Air-operated double-diaphragm pumps are workhorses for waste oil transfer, but deciding between two entries for the same model can feel redundant. The tricky part is finding the same pump model at two different listed prices and deciding whether the extra cost changes anything. The two options here share the exact same title, component set, and dimensions. That makes this a price comparison rather than a feature comparison.
Quick verdict
The AODD Pump 1/2" Port 12 GPM Industrial Pneumatic Waste Oil Transfer Pump | Durabl appears at two listed prices. Both list the same included component set, flow rate, port size, color, condition, and dimensions. Because the specifications match, the decision comes down to the listed cost.
Listed-price and spec snapshot
| Option | Listed price | Price bar | Shared specs |
|---|---|---|---|
| AODD Pump 1/2" Port 12 GPM (USD 226.23) | USD 226.23 | QBK-15 AODD pump, 1/2-inch inlet/outlet, 12 GPM, White, New, MPN 167155-2 | |
| AODD Pump 1/2" Port 12 GPM (USD 220.84) | USD 220.84 | QBK-15 AODD pump, 1/2-inch inlet/outlet, 12 GPM, White, New, MPN 167155-2 |
Where each product wins
The higher-priced entry offers the same listed specs as the lower-priced entry. It doesn't add a different component, flow rate, or port size, so there is no feature-based win to assign here.
The lower-priced entry wins the cost comparison. It lists the same product name and same specs while asking for a smaller amount.
Product notes
AODD Pump 1/2" Port 12 GPM Industrial Pneumatic Waste Oil Transfer Pump | Durabl - higher listed price
This entry is for the AODD Pump 1/2" Port 12 GPM Industrial Pneumatic Waste Oil Transfer Pump | Durabl. It includes the QBK-15 Air Operated Double Diaphragm Pump with a 1/2-inch inlet and outlet, and it's listed as New in White with a 12 GPM flow rate. The item dimensions are 6"L x 4"W x 10.6"H, and the manufacturer part number is 167155-2. The reason to choose it is if you want the complete listed package under this product name. The limitation is that the listed price sits above the other entry, and the listed specs don't show an added component or higher flow rate to account for the gap.
AODD Pump 1/2" Port 12 GPM Industrial Pneumatic Waste Oil Transfer Pump | Durabl - lower listed price
The lower-priced version is the same AODD Pump 1/2" Port 12 GPM Industrial Pneumatic Waste Oil Transfer Pump | Durabl. The listed specs match the higher-priced entry, including the included pump, port size, flow rate, color, condition, and dimensions. The reason to choose it is straightforward: the listed cost is lower, and you still get the same included component set. The limitation is that the lower cost doesn't bring a different specification-the model, flow rate, port size, and included pump match the other entry, so the comparison is about price rather than performance.
Final choice by use case
If the priority is the listed price, the USD 220.84 entry is the direct choice. If you specifically want the USD 226.23 price point, you'll get the same listed pump model and component set-the difference is USD 5.39 in the listed cost, not in the pump. The choice is simple: pick the entry with the lower listed price unless you have a specific reason to stay with the higher-priced one.
