want a wet system and dry bulk system on same truck

Why not a hydraulically ran blower? Then you can switch your wet kit to run it or whatever else just make sure you've got a good cooler for the oil.

 

check out hydra pac and S&S make a hydra pac unit both are very good and simple setup.

 

Just make sure the hydraulic system can produce enough torque to start the blower.

 

Why can't you run both off a single PTO pump? They make valves and parts that can achieve this.

 

You can, if both units require the same pressure and flow rate.

 

You need the correct PTO output speed for each application.

If not using a Hydro pac you need two PTOs, one set up for each.

Your blower needs to turn a lot faster than a product pump.

Adding a air compressor needs a third PTO and complicates things.

There are transmissions set up for left, right, and bottom mounted power take offs but with the DEF system and fuel tanks, running three might be a massive headache.

Also be aware that some mega trucks might have the interior gear that drives the PTO omitted from the transmission.

Any company buying a few hundred tractors has the ability to reduce costs by omitting 'un-needed' items and loose weight too.

I've seen guys run into the missing PTO gear as they went to transfer their old setup to another horse only to find they have to get the transmisson re-worked.

 

Easy enough to step down the flow/pressure to match the second system. Its done all the time on heavy equipment.

 

Drum hydro pack for the blower , and separate hydraulic pump for the dump trailer…. It’s the easiest way. And it won’t be cheap .

I always use D and W diesel in Albany NY

D&W Diesel

 

I don’t know a whole lot about it, but we used to have both wet lines & pto driven vac pumps on our trucks when i hauled haz waste. I could drag a tank wagon today and a dump or rolloff tomorrow.

Trucks were off the lot, nothing fancy.
