Supply Planning
Plan samples, first orders and repeat supply for an engine water pump as separate decisions. Compare impeller and housing supply boundaries before locking replenishment.
Agree sample identity for the engine water pump: impeller material and rotation, housing casting, seal package and whether pulley or gasket pieces ship with the sample. Record which mounting dimensions and leakage checks will be inspected before any production lot is released.
Confirm quantity, packing by piece, accepted specification revision and whether housing or impeller substitutions still need buyer approval against the engine cooling circuit.
Keep pump references, agreed substitutions, seal revision and reorder MOQ visible. Replenishment should not silently change impeller geometry or port orientation.
Ask for disclosure when housing material, impeller, seal, connector or production source changes, even if the commercial name stays “engine water pump”.
Sample-to-replenishment planning is useful for early ordering, but buyers should still list engine code, drive form and port sizes. Waterdrive Sourcing will not treat a catalog family name as proof of fitment, stock or cooling performance for a specific vehicle program.
