Bell & Gossett P42258 Volute Pump Casing Assembly

Bell & Gossett P42258 Volute (pump casing) for Series 1531 2AC end-suction pumps is an OEM replacement part crafted in cast iron to form the outer housing around the impeller and direct fluid flow from inlet to discharge. This volute is rated for 125 psi and is specified for Bell & Gossett 1531 2AC models, ensuring compatibility with the original pump and preserving established performance characteristics. It is designed to replace a worn or damaged volute in the pump assembly and to mate with the corresponding bearing frame and seal components of the 1531 2AC series, helping maintain proper alignment and sealing during service. Because it is a genuine replacement part, it supports retrofit and repair projects on 1531 2AC pumps, enabling continued operation without requiring a full pump replacement. The P42258 volute integrates with the pump’s mounting pattern and fluid path to restore the intended flow characteristics and reliability of the original equipment.
