Picked up a Haskel model 83354 R600 transfer pump, looks like somebody sucked hash into this thing and ran it for a while after, so once I’m done cleaning everything up going to have to reseal kit it.
From what I can tell from the Airline website HASKEL EXT420 | Airline Hydraulics and the FLW website for this pump here: Haskel EXT420 Single Stage R600 Butane Extraction Pump - FLW, Inc. and a drawing that page links to here: https://store.flw.com/content/100962/93727/haskel-r600-butane-transfer-pump-ext420-product-drawing.pdf , the 83354 model is (maybe?) the pump upon what the EXT-420 models were built, unlike newer EXT models this one doesn’t have the valve and plumbing to select parallel/serial pumping modes, not that I would expect that matters wrt the seals inside the hydrocarbon pumping side of the pump
Haskels website doesn’t list the 83354 model nor the EXT420 in their seal kit selector under the spare parts page as far as I can tell. Airline’s website shows a few different seal kits, can anyone confirm that 29017 is the correct seal package for the gas side of this pump? I used Haskels contact form on their website last week and still haven’t got a response, would feel a little better if the kits on Airline’s website were labelled better. Don’t want to order an air end seal kit when I need the gas end
