The capacitor to suit the Pedrollo PKM60 listed here is a 10 µF, 450 VAC run capacitor: a CBB60 motor-run type with lug (spade) terminals, for this single-phase peripheral pump. Before ordering, read the µF value printed on your old capacitor. If it says 10 µF (or 10 uF / 10 MFD), this is the part; if it shows a different number, that is the value to buy.
Choosing the right capacitor for the Pedrollo PKM60
The number that matters is the capacitance, printed on the side of the old capacitor as µF, uF or MFD. A replacement should match it, normally within ±5%. The voltage rating must be the same as the original or higher; a 450 VAC part is suitable for a motor on a 230 V supply.
Other PKM pumps, such as the PKM65 and PKM90, share the PKM60’s seal, but that does not mean they take a 10 µF capacitor; go by the value on your own old part. The same rating is also sold as a plain 10 µF 450 V CBB60 capacitor, and the Pedrollo PKM capacitor guide covers the wider range.
Signs the PKM60 capacitor is on the way out
- The motor hums but will not turn, or only starts after the shaft has been turned by hand.
- The pump starts slowly, runs hot, or trips the overload after a short time.
- The old capacitor case is swollen, cracked or leaking.
- A capacitance meter reads well below the µF printed on the case.
Swapping the PKM60 capacitor safely
Turn the pump off at the switchboard and unplug it before opening the terminal box. A run capacitor can hold a charge after the power is off, so discharge it before handling, for example by bridging the terminals with a suitable resistor. Take a photo of the wiring, then move each lead from the old lug terminals to the new ones. If you are not confident working on mains wiring, have an electrician do it. If the pump is also leaking at the shaft, the Pedrollo PKM60 service kit adds the mechanical seal.
Before you order
Check the old part before fitting: match the µF printed on your old capacitor.
