Pump housing/casing is the main structural component that encloses and supports the internal elements of a pump assembly, providing pressure containment and fluid flow guidance.
The pump housing or casing is the primary structural element in centrifugal, positive displacement, and other pump types that forms the pressure boundary containing the pumped fluid. It houses the impeller, shaft, bearings, and seals while directing fluid flow through designed passages (volutes, diffusers). Casings withstand internal pressure, external loads, and provide mounting interfaces for piping and support structures. Materials and design vary based on pressure ratings, fluid compatibility, temperature, and corrosion resistance requirements.

Volute casings have a spiral-shaped passage that gradually increases area to convert velocity to pressure, while diffuser casings use stationary vanes around the impeller for more efficient pressure recovery in high-pressure applications.
Material selection follows ASTM standards based on fluid chemistry, temperature, and concentration. Common choices include stainless steel (304/316) for mild corrosives, duplex steels for chlorides, and nickel alloys for severe services. Always consult corrosion charts and conduct compatibility testing.
Primary failure modes include corrosion/erosion from abrasive fluids, thermal stress cracking, mechanical fatigue from vibration/pulsation, casting defects (porosity, inclusions), and improper installation stresses. Regular inspection and proper material selection prevent most failures.
