The Pump Cartridge on Your Weil-McLain Boiler

Many circulators (notably Taco and Grundfos models) use a replaceable cartridge that contains the rotor, bearings and impeller. Swapping the cartridge restores the pump without replacing the whole flanged body — a fast, economical repair.

On Weil-McLain systems — including models such as ECO, ECO Tec, Ultra — a failing pump cartridge often shows up as low water cutoff trip or related symptoms. We diagnose it precisely and install the correct genuine Weil-McLain part.
