Questions on an old hookah set up

[AKSasquatch]

Hi, I? new to the forum but have gleaned a ton of helpful information from old posts. I picked up some pretty vintage dredge gear the other week. A 3? Keene Dredge with a Copper 5hp Briggs and 14x48 crashbox sluice and a P-150 pump, which has air from an old compressor. I contacted Mark at Keene and he said seals were available for the pump WPS2 and P104 to replace the paper gaskets but no parts were available for the compressor.

Mark said it was an old Teledyne and a post on here referred to it as an Inlet model. It does seem to be making pressure just fine, any source for bearings or diaphragms? Do you think it is safe to use after sitting all these years? I would be in water I can stand up in if air failed. Debating whether to buy an air reserve tank and hose for it.

Went over the engine and she runs great, got her out and dredged for about 5 hrs without an issue besides a couple rock jams. Dredging bedrock is fun! Never know what deep pocket you will find. Had a blast. Thanks for any info!

If you were to have any problems with the compressor you could take it to a pump repair shop and they should have parts for it! On my dredge that i had for maybe 15 years ,I bought a compressor for it that looked similar to your compressor. I took it apart to check the diaphragm and it looked like it was a home made replacement . It worked fine for many years without any problem. The man I bought it from said he did the work on it and it worked for him but he said he wouldn't trust it in a deeper dive over his head. I never got that deep . I eventually sold all my equipment and gear due to my beat up ole body. and the air compressor parts could also be bought from a pump repair shop. Since your new to this underwater diving . You need to be very particular with your air line / mask / and anything in the air system . Always hang your suction lines to drain down and not laying flat on a floor or curled up. Never leave your dredge/ lines/air lines out in the sun for extended lengths. A reserve air tank is EZ to make from a stainless steel "corny keg" tank that is/was used in soda fountain's . They used to be found over on Ebay cheap ! Try to get the 2 tank connections that are used on them . Sometimes you can find a beverage repair man will have what you would need to get you going. IF you do use a "corny keg" in each of the inlet / outlet fitting's there is a Stainless steel tube that inserts into the tank. Take those tubes out to get more air! It'll make a big difference if you do! Also the "crash box " device on your dredge is great for dredging in clay ridden streams to help bust up that clay that sticks to everything. try to avoid sucking in clay because it'll rob your sluice of fine gold. And OH YEA , Happy 2nd post!

And if your air compressor don't have a pop off valve GET ONE ! It screws right into the head of the compressor and you attach the air lines to it! They are adjustable for your breathing air pressure ! And make cleaning your air system regularly a COMMITMENT ! I used Listerine mouthwash for my extended times I needed (Winter)to store it! Good luck and enjoy ! I wish I was still able to get out there !

I'm speculating but it seems to me the only danger to worry about besides lack of air pressure is an air supply that includes engine exhaust. Exhaust includes carbon monoxide and a build up can kill you. Keep your compressor air pickup upwind of the exhaust.

Good luck and welcome to the forum.

I have a couple of those Teledyne Sprague compressors, parts cannot be purchased. Pull the head off and check the reeds and the diaphragm if its all clean looking and the rubber isn't shot I'd run it and try. The intake on the top has threads under the felt filter, pry it out with a screw driver and thread in a barb for a air snorkel hose. These compressors put out more air than a T80. A reserve tank is absolutely necessary. I run a corny keg like Russau.

Foe me , I like using the Stainless Steel "Corny Keg" because of it's size and the material it is made of (Stainless Steel) it's very durable and can be opened up to be able to inspect and thoroughly Clean the inside of this Tank to keep the MOLD eliminated. I once saw a full coverage mask that had black mold covering the inside of it! They used it that way until I told them what that black stuff was ! If your not going to use the system for any time soon, clean it out with alcohol and put it awa Same with your air hose!!!!! And keep that felt filter clean !Mouth wash for me is a good thing to keep in your air lines while NOT using to keep the mold at bay!!

 

[N-Lionberger]

I went to the corny keg because I can open it up and clean it as well as have higher capacity. You only get one set of lungs make sure you know what you are putting in there.

 

[AKSasquatch]

Wow, awesome ! Thanks for all the information! That is great, I actually have one of those kegs sitting in my garage, perfect! Thanks for all the tips on the compressor and details, I was wondering how I might mount a snorkel for the intake, good to know there is something under the felt filter.

 

[russau]

To mount your snorkel all you need is some pvc pipe and a 90 degree elbow and some brackets for clamping it to where you want it to stay. I had a pvc coupling to my intake pipe to keep it low (height wise) while traveling or storing it. and I keep a zip lock baggie over it while NOT using it to keep dirt and bug's out of the system. Keep all openings of your system closed / sealed off while NOT in use.

Well the dredge got some gold and seemed to catch really flat fine gold pretty well. Not bad for a first attempt.

I think this is the type of keg you are referring to, just have to get the connections from a beverage supply shop. Looks like it will fit the dredge frame with a slight extension pretty nicely.

I took the top half of the compressor off and the diaphragm looked good to me, removed the four screws on the top half but nothing seemed to separate easily so didn?t want to force anything. Should I tear it down further? Also look like some sort of vent or fitting but not a typical pop-off valve so I will look for one of those as well.

As for the snorkel the inlet did not have threads under the felt but it may be a diameter that a simple pipe will fit if braced, any need for an air filter on the top of the snorkel?

Thanks for all the help!! Sorry, not sure why all the photos loaded sideways.

 

[AKSasquatch]

Is this the type of pressure relief valve I would need or would I get it from a dive shop?

Thanks.

That device is tooo expensive ! Any mining supply shop (Keene ,Action mining ,ETC. used to sell them for about $5.00 each BUT it's be awhile since I bought one. and yes that is the Corny keg to use. Try to get replacement "O" ring's for the access lid , spare's will come in real handy as time march's on and parts become harder to get. If the compressor doesn't have a "death rattle" while you ran it , I wouldn't tear it down further ! It appears you did real well for your first time dredging ! CONGRAT'S I still remember my first gold ! How sweet is was !

already has a pressure bled valve, buy a dial pressure gauge to set at around 40psi, its a spring and ball bearing type. (in your middle photo)
my Dad had that same air compressor in 1970, helped him put in a new diaphragm he cut out of stock rubber.
also works good for spear fishing, cheaper air hose I use is Kuri-Tec k3150 or K3130 food grade hose that's also rated for air breathing lines.

Although i have never used this line... i know "compression" type fittings should not be used with this.

Nice setup, like the combo snorkel/dive flag.

 

[N-Lionberger]

I hoseclamp a piece of felt over the end of my snorkel to keep organic matter out.

 

[Jager32]

I would replace compressor, and get air quality checked, use a reserve tank, and like what was mentioned above keep your air intake up wind of the exhaust and check periodically, and watch your hose doesn't get pinned or fouled. I was a commercial diver/supervisor for 43 years, don't go cheap, be safe and good hunting.

That'll work fine! BUT keep something over it to keep the dew / rain off of the felt when it's not in use or it will clog up quickly when wet!
