Hydratight torquing and tensioning pump

Hydratight torquing and tensioning pump

We are looking to buy a compressor.


It is for a training centre workshop with classrooms adjacent and an admin office and staff room above so it needs to very quiet but powerful enough to do the job required.

It is to be used for mechanical joint integrity courses and the compressed air will be powering Hydratight hydraulic torquing/tensioning pumps.

The details for compressed air are:

The minimum is 72 PSI(5 BAR ) AT1700IPM(374GPM) for the hydraulic pump and for the tensioning pump 28CFM OF FREE AIR AT 100PSI.

I was going to use 8 mm compressed hose approx. 15 metres to initially connect between the compressor and hydraulic tensioning/torquing pumps.

I would like to get over what i need rather than under and i understand the bigger the tank the less it is in use,less making a noise?

Could you suggest a compressor or size that may suit?

Many thanks,

Colin

A tip - air to hydratight torquing
by: Doug in s.d.ca.

You'll notice that many of the compressors Bill pointed to have multiple pumps as the flow increases.

You can easily set up multiple compressors of similar or even dissimilar compressors to get a given air flow, as well as backup in case of a failure, by connecting two or more in parallel to a manifold, from which you draw the air.

If you decide to go that route, here's a "fer instance" of how it's done:

And there's more there, too.

Happy hunting, and let us know what you decide, would you?

Thanks.

Air for Hydratight torquing and tensioning pump
by: Bill

Colin, I took the liberty of adding an image of the Hydratight torquing and tensioning pump as some folks, certainly me, aren't familiar with them.

When you say "The minimum is 72 PSI(5 BAR ) AT1700IPM(374GPM) for the hydraulic pump", the 72 PSI (5 Bar) is easy to find, but I'm not able to convert the AT1700IPM(374GPM)to CFM of compressed air, which is what is needed to help identify the compressor size.

And for the "tensioning pump 28CFM OF FREE AIR AT 100PSI", I need to clarify whether the designated "free air" is intake to the compressor, for flow of compressed air at the 72 PSI.

In terms of quiet, either the compressor can be completely shrouded, with a filtered intake port to get ambient air into the housing to feed the intake on the compressor, or you acquire a very quiet air compressor, of which there are many makes. These can be run in an office with no real sound effect bothering those in close proximity, let alone a floor above.

Some manufacturers of quiet compressors for the UK market are:

Bambi
Clarke
Jun-Air
Sil-Air

... all of whom have silent or quiet compressors, and websites through which they can be contacted.

Smaller air compressors can typically generate 2-4 CFM of compressed air at 90 PSI for each HP of electric motor size.
