Air starting fire pump diesel engine

Air starting fire pump diesel engine

Air starting fire pump diesel engine

(OP)
I am trying to locate a high pressure air compressor driven by the fire pump engine (approx. 2500 psi), able to compress the air in several G-cylinders, to be used for air start of this NFPA 20 diesel engine (100 kW) fire pump. I imagine the delivery volume shouldn't be high, to minimize the size of compressor. Is there at all such thing?
Cheers,

RE: Air starting fire pump diesel engine

(OP)
Thanks cdafd,
The link is really interesting.
However, I was rather thinking on the line of a simple/standard air starting motor installed on this diesel engine (in lieu of electric motor starter), using compressed air from an air receiver. The NFPA 20 cranking requirement are so high, that a normal air receiver for this duty would be the size of a large submarine. However, compressing the air to 2500 - 3000 psi, the required air can be squeezed in 5-6 off 'G size' cylinders (like autogen welders cylinders).
The NFPA 20 recommends the diesel engine to be fitted with a compressor, to replenish independently of other air sources, the supply of air in the high pressure air cylinders. So I am looking for a high pressure compressor installed as an auxiliary compressor on the Fire Water Pump's Diesel Engine. I was so far unable to locate a such compressor, particularly of this high pressure output. It might not even exist. My last hope is that someone has heard of it or knows someone who might have heard something...

RE: Air starting fire pump diesel engine

call some of the big diesel engine makers??

RE: Air starting fire pump diesel engine

Thanks again, but (surprisingly) it seems that I was asking those big manufacturers (CAT, Cummins, etc.), way beyond the limits of normal applications they know of. Perhaps I was unlucky to talk to sales people only.
I'll keep trying for a while...

RE: Air starting fire pump diesel engine

Dear gr2vessels,Hello/ Good Morning,
I just happen to recall that we had with our previous employer's terminal probably three pumps having  air pressure driven turbo rotary starters with throttles&

two pump engine sets were having an air cylinder each to provide Min. 2-3 air volumes at desired normal kick-off pressure(s)

These were installed on 1) Fire water diesel driven pump,2)crude oil diesel driven pump and 3)Fuel oil diesel driven pumps.

These engine drive were most probably Caterpillar engines and we had a separate compressor to intermittently compress and hold air in main vertical air storage vessel along with piping to the individual pump set cylinders.

the compressor was in closest vicinity of fire water diesel driven pump with direct starting arrangements from main air storage vessel only for Firewater pump's engine.

Hope this off-hand recall from memory proves useful& helping for in some way!Feel free to discuss whatever I can put forward as a weak person.

Best Regards
Qalander(Chem)
