16-Stage Cast-Iron Booster Cartridge

The Flint & Walling 138447 is a 16-stage cast-iron impeller cartridge designed for PB-series booster pumps. It replaces the internal stage assembly in compatible models and includes two O-rings, a coupling, a discharge bearing, a shaft and all stage components.

Drop-in replacement for PB-series pumps

This cartridge fits Flint & Walling booster pumps with manufacturer model numbers PB0516A071 and PB0516A073. It restores original hydraulic performance without modifying piping or mounting hardware, freeing the installer from sourcing individual wear parts.

Cast-iron construction for continuous duty

The all cast-iron stage stack resists corrosion and erosion in aggressive water conditions. With 16 stages the cartridge develops the pressure head the pump was rated for, while the supplied O-rings and bearing maintain seal integrity and low vibration during extended operation.
