Three questions, really. The first is for a recommendation for a pump:
The intake is 10' below the pump house, and the rise to the cabin is 40' with about 100' of run. Additionally we are putting the water through a Pura UV20-3 filter system, and a flow regulator set at 5 gal/min.

2nd) It would be easier to put the Pura filter in the pumphouse, but will that kill the water pressure to the camp too much, compared to putting the filter in the camp?

3rd) And should the bladder tank be after the filter, or before the filter?

Thanks in advance.

How far down to water? That's the big question. Perhaps that's what you meant when you mentioned an intake 10' below the pumphouse. Are you referring to a lake???

I would not think it would make much difference where you put the filter. In the camphouse would certainly be much better for installation and maintenance. At their website, it did not state how much pressure the filter costs you. It is typically not much. The website seemed to think of their filter as being used for municipal water, which I thought was kind of strange. It did not mention a well, at least not that I saw.

3rd) And should the bladder tank be after the filter, or before the filter?

The filter specs will probably address this, but filters are typically installed after the pressure tank. Call the manufacturer and ask: PURAUV.com — Ultraviolet ( UV ) Water Filter & Filtration — The Pura UV20 Series of Small Whole House UV Units (http://www.purauv.com/purauv20.htm)

Yes, the lake water level is 10' below the pumphouse. The run is about 40'. The intake/check valve is below that of course. Thanks for clarifying that.

I will call the company and find out how much pressure the filter costs and their recommendation on the bladder tank location.

If you plan on putting the pump in the pumphouse, which would seem rather logical, then you are only 10' to water. A shallow well jetpump will do. Many people use Flotec, but some of the other guys on this site might have better suggestions.

As far as the filter goes, if it costs you 3# of pressure, as an example, then it won't make any difference where the pressure loss takes place. 3# lost is 3# lost. I really don't think location will make any difference, but that's another question you could pose to the manufacturer.

What about the hp? Would a 1/2 hp have enough pressure, or do I need a 3/4 or even a 1hp? I figure there is something close to 10psi lost raising the water from the pump house to the camp, plus the loses for the filter, and then loses for the bends. I would like a nice flow when it comes out of the shower. Right now it sort of dribbles. We currently have a 1/2hp, but it is an old pump and is probably not working to max efficiency. The bladder tank (at the pump-house) is set to 40psi, but I am not sure the pump could take more than that without strain.

You said the rise to the cabin is 40 feet. That will cost about 16 pounds of pressure.

The bladder tank should be set to 2# below the cut in pressure. So if your switch is set to cutin, for example, at 30#, then you'll set the tank to 28#. Do this with the power off and pressure drained to zero by opening a low level faucet.

You described this as a cabin, so I'm assuming this is a vacation/hunting situation. The size of your pump will depend on demand in gallons per minute. Figure about one gpm per fixture. A half horse pump pulling from 10 feet down should give you 6 to 8 gpm, which is probably going to be plenty. But you can check that on the pump's specs before you buy it. Assuming your current pump is 110 volts, just be sure that you buy a 110 volt pump.

The big danger I have found with this pump is the fact that the impeller housing is plastic, so don't overtighten the fitting when you connect to it. The plastic will split. Bummer.
