Davey VM 0.75kW (VM1-15M1 / VM3-8M1 / VM5-5M1) Capacitor

The Davey VM 0.75kW (VM1-15M1 / VM3-8M1 / VM5-5M1) is a 0.75 kW single-phase pressure pump (multistage) commonly found in well & domestic pumps setups. Its motor runs on a 16µF 450V motor-run capacitor in a CBB60-style can: here's the exact replacement and how to confirm it.

Pump type: pressure pump (multistage)
Motor: 0.75 kW · single-phase
Run capacitor: 16µF · 450V · CBB60
Start capacitor: 100µF (separate)
Tolerance: ±5%
Application: Well & domestic pumps
Also sold as: VM1-15M1, VM3-8M1, VM5-5M1, VM1-15, VM3-8, VM5-5, VM 0.75kW
Fitment source: Manufacturer-documented

Manufacturer-documented16µF · 450V

The Davey VM 0.75kW (VM1-15M1 / VM3-8M1 / VM5-5M1) pressure pump (multistage) uses a 16µF 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 manufacturer / supplier documentation. Match the replacement to 16µF (about 14.4-17.6µF) at 450V or higher; the checklist below covers how to confirm it against your own capacitor.

This pump also uses a separate 100µF start capacitor. We stock CD60 start capacitors (50-500µF, 250V), but its voltage isn't in our records, so we haven't matched it to a CD60. Read the µF and voltage on your old start capacitor and ask us to check the match. It is a different part from the run capacitor above; replace whichever one has failed.

How to be sure you get the right one

µF must match: the VM 0.75kW (VM1-15M1 / VM3-8M1 / VM5-5M1) needs 16µF (about 14.4-17.6µF), 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 - Davey VM 0.75kW (VM1-15M1 / VM3-8M1 / VM5-5M1) capacitor

What capacitor does the Davey VM 0.75kW (VM1-15M1 / VM3-8M1 / VM5-5M1) use?

A 16µF 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 Davey VM 0.75kW (VM1-15M1 / VM3-8M1 / VM5-5M1)?

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 (16µF).

Does the VM 0.75kW (VM1-15M1 / VM3-8M1 / VM5-5M1) need a start capacitor as well?

Yes, alongside the 16µF run capacitor it uses a separate 100µF start capacitor. Replace whichever has failed (or both if you're unsure).
