Replacement Options

As titled, this great range of Grundfos Pump has been discontinued, however two modernized, improved versions of this range has taken its place. The Grundfos CMB/ CM Booster range, as well as the CMB/ CM Booster SP (Self Priming) range. The proper replacement pump largely depends on your setup and your Grundfos CH model you’re trying to replace. The CM Booster range cannot self prime (it is not made to suck water from below it/has the ability to self prime) where-as the CM Booster SP range can, so depending on where your current pump is located (above, inline or below) would determine which range would suit you best. Another factor with finding a great suitable replacement for your pump is that the Grundfos CH range was quite large, there were multiple versions that could deal with different amounts of water & at different pressures. The CM Booster / CMB range only has a few model choices, whereas the CM Booster SP / CMB SP range has several options, giving you a more accurate like-for-like replacement.
