does this pump shut off when a certian pressure is reached? in other words does it opperate on demand? thanks

If I understand your question, you're asking if this pump shuts off automatically when the water level drops and it starts sucking air. The answer is no, it runs as long as you are providing power to it. Pull the plug, and it quits.

It does NOT operate on demand. Plug it in and it runs. Remove the plug and it shuts off. As long as you have it in water the suction remains constant. Having said all that, I love this pump. My only problem is that it is sooo heavy. I use it mainly to empty my 150 gal fish tank prior to cleaning and to empty my grandchildrens' 15' swimming pool every Fall. I just attach a long hose to the pump and water my garden flowers until the pool is empty. Only once did it give me a problem and that was when I took the protective screen off the intake and it sucked up a large piece of gravel from the fish tank. Something broke inside. But my son went up to Lowe's for a little part and it was good as new. You must remember to prime it before use by putting some water in it. I would definitely buy another one if necessary but I wouldn't be surprised if it outlived me. I'm 70. I suppose that what you would use it for would determine how well it would work for you. For me it's perfect. Good luck.

The best thing is to have a ball valve installed in the line that you close off first before turning off the pump. The reason for not shutting it off, is the vacuum you just pulled will suck oil back from the pump back into whatever you just pulled the vacuum on if you just turn it off without some sort of shutoff valve. BTW, some pumps have this valve built in. This one does not.

Pretty good. It continues a strong boil for several seconds before shutting off. Unless you overfill it, then the unit continues to boil for a while. I suspect it would continue to boil off water until it drops to the max fill line, but I've never tested that theory. If I accidently overfil it, I usually manually shut it off. And it does not shut off, just because you pick it up off the base.

It shuts off when the reservoir is full, but not when the desired temp is reached. However, it is very quiet, so you don't notice that it runs constantly.

I have not had it shut off It has run dry - pumping for several hrs with no problem

Yes, it shuts the unit down when water pressure drops. We used it for a pool and when the filter cartridge plugged up and decreased the water flow it shut down, great reminder to change cartridges...

You set the desire pressure you want. When it reaches that pressure it shuts of. It also had an on/ off button if you change your mind. It is analog.

Yes, The on-off switch is as depicted in the image. I do not use this switch because I have a remote in-line switch in my hook-up but I would have no problem with using the pump-mounted switch. And, yes, as another reviewer stated, the pump does have a pressure switch.

You need to look at the various pumps offered. I guffed the first purchase and got one without a shutoff. I sold it to a friend and got another which specific addy showed a round bulb that is tethered to the pump and floats according to the water level it will turn on or off. The picture will tell all. This app read NOT to have a shutoff.

Yes, it shuts off automatically, and what ever amount of water you put in will come out. As long as you don't overfill the well.

We run it with the bucket, not a drain hose, so when the bucket is full it shuts off. I've not noticed it off otherwise. It's humid here, so we fill a bucket every day. Sometimes twice a day. Sorry, this probably doesn't help you with the question you want answered.

No. The water shuts off when there is enough in the tank. It only refills when needed.

if it's working right, it should pressurize it less than a minute. I've had major issues with two of these pumps losing the ability to come to pressure. Haven't had much satisfaction with repair or customer service. I would advise against this pump if you haven't already purchased one.

It turns on automatically when it senses water & shuts off when the water is down to an inch or less. This was the only pump we found in this price range w/ the automatic start/stop feature. I use it for draining excess water in my pool & it has worked well.

The pump does shut off so it does have a pressure sensitive switch. I don't know what PSI it reaches when it shuts off. Great, reliable pump.

This pump has an automatic pressure shutoff. I think it would work fine for your purpose.

I do not think so. I know when I turn it back on the pump needs to be restarted.
