That is a very involved question - offhand, I am curious how the pump could be 'too high pressure' for smaller k factor sprinklers. Most sprinklers have similar maximum operating pressures - k factor does not usually play a role there.
There are so many variables here, it could be that your designer just did not communicate them all to you. I think your best bet here is to iron it out with your design guy until you are satisfied and comfortable, or hire a 3rd party to review his work. If you are going to spend this much money on a system that will protect all of your stored goods, I would recommend paying a consultant who can carefully review all the details. The sprinkler forum is great - but you have a lot on the line to ride it all on free advice from an email chat. Good luck with your project!

No one has come forward with what I requested as of yet. My need is specific as I am purchasing a used diesel split case pump that is 2000 gallons per minute and my sprinkler design guy claims the pump is too high pressure for ESFR sprinklers heads that have a k factor of 16.8 or less. So I have to use upgraded high pressure fittings as well as Upright heads that have a high Kfactor. This is for high pile warehouse storage 30,000 sqft 20 foot stred racks. Any help here?

They are CMDA / CMSA standard response.

To my knowledge, the K17 Tyco TY7126 is the biggest upright ESFR unless you go Extended Coverage K25: TY9128 and Viking VK595. If you can go standard response (CMSA) then there are more choices. K17: TY7153, TY7151, VK580 and Reliable RA1124. Then K25 VK598 and Victaulic V4603.

I am looking for an expert in ESFR sprinkler heads to help me find a ESFR upright head with at least a K factor 17(not 16.8). There does not seem to be other companies that make these ESFR other Tyco. Please let me know. Thanks. Jeffrey Polke Co-President jpo...@gcioutdoor.com<mailto:jpo...@gcioutdoor.com>
