Question 1

is this an on demand pump?

Accepted Answer

Yes, this is "an on demand" pump.  It has an internal pressure switch that starts the pump when the output pressure decreases (such as opening a faucet or flushing the toilet.  It will continue to run as long as the output pressure is below 55 lbs.  Just remember that the pump will continue to run after the faucet is turned off until pressure in the water line reaches the 55 lb cutoff pressure.  Any leak in the line will cause it to cycle sporadically because the leak reduces the water pressure.  Also, if you have an accumulator in the line, it will take longer to turn off as it has to fill the accumulator reservoir to the cutoff pressure.  However, with an accumulator, it won't turn on as much either.  The hardest thing you can do to any motor is continually let it cycle.  Battery draw can be 5 times higher during startup as when running.  These are fairly high amperage devices (about 7 amps) and can shorten your battery time when dry camping.

Question 2

What is included with this pump?  Any accessories, fittings, etc?  Is it a straight replacement for a 2088-422-444 or is anything else required?

Accepted Answer

I ordered this product in September 2018. It came in a retail box with instructions and 2 fittings. I replaced a 2088-422-144.

Question 3

Hi. What's the max. liquid temperature that it handle? I need to transfer beer worth at about 90 °C...

Accepted Answer

This pump is rated for use with liquids up to 130F (54C) as stated below in the product details.  I searched the SHURflo website to find the info, then came back here to see the answer in front of my face.  Sigh  Well, aquaman, I make beer as well, and that's a great idea to transfer your wort with a 3 Gal/min pump!  I use a racking cane, basically a siphon tube, to transfer the wort, which can be a hassle.  Please search for model 8050-305-526 here on Amazon or on the SHURflo website to see a pump twice as expensive but is meant for pumping engine oil and transmission fluids in boats/RVs.  I couldn't find the heat liquid rating, but I think that will do the trick.  All the Best!

Question 4

Will this pump provide enough pressure for watering a remote garden?  I have a 275 gallon water tank and need pressure for the hose.

Accepted Answer

it will, but depends on how much watering youre going to be doing .. if you need to run a sprinkler for a couple of hours to cover a huge area you need a bigger pump, i dont think this should be looked at as a 'constant duty' pump ... for instance, if you have a little 8X8 area you want to soak down for a few minutes it should be fine ..
