Davey Silensor SLS200 Capacitor

The run capacitor to suit the Davey Silensor SLS200 is listed here as a 12 µF (12 uF / 12 MFD), 450 VAC CBB60 motor-run capacitor with lug (spade) terminals. It stays in circuit whenever the single-phase motor is running. Before ordering, read the µF value printed on your old capacitor: if it is not 12 µF, choose the capacitor that matches your old one.

Choosing the right capacitor for the Davey Silensor SLS200

The number that matters is the capacitance, printed on the side of the old capacitor as µF, uF or MFD. A replacement should match that figure within about 5%, and its voltage rating should be the same as the original or higher. This capacitor is 12 µF with a 450 VAC rating, which covers a pump on a normal 230 V household supply. Motors are sometimes rewound or swapped over the years, so trust the old capacitor in your hand over any list, including ours. Our SLS200 capacitor guide has more on the capacitor for this pump.

Signs the SLS200 run capacitor is failing

Run capacitors gradually lose capacitance with heat and age. The usual signs are:

• The motor hums but won’t turn, or only starts if the shaft is flicked by hand.
• The pump trips the breaker or thermal overload soon after starting.
• The motor runs hot and slow.
• The old capacitor case is swollen, split or leaking.

Other Davey pumps listed at 12 µF

We list the same 12 µF 450 VAC rating for the Davey Dynaprime, Davey HS50, Davey HS60, Davey PACR100, Davey PCCR100, Davey PCCR150, Silensor SLS75, Silensor SLS100, Silensor SLS150 and Davey XP Series. It is also sold on its own as a plain 12 µF 450 V CBB60 capacitor. Whatever the pump, check the µF printed on the old capacitor first. Before touching the terminals, switch off and isolate the pump and discharge the old capacitor, because it can hold a charge after the power is off. If the shaft seal is weeping too, the Silensor SLS200 service kit includes this capacitor and the 5/8″ seal, and capacitors for other models are on our Davey service kit index.

Before you order

Check the old part before fitting: match the µF printed on your old capacitor.

What size capacitor does a Davey Silensor SLS200 take?

This listing for the Davey Silensor SLS200 is a 12 µF 450 VAC run capacitor. Always match the µF printed on your old capacitor, and if it shows a different value, order that value instead.

What terminals does the Silensor SLS200 capacitor have?

The capacitor to suit the Davey Silensor SLS200 has lug (spade) terminals on a CBB60 motor-run body.

Can I fit a capacitor with a higher voltage rating to my Silensor SLS200?

Yes, a higher voltage rating is fine as long as the µF matches. Never fit one rated lower than the original on a Silensor SLS200.

How do I know if my Davey Silensor SLS200 capacitor has failed?

If the Silensor SLS200 motor hums but won't start, trips the breaker, or runs hot and slow, the run capacitor is the first thing to check. A swollen or leaking case is a clear sign it needs replacing.

Is there a kit with the seal and capacitor for the SLS200?

Yes. The Davey Silensor SLS200 service kit pairs this 12 µF capacitor with the 5/8″ mechanical seal, for when the pump is already apart.

What if it doesn't fit?

If you're unsure, send us a photo of your old part and the pump's label before ordering.
