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.

Pump type: cast-iron peripheral turbine pump
Motor: 0.37 kW · single-phase
Run capacitor: 8µF · 450V · CBB60
Application: Well & domestic pumps
Also sold as: PTF37M, PTF37CORE
Fitment source: Manufacturer-documented, our pump-spares records

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.

How to be sure you get the right one

µF must match: the PTF37 needs 8µF (about 7.2-8.8µF), 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 PTF37 capacitor

What capacitor does the Bianco PTF37 use?

An 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).
