COMPONENT GUIDE

Pump casing / housing

Pump pressure boundary

Forms the flow passage and interfaces around the impeller.

Manufacturing & delivery form
Complex casting with drawing-defined interface and sealing-face machining, subject to review.

A casing is a component, not a complete pump. High-pressure RO service requires a separate material and design review.

Material candidates

UNS C90500 Tin bronze

A candidate for drawing-specified pump, valve and friction components.

Candidate for drawing review only. Confirm medium, loading, manufacturing condition and the governing standard. Zhiren availability is unconfirmed.

UNS C83600 Leaded red brass

A candidate for specified pump, valve and fitting castings.

Candidate for drawing review only. Contains lead; potable-water suitability must not be assumed. Zhiren availability is unconfirmed.

UNS C95800 Nickel aluminium bronze

A candidate for specified saline-water and wear components.

Candidate for drawing review only. Review water chemistry, flow, mating metals and casting condition; no corrosion or cavitation guarantee. Zhiren availability is unconfirmed.

UNS C89833 Bismuth tin bronze

A candidate low-lead alternative for specified wetted components.

Candidate for drawing review only. Composition alone does not establish final-product approval; confirm the OEM specification and required evaluation. Zhiren availability is unconfirmed.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Flow passage: Model, flow-path geometry, wall sections and machining allowances.
Interfaces: Suction/discharge connections, flange or thread standard, cover register and sealing faces.
Water & testing: Actual water composition, design pressure and temperature, defect criteria and agreed leak-test responsibility.
Material specification: Alloy grade, governing standard and revision, manufacturing condition and any restricted substances.
Order & acceptance: Approved drawing revision, quantity, blank or machined delivery, inspection criteria and required records.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.
