Aluminum Pump Housing Manufacturer
Bohua supplies custom aluminum pump housings and casings with casting, heat-treatment and CNC machining scope agreed from your drawing. Review existing component examples and the inspection requirements for your fluid path and sealing interfaces.
Based in Ningbo, China, Bohua reviews new tooling and supplier-transfer projects for industrial and automotive components. Specify whether you need a casting blank or a finished machined housing so the quotation covers the correct delivery condition.
Bohua has two low-pressure casting machines in trial production. Part suitability, sample validation and production readiness require project-specific review before an order is accepted. Bohua does not offer sand casting.
Pump housing and casing examples
Review the listed geometry, material and process as a starting point for discussion. Each new part needs its own drawing review, acceptance requirements and quotation.

For the application and functional interfaces, see the pump housing application guide.
Plan the fluid path, seal chamber and machined interfaces together
Fluid wall and internal passages
Identify the pressure boundary and sections near the machining envelope.
Verification: Agree the internal-inspection zones and pressure or leak-test procedure.
Seal chamber and bearing bore
Define their relationship to the assembly datum, including the final machining state.
Verification: Request a dimensional report tied to the drawing datum scheme.
Flange, gasket face and ports
Provide the mating interface, sealing requirements and threaded-port details.
Verification: Specify dimensional, surface-finish and thread checks where required.
Mounting features and protection
Identify mounting datums and surfaces that must survive handling and shipment.
Verification: Agree final visual checks, cleaning and protection of machined surfaces.
A drawing-specific tolerance or test requirement takes precedence over a general process description. For an observed pore, crack or leak, use the casting defect investigation guide to separate symptoms from causes. For the detailed interface review, see the seal-chamber and bearing-bore inspection guide.
Agree the casting and machining scope
Identify whether Bohua supplies an as-cast component, a heat-treated blank or a finished machined part. Review material, tooling and casting allowances before defining the CNC datum and inspection plan.
- A356 material and temper: confirm the specification and required test evidence.
- Gravity casting: review geometry, cores, feeding and machining stock.
- Casting plus CNC machining: define final features and delivery condition.
Evidence to review with Bohua
The confirmed equipment list includes Oxford OES, Unicomp UNC-160 and Y.MU2000-D X-ray systems, and Hexagon Global S and NANO Metrology CMM systems.
Bohua has its own pressure-tightness testing workshop. Test method, medium, pressure, duration and acceptance criteria are defined according to customer drawings and project requirements.
PPAP documentation can be provided up to Level 5 according to project requirements.
Pump housing manufacturing questions
Does Bohua supply raw or machined pump housings?
The delivery scope can include casting, heat treatment and CNC machining as agreed for the drawing. State the delivery condition and identify finishing, cleaning, inspection and packaging requirements before comparing quotations.
How is the casting process selected for a pump housing?
The review considers alloy and temper, internal passages, wall transitions, machining stock, quantity and acceptance requirements. Gravity casting is reviewed against the actual geometry. Bohua's low-pressure machines are in trial production and require separate validation; the part name alone does not determine the route.
Does a pump housing quotation include complete-pump performance testing?
A housing quotation covers the agreed component scope. Define which pressure or leak checks apply to the casting or machined housing and which performance or approval tests remain with the pump assembler.
Can I verify inspection capability before releasing drawings?
Bohua has its own pressure-tightness testing workshop. Test method, medium, pressure, duration and acceptance criteria are defined according to customer drawings and project requirements. Review the quality-control and certificate pages, then request the records and equipment scope relevant to your part. Confidential drawings should follow the agreed NDA process.
Discuss your pump housing drawing
Send the part number, drawing revision, material requirement, quantity and delivery condition. Identify the functional interfaces and tests that determine acceptance.
