On a 6cyl motor every cc is worth about 2hp if you effeciently burn it, less than that if its not an effecient burn and just ends up as waste heat. Is that 2500 pump/stand rpm or 2500 engine rpm(1250stand)?

[ford69557ci]

sorry bout that that is 1250 stand. tommorrow i am goin to run around and see if i can find somethin out on this seal if it is somethin that can be made work i think it will work great.

okay mr ford, what do you want to cram 70 psi into the vane pump all that is doing is feeding the case pressure if im remembering corecly, so what is your case pressure, and how are you ramming 70psi into wita a1000, or how do you do it, and how did you port the stuff out

[ford69557ci]

because a vane pump will multiply the pressure it recieves to a certain extent it will multiply the pressure but anything over 75 80 psi the vane pump dismantles itself. i am runni the a1000 on my truck now and the test pump is an aeromotive pro series its a few steps up from the 1000. alot of the porting was done with a dremel and way to much time. was it worth anything??dont know but i do imagine the larger inlet i fabbed up has somethin to do with it.

[cummins king]

i understand that it multiplys, your ramming so much fuel and pressure in the main stock feed that its just ramming it all long, i woder what your case pressure is

[cummins king]

why cant you and more fins to the thing that spins in the front of the pump sorry i forgot the name,

[seeker1056]

stupid question, but with all the machine work goin on why not groove the housing and the shaft for an O - ring or if there is room two spaced O-rings

If memory serves from other engineered pressure systems I have researched over the years, there are some purdy neat O-rings out there today that withstand a lot of heat and pressure

Heck even a seal for a hydraulic cylinder would probably work

I would bet the small groove required would not affect either the housing or the shaft

[cummins king]

seeker i belive you would still have to make a retaner from poping the o ring out the pump spins at half of the motors speed i dont think you would want an oring in there, thats why they used a seal

i dont think windnig the fins on the vain pump will work i think adding a few more fins would thou, one would have to makes sure that is pefectly balanced, because the vane pump works off of sintrifical force

[ford69557ci]

if you ad more vanes to the pump it ill reduce the area in the pump for the fuel to flow. o rings dont like spinning thing thats why they are not used on stuff other than stationary seals or things that move in a stroke type motion. i have a national seal book and a thermoking book so i will hopefully be able to find duoble seal to fit my pump

[seeker1056]

then how about moving the seal inward and cutting a groove for a snap ring to retain the seal?

[ford69557ci]

thats is possible but i still dont know if the single lip seal can take the pressure??? that is a very good idea though

[bgilbert]

Are you using Loctite on the seal? Knock on wood, mine is still holding all the a1000 will put out.

[ford69557ci]

yes it is locke tited and i took a chisel and staked it in but at really high inlet it either pushes it past the stake marks or starts leakin around the shaft thats why i am tryin to find a double lip seal

[PToombs]

If the seal has a rubber housing, no sealant, glue, or whatever, will work. If you get a good quality double lip seal that will stand up to the fuel and pressure itself, a snap ring would be the hot ticket. Most hydraulic pumps and motors have a snap ring holding the seal in.

[ford69557ci]

i got the guys at thermoking and mhc carrier workin on the double lip seal. alot of the reefer compressors and bus ac compressors run seals like that so hopefully they will find somethin. i am goin to pop my seal out tommorrow and see how much room i have to move the seal back and install a snap ring
