Capacities vary by pump type and model. Small reservoirs commonly list sizes of about 3 L, 7.5 L, and 10 L. Shop oil drain pans are often 17–20 gallons. Drum pumps are sized to fit standard drums and are described to work with 5–55 gallon drums. Actual holding or handling volume depends on the specific product.
Performance varies by type. Manual lever-action drum pumps have reported stroke volumes around 9.5 ounces per stroke, while cordless electric siphon-style pumps are described as delivering up to about 2.5 gallons per minute. Exact flow depends on the pump design and model.
Descriptions list broad compatibility for many pumps, including gasoline, oil (including ATF), water, windshield washer fluid, engine coolant/antifreeze, brake fluid, DEF, and some corrosive liquids. Compatibility varies by model—one drum pump listing specifically advises against use with diesel, kerosene, engine oil, or gasoline—so always check the product’s stated compatible fluids before use.
Kits commonly include multiple metal ATF fill adapters and a selection of hoses. Listings frequently mention adapter packs of roughly 8 to 14 common adapter fittings, plus outlet or auxiliary hoses of varying lengths to fit different fill ports.
Typical materials include plastic reservoirs made from polypropylene (PP), ABS, or HDPE, steel for drain pans and structural parts, and metal components such as brass valves and metal adapters.
Manual pumps typically use a dual-control system with two-way valves and a flow-direction control (often a blue screw knob). Turning the flow-direction valve redirects the internal pathways so the pump either extracts fluid from a reservoir or dispenses it to a target.
