Wet kit

For an end dump, you'll need about 2000 psi, and just a 2-line will work (one from the tank to the pump, the other from the pump to the trailer). Walking floors will need a return line from the trailer back to the tank (3-line)...not sure the pressure requirements.

Not sure what you mean by air slide. If you're talking about the 5th wheel, that really doesn't matter...same wet kits that work with a fixed plate will work with an air slide. If you're talking about the engagement and controls of the PTO and pump, most of them are air-powered.

 

Tandems. Some trailers use a valve syatem to release the tandem pin so you can slide the tandems. You see them a lot on reefer trailers.

 

You'll lose efficiency and generate a lot of heat using the wet kit to power a blower for a pneumatic. You'd be better off doing like I did...mount a PTO for the blower on the 8-bolt side, and a second PTO for the hydraulic pump on the 6-bolt side. Easy to do on a Mack transmission. If your 8-bolt is on the belly of the transmission (Eaton), you may have to run an idler gear between the transmission and hydraulic pump. That will reverse the rotation of the pump, so make sure you either buy one set up for that or make the necessary modifications to make it work. Other problem with running an idler gear is that it sets the weight of the pump farther from the transmission...so make sure you have enough support brackets and such or else you'll have leaks and stuff can/will break. One other option would be a remote-mount pump, similar to the blower. You'd mount the PTO on the transmission, the pump on a bracket off the frame, and run a drive shaft between them. That could solve both the weight issue and clearance issue...but you'd have another drive shaft to maintain and look after.

 

This is the best option if you want a wet kit and a blower. I currently have a 12" GD blower running off my 8 bolt PTO and if I ever need a wet kit I will install it on the 6 bolt side. Blowers take a lot of horsepower to run them.

 

Then run a dual pto.

 

If you don’t like long Pto driveshafts you can put a direct drive Hyd pump and a hydapack cooler into your blower....no shaft anywhere.

I’ve got 2 direct drive Hyd pumps on mine.... one on the bottom port with tankless cooler set to run a product pump.... and the other on the side port with a 65 gallon tank (no cooler) for a dump trailer....

 

I ran walking floor and it's only 2 line. The mechanism works from the oil flow, so it needs to return.

An end dump puts fluid in the ram. When the ram comes down, it goes right back through the same hose.

To run a walking floor, you hook up the hoses, and turn the pto on. The controls are on the trailer. To control a dump, you engage the pto, and then use a valve to control flow to the ram. You would need to add that control valve to the kit in order to run both.
