Choosing a 12 GPM air-operated double-diaphragm pump for industrial waste oil transfer comes down to more than just flow rate: you want the right port size, included components, and a listed price that fits your budget. But when two listings describe the same pump, the decision gets simpler - you just need to identify whether paying more gets you anything extra.
Quick verdict
Both listings describe the same QBK-15 air-operated double-diaphragm pump with a 1/2" inlet and outlet, 12 GPM flow rate, white color, new condition, and identical included components. There is no listed difference in specs, accessory kit, or dimensions. So the better buy is the listing at USD 220.84 - you pay USD 5.39 less than the other listing while getting the same pump. The USD 226.23 listing is only worth considering if you specifically need the GTIN 7445011851860 or prefer that particular listing.

Where each listing wins
- Lower listed price: The USD 220.84 listing wins on price. It shows the exact same pump and included components as the other listing, but with a lower listed price.
- Specific GTIN: The USD 226.23 listing matches GTIN 7445011851860. If you need that particular identifier for an inventory or procurement record, this is the listing that corresponds to it. No other spec difference is listed.
Both listings share the same white color, new condition, 12 GPM flow rate, 1/2" ports, and identical included components. So outside of price and GTIN, there is no practical difference between the two.
AODD Pump 1/2" Port 12 GPM (USD 220.84)
If you're looking for a 12 GPM air-operated double-diaphragm pump for waste oil transfer, this listing gives you the QBK-15 pump with 1/2" inlet and outlet at the lower listed price. It includes the pump and the standard included components, and everything else matches the higher-priced listing: white color, new condition, and the same 6"L x 4"W x 10.6"H dimensions. The limitation is that there are no extra accessories beyond the pump itself, so if you need additional fittings or hoses, you'll have to source those separately.
AODD Pump 1/2" Port 12 GPM (USD 226.23)
This listing describes the identical pump and included components as the lower-priced one, so it's a candidate if you're specifically looking for the GTIN 7445011851860 version. It also confirms the same 12 GPM flow rate and 1/2" ports, so it will perform the same job in an industrial waste oil transfer setup. The limitation is that the listed price is higher than the other listing, and you receive the same included components without any extra items to justify the difference. If you don't require the specific GTIN, the lower-priced listing gives you the same pump for less.
Final choice by use case
For almost every buyer, the USD 220.84 listing is the better choice because the specifications are identical and the price is lower. The only reason to choose the USD 226.23 listing is if you specifically need the GTIN 7445011851860 or prefer that particular listing. Otherwise, pay USD 5.39 less and get the same pump.
