Abstract

In at least some implementations, a method of forming a diaphragm for a liquid pump, includes clamping a substantially planar piece of material about a periphery, and plastically deforming the piece of material inboard of the clamped periphery. In at least some implementations, the material is plastically deformed by pressing a forming member against the material, or the material is plastically deformed by applying a fluid under pressure against the material.
