A repair kit (also called a service kit) for the DAB K-Series K14/400 pump: seal, bearings & capacitor in one order. The same parts fit the K55/50. Where the K-Series models differ: the K20/41 uses a different seal (13 mm shaft); the K14/400 takes a 40 µF capacitor where the K20/41 takes 10 µF; the K12/200, K30/70 and K35/40 take 20 µF; the K30/100 and K45/50 take 30 µF; the K12/200, K20/41, K30/70, K35/40 and K36/100 use a different motor bearing set.

What’s in the DAB K14/400 repair kit
Why service the K14/400 in one go
- The seal is the part that wears out on a pump: once it weeps, water heads for the motor.
- The motor is already off the pump to change the seal, so it’s the easiest time to change the bearings.
- The capacitor is a quick swap while you’re working on the pump, and if it has been slow to start, the capacitor is the first thing to check.
Before you order
Check the old parts before fitting: match the µF printed on your old capacitor and the size of your old seal.
