Why are the valve discs and seat of multi-plunger diaphragm pumps so expensive? What material are they made of? Is 700 yuan needed for something that small?

Pumps aren’t expensive in themselves; what’s costly are the repair parts. A diaphragm pump. Thousands is possible. Aren’t you buying it? Whatever. It’s really amazing.
