Poolaroo Pro Tip

Bronze volute construction is specified for C Series commercial pumps because bronze resists the corrosive effects of continuous high-flow, high-cycle commercial operation better than composite materials. When replacing the volute, inspect the impeller and mounting hardware for wear at the same time — a worn impeller paired with a new volute can cause uneven clearance and reduced flow performance.
