I have a Yamada NDP-25BSH Diaphram Winery Pump that I bought last year from Bosa. It's maybe seen use once a month (so used about a dozen times). It's in pretty much new condition. Always cleaned and sanitized after each use. I bought it for $5k so looking to sell it for $3.5k. Located in Victoria, BC. Email me if interested: firstname.lastname@example.org
UPDATE: Sept 7, 2021 - Still available! Price reduced from $4k to $3.5K
Runs on compressed air
46.2GPM max output
Comes with 1.5" TC fittings, expansion chamber, exhaust, air filter and regulator, and cart.
Yamada's product guide can be found here: https://www.yamadapump.com/assets/literature/guides/Yamada_2018_US-ENG_Product_Guide.pdf
On pages 2-4 you will find some general information on Yamada Pumps, and on pages 12-13 you will find information specific to the NDP-25 pump. You can see on page 13 it has "model number nomenclature" this pump is a NDP-25BSH so the S would represent a Stainless Steel body.
