Revainrating 4 out of 5

Does the job, cheap and versatile.

You get pretty much what you see in the product photos, although I really didn't expect a manual to come. The materials used are fairly cheap, but it's well constructed so the important parts are solid enough; The jug is nice and thick, the rubber stopper is strong, the pump works. The two included suction tubes, a hose clamp, and a free funnel are downright cheap, but given the price ($15) that's to be expected and not particularly heavy or expensive components anyway. I've used this thing to pump motor oil (1 liter, room temperature) out of a small engine for 3 minutes with no problems, so I can only assume that other reviewers with flow issues have either a leaking pump or something wrong. To that end, I'll post some tips on how to properly use such an aspiration pump below.・Test your pump with water when you receive it to check for manufacturing defects. Water is the easiest liquid to clean when you need to return or replace your pump.・With a few exceptions (e.g. toothpaste), the viscosity of the liquid will only slow the flow, not stop it. This means you can simulate almost any water tank pumping situation as long as the multiplicative flow rate penalty is enabled for more viscous liquids. If you find that you cannot pump a more viscous liquid at all after testing a similar setup with water with the same suction power, check for other factors that may affect flow (e.g., air leakage through unsealed gaps, leaking pump). If you're trying to suck molasses through a coffee stirrer, don't expect even that pump's theoretical maximum pressure of 1 atmosphere (in practice, either the jug or the suction tube will collapse first) to get the job done in a reasonable amount of time. the supplied suction hoses are quite long (≥1 m) and rigid. Don't kink them or you'll break their structure and they'll snap if you try to pull too much vacuum through them. ・ Do not use the supplied hose clamp on the suction pipes (ignore the instructions), they may be kinked. .・The suction hoses go all the way through the inlet on the plug and into the container. This prevents the pumped medium from coming into contact with the plug. You'll have to apply quite a bit of pressure (and possibly twist) to push the hoses through the plug.・Of the two suction hoses, the larger one's OD is 10.0㎜. The plugged inlet accepts 9.0 x 10.0 µm OD tubing (and is properly sealed). This is the end that goes through the inlet of the plug.・The suction hoses are rolled up, which is probably quite inconvenient. To flatten them, gently heat them by either running hot water through them or blowing them on with a hair dryer, then either pass them through with wooden dowels or metal rods, or mount them with a rubber stopper and jug (⅛⅓ with filled with water). , leave the pump off in case of failure) and hang the whole contraption on something at the other end of the tube (see pictures). Let the pipes straighten for at least a day. They won't stay straight, but it's much more comfortable to work with.・Use a large suction tube if it fits; You'll get a much better flow.・The rubber stopper is tapered to fit snugly around the jug, so it will work with any container that seals with a round hole between 36.2 and 51.4 microns in diameter. If the supplied jug is too small for your application, you can find a larger jug.・The pump can be unscrewed from the rubber stopper, but is otherwise encased in a plastic case and cannot be disassembled for service (as far as I can tell).・Do not pump with this system unless you are certain that what you are pumping will not exceed the capacity of the jug. I'm lucky that soapy water washes out of the pump easily. When in doubt, keep the bottom of the stopper above the level of the liquid you are pumping.・The higher the jug, the harder the pump works. Try to hold the pitcher as close as possible to the container you are siphoning water from.・Be patient. Once liquid begins to flow into the jug, use the resistance you feel while pumping as a gauge to maintain suction. Pumping uncontrollably to increase flow also increases the chances of your jug or suction tube breaking. ・Be careful when pumping liquids warmer than room temperature (e.g. to be removed sooner).・Unplug the jug and wipe the end of the suction tube (which protrudes through the plug) clean before unplugging it remove to prevent liquid residue from contacting the stopper.・Clean at least the rim and inside of the neck of the jug before replacing the stopper to prevent liquid residue from contacting the cork.・I have Don't plan on using this product much but rest assured it hasn't broken yet, I'll update this if it does.
