Yes the rings are provided with the circulator. Steve
The flange O rings were always with the Taco pumps that I have got from Pex Supply.

The pump comes with two O-rings. Jon
All circulator pumps have a maximum flow rate depending on the resistance in the pipes, or "head pressure." The higher the head pressure, the lower the possible flow. As you can see on the pump curve chart at the link below, the circulator will no longer be able to provide flow once head pressure reaches 9 feet. It can move 16 gallons per minute at 6 feet of head. Head pressure has very little to do with the height of the piping in the system. http://s3.pexsupply.com/manuals/1249544537780/101-085.pdf
My head range is over 32 feet, circle the hot water To supply water air handlers and sinks and Showers. No problem with pressure. Sent from my iPhone
Well, it depends on whether it is an open system or closed system. The previous answer is correct for a closed system which this pump is used. If you have a 4 story house will this pump move water to the top floor (32')? Yes, as long as the resistance in feet of head in the pipes, fittings, etc. are within the pump curve. The greater the Head the less the flow. Determine flow first then figure your pressure loss (resistance to flow, measured in Feet of Head) of your circuit from the output to the input of the pump, then choose your pump that will satisfy your flow based on the calculated Head loss. Water pumping up to 32' is balanced by water falling down from 32' in a closed system. The pump curve is based on water at 60 degrees, a specific gravity of 1. Anti-freeze decreases the pump's efficiency.
"Feet of Head" is a difficult term for some to understand. It is just a measurement, just as yards, miles/gals. and P.S.I. are measurements. 9.3 feet of head is the same as saying 4 P.S.I. At sea level 1 psi will raise water in a column 28". 28" divided by 12"= 2.33 feet of head. 1psi = 2.33'/hd. '/hd is just a finer measurement than psi. Pipes and fittings have a resistance to flow, called "pressure loss" "friction loss" "head loss", etc. This is the loss due to friction in psi or '/head in pushing water thru a pipe and fittings. This is the loss that the pump must over come before it can pump any water thru the pipe. Gallons of water per minute (flow) is related to pressure. It takes more pressure to pump 10 gpm thru a 3/4" pipe than 1 gpm. This is why you need to know (flow desired) and (friction loss in the sys. piping) to pick the right pump. Multi-speed pumps give you more choices in getting it correct. Gpm and '/Hd needed should fall in the middle 1/3 of the pump curve.
