It is rated at 2.8 gpm at 3200 psi, however looking the pump's (4DNX25GSI) specification it is only rated at 2.5 gpm at 2850 psi. Is that normal?

I don't know if that's normal or not. All I can tell you is the owner's manual states 2.8 gpm @ 3200 psi, and it requires a 5 gpm @ 20 psi supply.

Advertised to do 1250-1450 GPH- but that will depend on the depth from which you pump. It is a good pump and buy estimation, I think you can calculate it will pump at least a 1000 GPH from a depth of 10 feet on a continous basis if it is a new pump and a steady electrical flow of 110 V. The weight is due to cast iron. In years past when it was made in Wayne, Ohio and not China, I think it was made of aluminum and very easy to handle.

At 40 psi and a 10' head (typical for a sump pump), this unit will move about 560 gph. The smallest Basepump (RB 750) will move 750 gph of sump water at the same pressure. I initially looked at this unit, but went with the Basepump HB 1000 instead as it will move 1000 gph and is of a higher quality. Additionally, the reviews for the Liberty frequently mention problems with the float valve. The float system on the Basepump does not have the same issues and is extremely well made. Also, it is not operating against the full flow of motive water; it simply acts as a pilot system to actuate a much more reliable type of main valve.

The one I received was the 800 GPM non-automatic bilge pump. It operates with a separate float switch. I use it in the shower sump.

The pump that came with my kit says "254 GPH". The pump is good quality and has four outlets and a dial to adjust air output. This pump easily drives all four of the airstones in my system, delivering a nice shower of tiny air bubbles. I suspect the output is high enough to drive two more airstones (six total).

The box says 1/2 HP 4200 GPH, but the chart on another side of the box indicates about 3800 GPH at 5' discharge height, and it goes down from there as the heights go up. I'm sure the answer is it depends on the diameter and length of the output line, as well as height, and many other things. At a 20' discharge height it's only rated at about 600 GPH.

2.2GPM , but flow rate has more to do with how many GPM you can supply than PSI . For example- if you have 1/2" water lines you will have higher PSI than 3/4" lines , but you will have more GPM with the 3/4" lines.

I agree it has to be lower than 40 psi. Probably between 20 and 30 PSA it is designed to protect the pump if the water supply dries up.

The pump is designed for maximum output with an engine of 13 hp. This hooks right up to a honda GX390 which is what i am using in my application. I bought and used my pump this summer and it seems to work well. no complaints.

There is no indication of the maximum psi in the owners manual. If it is any indication, the dial on the pump goes up to 150 psi (with the last 8 psi in a red zone). I personally have used it up to 50 psi with no problem.

I don't have first hand experience with this combination, but I think 2 to 4 psi would be the proper range. Factory Model As did not have a fuel pump, just gravity feed, right?

Not sure the flow rate specs but it works fine when running on my low pump setting.

Al, I am not home to measure this pattern, but I also mounted this pump on a Honda Generac and it bolted right up. If I remember right the holes are a little bigger than the bolt shank allowing for a bit of flexibility. 2.5 GPM

3.3 GPM, but only at 35 PSI. That's a very low pressure and I would not consider it for use in my RV. The Shure-Flo Revolution pump will provide 3.0 GPM at 55 PSI and the Seaflo pump will provide 5.5 GPM at 60 PSI, for instance, and both are cheaper.I can tell a big difference in my RV when I run from the internal pump at 55 PSI vs. when I use a "city water" connection run through a 45 PSI regulator (the internal pump outperforms the city water connection). The extra pressure makes a big difference, especially in the shower.

It depends on your injector size. I'm using 36# injectors and a Walbro 255lph pump. PSI should be 43lbs at idle.

1.1 gpm, max. 40 psi. More details in:http://www.directindustry.com/prod/flojet/container-pumps-14327-1155603.html

Please look under: "Product Description". It states: 97GPM.I have this pump for several months and it is great. I have a pool of ~12,000G. I run the pump 4 times per day 1hr and 15 min per run. Did not notice any change on my electric bill. The water is clear (I Ozonate the pool when pump runs) and I use one 3" chlorine tablet per week.
