Yamada 3" sc414 Stainless Steel Air Powered Double Diaphragm Pump

I received a bunch of these type pumps in. They are in great shape but no badges that I could find. I matched up the picture and size with a Yamada NDP-80BST-NPT, but as no expert and no badge...can not be sure. I know it has SC414 meaning Japanese Stainless steel from stamp on body. Feel free to ask any questions and I will try to get answers for you.
