Questions & Answers

This set has bolts of different sizes. What are they?

They were 1/2" x 2" according to what I remember

How much power is this unit drawing at the moment, and what is its maximum temperature? I need to know what to do. Are you able to speak face-to-face with me?

Can you clarify what you mean by draw, are you talking about the amount of water that circulates in the system in amperage units or the rate at which the water circulates? My unit operates fine at 120 degrees F, but I cannot estimate what the maximum will be. If the manufacturer has the specifications, you can ask them.

Which dimensions do these flanges have? I was wondering how far apart the bolt holes are? Is the diameter of the short side larger than the diameter of the long ?

There are 3 1/8" holes from center to center in the bolts. There are two bolt holes that measure roughly half an inch in diameter. About 5/16" from the edge of the flange are the holes. Please accept my sincere thanks for your help. I'm Mike.

There are 1" input and output connections on my boiler. Could you tell me if there is a 1-inch ?

Here is what you need to see. The Grundfos 519602-1 number can be found here A cast iron flange set GF 15/26 in inch size with ASIN

Selected User Reviews For Grundfos 519601 Cast Iron Flange Set for UP Series Circulator Pumps-3/4 NPT, black

If you need these parts to supplement your system, they are of good quality

3/5

It was not certain whether I would require this item or not when I ordered it. It was not necessary for this item to work as it should because everything else worked on its own. I didn't need to order this with the pump and comfort valves to have everything worked as intended. Nothing wrong with the item, and I didn't need to order it this way. You can use long-lasting parts, if you need them as a replacement for your GRANDFOS Recirculation Pump and comfort valve.

This is something I have to have It's a must to have one of these sets if you want your pump to pump water

5/5

The pump does not have any connections Several years ago, someone discovered that it was a lot easier to replace the pump if you left the flanges in place, screwed into the piping, and then slid the new pump over them. As is typical of Grundfos, they are of industrial quality.

It would be nice if there were a U-shaped flange instead

4/5

Made in the U. S. The 3/4" coupling fits my Grundfos pump perfectly. Despite the fact that the pump comes with these flanges, I still cannot understand why they aren't included in the package. In addition, these flanges are made here in Taiwan and not in the U. S. It is imperative that our economy and people start paying attention to the trade issue to increase job growth and boost economic stability.
