Bianco B25VAS2 Capacitor

The Bianco B25VAS2 is a 0.25 kW single-phase submersible dirty-water vortex pump commonly found in well & domestic pumps setups. Its motor runs on a 9µF 450V motor-run capacitor in a CBB60-style can: here's the exact replacement and how to confirm it.

Pump type: submersible dirty-water vortex pump
Motor: 0.25 kW · single-phase
Run capacitor: 9µF · 450V · CBB60
Application: Well & domestic pumps
Also sold as: B25VAS2-FF
Fitment source: Manufacturer-documented, our pump-spares records

Manufacturer-documented9µF · 450V

The Bianco B25VAS2 submersible dirty-water vortex pump uses a 9µF 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 9µF (about 8.1-9.9µF) at 450V or higher; the checklist below covers how to confirm it against your own capacitor.

Matching capacitor

We don't currently stock this exact value (9µF 450V). 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 B25VAS2 needs 9µF (about 8.1-9.9µF), within ±5% of the label. 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 B25VAS2 capacitor

What capacitor does the Bianco B25VAS2 use?

A 9µF 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 B25VAS2?

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 (9µF).
