304 stainless steel is a practical option for general industrial pump components. For applications requiring better resistance to chloride-containing environments, 316L may be a more suitable choice.
The final material should be selected based on the fluid, temperature, operating conditions, and cleaning requirements.
The position and size of internal bores are important for shaft, bearing, and seal installation.
We focus on bore diameter, concentricity, and alignment with the specified reference surfaces to support accurate assembly.
Pump housings often have gasket faces, mechanical seal interfaces, and O-ring grooves.
These surfaces need suitable flatness and surface finish. Even a small burr or machining mark across a sealing face can create a leakage path.
We machine flanges, bolt patterns, threaded holes, locating shoulders, and mounting faces according to customer drawings.
This allows the housing to fit the existing pump assembly without unnecessary changes to surrounding components.
Different pumps require different internal cavities, wall thicknesses, inlet and outlet positions, and mounting arrangements.
We review these features during manufacturing planning, especially where internal passages are difficult to machine or inspect.

At Hofengfab, we support custom pump housing manufacturing with CNC machined bores, sealing surfaces, and mounting features based on customer drawings.
