The unit I bought came with new rubber gaskets. Regards Eric Harless ***.****New Number) Sent from my iPhone
YES, This circulator comes with a set of donut gaskets in the box.
yes you do get the rubber gaskets
If the "rubbers" you ask about are the sealing gaskets, the answer is no. You purchase them separately. Don
Yes they come with the pump. Sent from my iPhone

The pump comes with two gaskets.
They normally come with the pump.
Q: I have a Wilo 16fx installed on my 100 gallon water heater and the loop services 24 apartments. The water is lukewarm at the end of the loop. The impeller is working fine and the water is130 degrees at the beginning of the loop. Is this pump to weak for the job? Does the impeller ever go bad? The part # is 4090767/0503

Verified Reply- PexSupply StaffIn all likelihood, this circulator is undersized for the application. The impeller can go bad, but it probably is not the problem unless the circulator had always worked well on this job in the past.
This question raises more questions than answers. *What are you trying to achieve with the pump? Are trying to circulate hot water so all apartments have instant hot water? *What is the distance of the system (total pipe length) that the water is traveling through *What is the diameter of the pipe? *Are the pipes insulated? If you are trying to end with hot water at the end of the cycle, you will probably have to flow a LOT more water. This is due to the heat loss through the pipes, time it takes for the water to travel through the system, etc. 24 units makes me think it is a rather long line. If they are not insulated, you may never be able to achieve what you want. This may not be what you are looking to do as 100 gallon water heater sounds very small for 24 units. If you are trying to supply hot water to the last unit in line, pump a lot more water through the system and/or insulate the pipes. The cost to heat the water will go up if you try to keep the pipe and water hot all the time. Don
well you are trying to do too much with too little, that is the problem, the tank isnt big enough to service that many apartments and that number of apartments in a loop is far beyond reasonable, the system will never work, at least nothing that i would be happy with, you need more tank capacity and yo need more loops rather than one, that is a serious mistake, in fact both issues are serious mistakes.
