Fire Fighting Pumping Unit

02/23/2012 1:13 AM

I need to build fixed skid mounted FFPU consisting of three pumps (namely electricity operating pump 500 GPM, 7 bar, diesel engine driven backup pump 500 GPM, 7 bar and a jockey pump 50 GPM, 8 bar) with water supplied from city source and stored in fire tank. All the pumps (centrifugal) should have common suction and discharge pipe.

I need:
a relationship of calculating diesel engine (rating) from known pump type and size
relationship(s) for selection of valves (types, ratings, characteristics (linear, equal percentage etc.) etc.)
relationship(s) of calculating piping (size, lengths etc.)
relationship(s) of calculating losses in piping and pump set and way to incorporate them into the final selection
relationship(s) of calculating sensor(s) and controllers (actuating time, operating voltage(s) etc.) from above data
relationship/circuit diagram of designing control unit (consisting of sensors, controllers etc.)

Mundus,

I may be wrong and stand to be corrected, but it appears you want CR4 to work out your entire package?

I'm curious to see if this happens, if so I would be surprised. Is it not a little better to work out a few of your "I need" topics then ask for help in verifying work that you have at least begun on your own?

Pump packages are offered from numerous manufactures skid mounted, electric and diesel driven to meet the demands you have mentioned. Once you begin working with the selected pump manufacturer, they may easily clarify 80% of the "I need" topics based on the pumps operating parameters. They will be willing to offer this data to ensure the pumps are installed to specification.

You get very good advise from this forum, but not often a complete project put together free of charge.

Tim

Before you build it, you need to consult a designer, Uncle.
