This is a 224-350 stainless pump powered by the 205-997 air motor. This is one of two pumps we are selling on eBay and this video was posted for the benefit of potential buyers.
The pump was temporarily setup with a simple airline connection just to make sure it cycled properly prior to posting it for sale.
The other unit we are selling uses the same air motor but has a 218-956 pump. We haven't posted a video but it cycles in the same manner as the one shown here.
