What Is a Water Pump Flange ?
A water pump flange is a mechanical installation part that links the water pump to an engine, housing or plumbing connection. It offers a secure interface for the pump shaft or impeller and maintains the seal that prevents coolant from leaking through the system.
In automotive and machine applications, the flange usually has been machined to precision tolerances and is constructed of material such as cast iron, steel, aluminium or a powder metallurgy alloy in order to provide high strength and dimensional stability. This generally has bolt holes, a hub or bore for the pump shaft and a surface on which seals such as gaskets or O-rings are to be sealed against.
The water pump flange is fitted in position and provides a stable coolant flow with no leaks while connecting the pump to bearing structure to facilitate effective thermal management across engines and industrial cooling systems.
How Water Pump Flanges are Made by Powder Metallurgy?
Water pump flange production begins with mixing iron-based powders such as FC-0205, FC-0208, or FN-0205 with zinc stearate or lithium stearate. These binders improve powder flow and compaction performance. The mixed powders are subsequently pressed into a precision multilevel die at 400–800 MPa, resulting in formation of the green compact (the geometry of flanges, position the bolts and surface for sealing).
For the ferrous material, the green compact is sintered in a controlled atmosphere furnace at approximately 1120 °C. Under the sintering process, solid state diffusion bonds the particles and density, strength and design stability are gained that turns the compact into a fully functioning water pump flange.
Sizing and machining are performed after sintering to final tolerances and finish. Frequent surface treatment such as steaming, Dacromet coating and electroplating can be used to improve anti corrosion ability of fastener.

Sintered Water Pump Flanges Benefits
High Raw Material Utilization
Sintered flanges are compacted from metal powder to achieve a net shape, reducing the need for further machining process.
Tight Tolerance
The tolerance of water pump flange can reach between IT6 to IT7 after sizing.
Cost-effective in Mass Production
Powder metallurgy water pump flanges are cost-effective in mass production due to fewer processes and higher material utilization.
Batch to Batch Quality Consistency
Water pump flanges have good quality consistency between different batches.
Wide Range of Surface Treatments
Dacromet
Dacromet is a water-based, chrome-free coating made from zinc, aluminum flakes, and a binder. Water pump flanges are cleaned, coated by dipping or spraying, then cured to form a protective layer.
Anti-rust oil
Sintered flanges can be oil-soaked to prevent rust for up to one year.
Galvanizing
Sintered flanges have pores inside, which need to be filled before electroplating, and then a layer of zinc is applied by electroplating.
