Grundfos CM 10-3 — material number 97524349 — is a 3-stage Grundfos CM vertical multistage centrifugal pump with a 5.4 HP, 3-phase, 208-230/440-480 V NEMA TEFC motor and a HQQE shaft seal.
This 3-stage configuration produces a moderate 135 ft of head at the BEP (60 GPM, ~58 psi) and is the most common choice for low-rise commercial boosting and short pipe runs where modest pressure is needed.
