Dumb question about forging press

Mine is ALOT louder than I expected I'm running a 5hp 3250 220v motor and a 2 stage 2500psi pump. you can hear it here

Eric, your press is imPRESSive. "A bit" on a noisy side though, Jason's is simply LOUD. Thanks for sharing.
I'll try to show my project progress. Different frame layout, a bit different set of components and different "squeeeeshing target".

Actually if I will find the way to mantain the noise within an acceptable level that would be a good info for all of us. I'll write in this thread or in separate one about my findings.

I understand the benefits of the press. Just don't want to make them drawbacks instead of the benefits because of my poor engineering.
That's why I am willing to put few extra buck in bigger cylinder, pump and motor.
Actually I would go for a 22-25GPM pump and a 10HP motor, but I am limited in 220 single phase. 3-phase converter would break my financial back.
So I reduced my apetites to 16GPM and 5HP single phase set.

What I dug about the noise so far.
The pump emits the sound when it vibrates. It moves against the motor shaft because the joint has some play. So one way to reduce the vibration and the noise is to connect the shafts directly with no dampener. This will introduce a lot of stress on the motor rotor, but it will mechanially load the pump shaft and make it move smoother.Another MUST DO is to put motor-pump assembly on a SEPARATE HEAVY SOLID foundation. Than you can put this foundation on a layer of "soft" material. Like rubber or so.
I got this form the compressor guy. He said that a cast concrete foundation will reduce the noise twice as much at least.
I know many put their motors and pumps on the press legs. Or on the oil tank. This will AMPLIFY the noise. The "power station" must be separate and mounted on the solid heavy base. Cast iron base would be the best, but it is hardly doable in our cases.

This will also load the pump, causing end load on the pumps thrust plates, prematurely wearing out your pump and affecting the pressure your able to build. I would leave or get a replacement coupling sock ( maybe yours is really worn ) but I would not remove it ! Is your pump and motor connected by c-face, I would imagine so. Does it have the cover on ? That takes some noise away. Also if you have tube lines running from your pump to your cylinder and replace them with hose, that will take a lot of the vibrations (noise) out of it. As would adding Isolates to the motor feet. Hope this helps.
 
Jason, I clicked on that video and my cat leapt up and ran from the room! That is loud! I would check out the reasons for that much noise.
Dmitry, I used a Lovejoy coupler on mine, as that makes up for minor misalignment. I don't think that type of coupler could add any noise, as the spider is somewhat resilient and should dampen noise/vibration.
Have fun.

mine make's noise, but it's not that loud and it's a lot quiter than my power hammer.

My anvil is set in a steel tube filled with concrete and is fairly quite, no major ringing. My primary shaping avil has the horn cut off and is basicly a hardened rectangular block and makes very little noise.

I'd definatly sugest insulating and putting up OSB or drywall, helps sound proff and makes it easier to handle hot and cold weather.
