Is this single- or multi-pump?

It is single pump. It is a break barrel. Uses a spring to pressurize the air.

It's a break barrel, when you break the barrel open to loaded it, it pressurize the chamber at the same time, This gun will outperform any multi pump, with the right pellet you can shoot through steal, and this thing is quite you can shoot it in your backyard without any concerns, I highly recommend this gun to friends

The pump is separate. Works fast and easy, and sleeps quite well. I have two aerobeds for company and I put an inexpensive egg crate topper on them. Everyone tells me that they are super compy and sleep great!

Metricspork answered and the answer is yes. I am using 1 now and the pump keeps up and produces 40 psi.

When I ordered it it came with two. The kit is for a single pump and like you said it needs two.

Good question, ask Beckett. The sad reality is that most nozzle attachments only fit one pump, even when they come from the same manufacturer. My advice is do not buy a pump unless it comes with its own nozzle attachments. It has been a frustration for me for years.

You can pump one at a time. The Ameda has a little plug to keep the air from going down the other tube. I single pump a lot of the time.

It is only plug in.. However when I used my one time in January of 2013 I cleaned it put it back in box stored it to December 2013 plugged it in and pump would not come on ..ended up throwing in trash after one use. But wasn't a lot of money so I didn't feel to bad.

This pump is hydraulicaly operated. Its not electric. You have to connect all the ports in it. You cannot leave ports unconnected. Google permeate pump connection schematic and Im sure you'll find a good schematic.

One pump, it does not last long at all because the bottle is not full & it is over price for the amount u get.

This is not a pump or a 12 volt powered system. It is a buffer so that the pump doesn't short cycle quickly. It evens out the pump so it stays on for a while and then shuts off until the pressure drops to a level you set by pumping air into it to your chosen pressure. It comes factory pre-set with compressed air. I would like the 1 gallon one but don't have room for it. This tiny one at least makes the pump run for a while and then briefly stop until it comes on again.

It's a manual pump but it's pressurized pretty well so you really only need one pump to get a cup of water. Also, it takes a bit of force to push down on the pump itself.

What do you mean by double electric? It runs off of either the battery pack (8 AAs) or the AC wall adapter. It can pump one or both breasts at once.

What exactly do you mean? If a double pump, than yes. My pump was provided by insurance, with no model name, but that attachment worked well.

This may be better answered by the supplier, however this is the pump I received. Hated it. Spend your money on an electric one if you can. This thing did nothing.

There is no adapter, there are 2 places to plug the tubes into- you simply remove the "clear plastic top" off of the bottom hole on the bottom of the machine. If you want to dual pump just plug each tube into the holes on the front of the machine- when you only want to pump one- just replace the "clear plastic top" back. Also note, this clear plastic will not fall off it is attached to the machine. I think the instructions in the box are out dated. I hope this helps.

I have had two and both worked well. Is it compatible with the model pump that you are using? Are you sure it is plugged in properly?
