When you need a reliable air-operated double diaphragm pump for waste oil transfer, the listings can look deceptively similar. In the industrial pumps flow control space, this AODD Pump 1/2" Port 12 GPM appears twice in the same search results, and both carry the same specification sheet. The only difference is the listed price: one is $220.25 and the other is $220.84. So which one should you add to your cart? This head-to-head review isolates what actually changes between the two listings.
Quick verdict
If you are choosing strictly between these two listings, pick the one with the lower listed price. The pumps are identical in every listed attribute, so the lower-price listing gives you the same AODD pump without paying the extra 59 cents. There is no functional reason to choose the higher-priced listing.

Where each product wins
- Lower-priced version: Wins on the lower listed price, which is $0.59 below the other listing.

Product notes
AODD Pump (USD 220.25)
Choose this listing if you want the same AODD pump as the other listing but at the lower listed price of $220.25. The pump is listed as new and is identified by manufacturer part number 167155-2. The included QBK-15 air operated double diaphragm pump is part of the package. The limitation is that you won't get any functional advantage over the higher-priced listing. Because the specs and included components match, your only benefit is the lower price.
AODD Pump (USD 220.84)
This listing provides the same pump in new condition with the same included QBK-15 air operated double diaphragm pump. If you want that pump and the price difference is not a deciding factor, this listing will meet the need. The limitation is the higher listed price. There is no stated extra value in choosing this one, so the higher price is the only reason to look elsewhere.
Final choice by use case
For any use case that calls for a pneumatic waste oil transfer pump with 1/2" connections, the lower-priced listing is the better pick because it delivers the same pump at the lower listed price. The higher-priced listing is not a different product; it is the same AODD pump with a slightly higher price tag. Go with the lower-priced listing and you will get the new QBK-15 pump and the same flow performance without paying the extra amount.
