The Pump Cartridge on Your Lochinvar 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 Lochinvar systems — including models such as Knight, Knight WH, Noble — a failing pump cartridge often shows up as ignition lockout or related symptoms. We diagnose it precisely and install the correct genuine Lochinvar part.
