Fire pump wear ring
Define the geometry, material, delivery condition and acceptance criteria for the selected application. Manufacturing scope requires review of the approved drawing and operating requirements.
COMPONENT GUIDE
Fire pump wear ring
Drawing-defined replaceable clearance interface between impeller and casing
Provides the specified replaceable ring at a pump running-clearance interface.
Manufacturing & delivery form
Ring-shaped casting blank or machined bar/tube stock, as agreed.
A pump wear ring is not a mechanical-seal face ring. Material, clearance and mating surfaces must be reviewed together, including standby duty.
Component RFQ requirements
- Ring geometry
- Define inside/outside diameters, width, steps, retention and machining allowance.
- Running fit
- Specify the OEM clearance, mating-ring material, hardness relationship and temperature basis.
- Geometric acceptance
- Provide roundness, concentricity, surface finish and drawing datums.
- Water and operating duty
- Identify water chemistry, rotating speed, standby/start conditions and any wear concern.
- Approved supply form
- Confirm cast blank or stock route, final machining, material records and OEM replacement approval.
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.
