The UnitedBuilt H04007MS mechanical-seal bearing frame is a cast-iron replacement frame for the M3ZRMS pump arrangement. It supports the bearing-frame portion of the pump and is selected by the mechanical-seal configuration, not simply by the 4x3 pump size.
Choose H04007MS when replacing the mechanical-seal frame. This is the frame component, not a complete powerhead; the shaft assembly, bearings, impeller and seal are separate repair components.
The mechanical-seal frame differs from the H00553MS rope-packing frame. Matching that distinction before ordering helps prevent combining the wrong frame and sealing components. Check the existing pump model and frame number before planning a replacement or a broader rebuild.
