About 5000 hp, unless your units are a typo.

Pick up the phone and start talking to pump suppliers. There's no better way of learning than doing that.

US or Imperial GPM ?

Quite.

"US Dollars or Zimbabwe Dollars?"

GA :-)

It takes a lot more to specify a pump. Here are some of the things that pump vendors will need to understand before making offers:

• System temperature
• Reservoir capacity
• Intended operating time
• Method of drive
• size of inlet and outlet connections
• method of attachment to inlet and outlet connections
• wetted materials
• method of starting
• method of stopping, if any (some fire pumps are designed to run until the reservoir empties, until the fuel runs out, or until catastrophic self-destruction takes place, whichever happens first)
• intended location
• elevation relative to the top and bottom levels in the reservoir
• weight constraints
• leading dimension constraints (will it pass through that doorway or does one need to take the roof off to get it in?)
• handing of the equipment
• project timing (it is not worth a vendor's while to chase a contract for supply next week if other customers' orders mean that a six-month queue can be expected for new orders)
• The facility's spares stocking arrangements and standards (there's no point in installing a Bullshine Ltd. brand pump if all the others at the facility are manufactured by Codswallop Ltd. and their spares are already in stock)
• The facility's maintenance arrangements
• etc.

Good luck with those phone calls. Do let the forum know how they went, though please do not disclose the chosen supplier in subsequent postings as it may prejudice commercial arrangements with other suppliers.

Will your fire suppression plumbing be two inch or three inch diameter pipe?

Take another big hit of whatever you're smoking and us call back in the morning.

"hopeful for help thank you"

Hope springs eternal, so they say.

What is ksi is it psi? More details are needed to suggest the right answer. Better call or consult pump manufacturer and hey will get required details from you and offer you right pump for the application.

ksi=1,000 psi.

The absolutely first thing to do is to understand what you want and what you have to have to get it, reference #2.

Get, study and understand what the practical standards for sprinkler systems or whatever system you want need. Obtain your own copies of the following NFPA, National Fire Protection Association Standards (they are cheaper if you join the NFPA and purchase at least a year membership. Purchase a set of all the standards, available on CD or printed, since the cost of each of the 6 standards purchased individually will be more expensive than buying a whole set of all standards):

NFPA 13 Standard for the Installation of Sprinkler Systems

NFPA 14 Standard for the Installation of Standpipe and Hose Systems

NFPA 15 Standard for Water Spray Fixed Systems for Fire Protection

NFPA 20 Standard for the Installation of Stationary Pumps for Fire Protection

NFPA 22 Standard for Water Tanks for Private Fire Protection

NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems

Identify what all your needs are first, study the standards and figure out what it is you need. Better yet, hire a licensed professional Fire Sprinkler designer, and have a licensed installer make and install it.

Fire is extremely dangerous, IT KILLS!

Good Luck, Old Salt

Are you sure this is a a fire application?

A pressure of 4ksi which I think is 4000psig (276barg) would require 2500# rated piping. My experience is for fire water systems on refineries and gas plants and similar. For those we only use 150# rated piping with a typical 5 bar required at hoses / monitors deluge systems

Also 276 barg equates to 2800m (9200ft) of head so even for a really tall building this seems a very high head. Pumps can be made to deliver this head but the motor size is prohibitive as noted above and its a very specialised pump to get this head.

Please check your details.

The flow rate 1800 USGPM (assumed) 400 m3/hr seems like it would need 8" or 10" piping which seems quite normal
