The mechanical seal is a key sealing element of every circulation pump – as soon as it starts to leak, it is time to replace it. This replacement seal is precisely dimensioned for Basic series pumps and guarantees a precise fit without leaks.
Replacement is accessible even to an experienced DIY enthusiast: simply remove the front part of the pump, replace the seal and reassemble. A properly seated seal protects the motor bearings from moisture and prevents water dripping under the pump.
We recommend checking the seal every 2–3 years or immediately at the first signs of seepage. The original dimensions and material ensure compatibility with the original pump assembly.
