The capacitor listed to suit the DAB Aquajet 112M is a 25 µF (25 uF / 25 MFD), 450 VAC run capacitor in a CBB60 motor-run body with core leads, for the pump’s 1.0 kW single-phase motor. A pump may have had its motor replaced, so read the µF printed on your old capacitor first: if it shows anything other than 25 µF, that printed value is the one to buy.
Choosing the right capacitor for the DAB Aquajet 112M
Capacitance is the number that matters. A run capacitor has to match the old one’s µF (sometimes written uF or MFD) within about 5 percent, so a 25 µF motor needs a 25 µF capacitor, not 20 or 30. The voltage rating can be the same or higher than the original, never lower; at 450 VAC this one has plenty of margin on a 230 V supply.
Pumps sold as the Aquajet 112M or Aquajet 112 may carry a different capacitor if the motor has been changed, so match the µF printed on your old capacitor rather than relying on the model name alone. Our DAB Aquajet 112M capacitor guide has more detail for this pump.
How a weak capacitor shows up
- The motor hums when it is switched on but the shaft doesn’t turn.
- It starts if you flick the fan or shaft by hand, then runs slow.
- The thermal overload trips after a few minutes of running, or the motor feels much hotter than usual.
- The old capacitor is swollen, cracked or leaking oil.
Other pumps listed with a 25 µF capacitor
The same 25 µF 450 VAC rating is listed for the AstralPool CTX, DAB Aquajet 132M, DAB K12/200, Grundfos JP6, Onga Pantera PPP1100 and Onga Pantera PPP1500. It is also sold as a plain 25 µF 450 V CBB60 capacitor.
If the Aquajet 112M is also dripping at the shaft, the DAB Aquajet 112M service kit pairs this capacitor with the 13 mm mechanical seal, and the Aquajet 112M seal is also sold by itself.
Fitting the new capacitor safely
Switch off and unplug or isolate the pump before opening the terminal box. A capacitor can hold a charge after power is removed, so treat it as live and discharge it across its leads with an insulated tool before handling it. Take a photo of the wiring, then connect the core leads of the new capacitor where the old ones went and secure the body where the old one was mounted. If you’re not comfortable working on mains wiring, have an electrician fit it.
Before you order
Check the old part before fitting: match the µF printed on your old capacitor.
