacitor
The Bianco PTF37 is a 0.37 kW single-phase cast-iron peripheral turbine pump commonly found in well & domestic pumps setups. Its motor runs on a 8µF 450V motor-run capacitor in a CBB60-style can — here's the exact replacement and how to confirm it.

Manufacturer-documented8µF · 450V
The Bianco PTF37 cast-iron peripheral turbine pump uses a 8µF 450V 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 our pump-spares records. Match the replacement to 8µF (about 7.2–8.8µF) at 450V or higher; the checklist below covers how to confirm it against your own capacitor.
The capacitor that fits
One listing covers every terminal style — open it and choose your terminal (lug, flying lead, or stud) from the dropdown to match how your old capacitor's wires come out. Not sure? Any works electrically; the terminal is just the connection.
How to be sure you get the right one
- µF must match — the PTF37 needs 8µF (about 7.2–8.8µF), 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 450V (or higher) cap is correct here; a 450V part safely replaces a 370V or 440V one. Don't fit below 450V.
- Check the terminal + size — make sure the new cap physically fits the housing and the connections match (or use a spade adapter).
- When in doubt, read your old cap — the printed µF and voltage on the part you're replacing is the final word.
Common questions — Bianco PTF37 capacitor
What capacitor does the Bianco PTF37 use?
A 8µF 450V 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 Bianco PTF37?
Yes — voltage can be equal or higher, never lower. A capacitor rated 450V or above is fine (450V is the usual choice), as long as the µF still matches (8µF).
