Listening to a book right now, and I have read this a few times before..

Boat in trouble, taking on water, Coast Guard helicopter lowers a pump to the boat in trouble..

How are these pumps powered, why don't all big boats in AK have these types of emergency pumps? Are they really powerful, and too expensive, so much as not to be affordable?
How are they powered that such a captain would be able to put it to use in rough seas? Self powered or plug into boat electrical?

Gasoline, older ones were the P100 and P250 but they I think they are using a P5 or P6. I think they were something like $6k a piece.

Ah, thanks.

The idea is additional pumps, if your onboard cant keep up or is disabled.
A gas powered 6inch trash pump, can drain a pool in less than 5 minutes

Same for drying a stripped pit in the mud, when your trying to keep the water off the pay, and your tractors unstuck.

I'd have to see that to believe that.

They can do 200-250 gpm, going off memory.

On my the vessels I was on in the early 70’s they were called P-140 drop pumps, gas engines .They were stored in a aluminum half drum with suction,discharge hose and1 gallon of gas.I started and ran them each month.

The book I'm reading right now is about a storm on George's Bank I believe back in 1980, NOAA screwed up their forecast. Pretty good book so far.
Good tribute to the Coasties, anyone who flies a helo in that type of wind, is not feint of heart.

LOL!!@ I re-read my post, I do sound sorta stupid
Indeed, to be clear; I aint talking about some air droppable/ portable 6" trash pump, Im talking hooked up to at least a 350 Chevy, if not something bigger and diesel power'd on a skid that we drug from pits and ponds to the next ones.

They were at least 2,600 gallons per minute with a 140 + foot vertical lift.

I'd bet they make a 6 inch Bilge pump, but I bet they do for bigger ships.What they move per-minute would depend on how much power they give it.

Only because my folks had a pool, had to drain it to acid the bottom once, hooked up to a gas powered trash pump, it took most of the day. Of course my recollection would put it at around 4" hose.

In the book the pump was put into a waterproof container, a line dropped across the deck of the boat, once the crew had the line secured, they dropped the pump into the water to be pulled aboard.

We had 1 P-500 and 1 P-250, that were both used as Fire and dewatering.
The P-500 was taking out off commission. As a fire pump the P-250 was 250 GPM when used with a Peri Jet educator for dewatering you could get 500 GPM..

Shuks........A 6 inch pump aint small at all.....a quick ''6 inch trash pump' Google search has this one at 1,200 GPM, 72,000 GPH, and that aint Chit compared to a bigger, higher power'd,higher torqued engine being chucked in place and let rip.


I'm not out to 'prove' anything, just spent a lot of summers in the muck, draining swamps (LOL!) ,making Gold and doing math.

I guess Im off topic Im off the sinking boat and up to my neck in mud.....LOL!

Yeah, most of my hands on experience were with P250's.

I’ve seen the coast guard and companies like Sea Tow use those pumps on boats taking on water in the Gulf of Mexico and it’s really pretty incredible , if you get those pumps going and start towing the boat they can save a sinking ship pretty quickly. Of course these aren’t 100ft+ boats like you’d find in Alaska.

Yes. Just finished a several year old book about a halibut boat that smacked a floating log. Captain and crew had essentially given up as the decks were awash. Coast guard put a pump on board, hooked up a tow, and saved both the ship and catch. Really if one does not have to do much lifting, he can move a lot of water in a hurry with a centrifugal pump.

Chip;,,,,,, Sorry, but a Pump with a 140 + foot of Vertical-Lift, is NOT Possible, not in this World anyway, see attached.

Chip,,,,,,, got to thinking about your Post, and did you mean 140 + Feet of Dis-Charge Hose/Pipe, as I took it "Originally" as Suction Lift, >?

I've seen a USCG jet fly out in the Gulf of Mexico and drop a pump to a small vessel that was in distress just south of us. They dropped it right in the middle of the deck. Probably a 30 or 40 foot boat.

Last I knew the CG was dropping and transferring the P6 pump. Simple Honda engine with an optimistic capacity of 250GPM. They are a good bit lighter and lighter duty than the P250.

When delivered by aircraft they are cased in a plastic cube container. When delivered by boat they are delivered in an aluminum cylinder container. A helo will lower a lead bag attached to a trail line. The crew on the distressed vessel gets control of the trail line then guides the container aboard. The pilots are blind to stuff directly beneath them. In addition to providing greater control and safety with the use of the trail line, the helo can kind of drift back so that the pilots can see. When dropped from planes they use parachutes with a long line. When they are lucky, they can drape the line right over the vessel. That doesn't happen often.

I wanted to add that the come packed with a flashlight and a quick instruction card. On the Gulf Coast the instruction cards are written in English, Spanish and Vietnamese. The connections are color coded.

Well, for the hell of it , I googled '' 6 inch trash pump, 140 foot vertical lift'' and this popped up.

Its interesting

http://www.equipmentsourceinc.com/equipment/pumps/6-trailer-mounted-pump

6 inches, 2600 GPM, 140 foot head...Ive got experience with this stuff.....Ive had this sort draining the pit, filling the wash plant tank and moving water up and out where I dont need it, and often the only way to go is 'up'
I apologize for getting OT.........

Ok Then,,,,,, 140 Foot Head, which is Dis-Charge, but when you said Vertical-Lift, thats "Suction",,,, Meanwhile back on the Ranch,,,

Hahahahahha......

When yer in the pit, the pump is down there with you, pushing water up to the 'head', however many feet that may be and thats what counts, if it cannot be sucked up there with a pump atop the pit.......and with the attached explanation, I understand, scientificly, why the pump aint up out of the pits, except my boss said ''Put it there!"' and that was the only explanation I ever got untill now ......LOL!!!

150 feet of hose is a heck of lot more managable than 150 feet of tubing.

We called it ''lift', for right or wrong, and just re-reading the specs on the pump I came across as an example, above, it too describes it as "lift". I assume the 'lift' isnt being sucked up, as the attachments explained that cannot be done..
Quote;
"The pump is driven by a turbocharged, four-cycle, variable speed Kubota diesel engine that provides a maximum shaft power of 70 hp. Together, the Pioneer pump and Kubota engine deliver a maximum flow rate of 2600 gallons per minute at 2200 rpm, with a vertical lift of up to 140 feet.
Rent an ESI 6-inch pump today for a pump-trailer set that will never shy away from hard work!"

Im sure its described by all of us differently, and theres nothing wrong with that.........

Hey Chip,,,,, well, we've pretty much rung the [bleep] out of this Thread,,,,,, and it's not to say that I haven't seen Manufactures Spec's Presented in an Incorrect manner,,,,,
ie..... Quality Control in the Sales & Editing Dept., with Brochure Adds Claiming Unattainable Spec's,,,,,
So just to be clear, this is "Nothing" against you,,,, but to set the record straight, the Pumps Head is Achieved by "Pushing/Pumping" the Water/Liquid/Fuel etc.... but First, the Pump has to "Lift/Suck" that desired Liquid up accordingly. So lets just call it,,,, "Semantics" I Guess.

Indubitably

And in most cases high winds

Not a coastguard man, but the emergency pumps I’ve seen are usually a Honda powepack driving a hydraulic pacer pump. Pacer pumps are an interference pump. They can move a lot of water in s hurry. Some fishing boats are rigged with a y-valve on the seacock of their wash down pump so the seacock can be closed and the suction can be put in the bilge to aid dewatering.

Right into the bilge?
