Wet kits for crude hauling.

It's a pump not a hydraulic lift pump. You don't need a reservoir because you don't fill a cylinder with Hydraulic oil.

 

I have used 2 gravel trucks and used them in the patch. On most oil haulers they will have something like a Gardner Denver hydra pak which holds a very small amount of hydraulic fluid but also has a fan and radiator to keep the fluid from overheating, whereas a gravel trucks hydraulic system (at least the ones I've bought) have a massive tank that keeps the fluid from overheating due to sheer volume.

A big difference is the pto. A pto from a gravel truck is a way faster one and would blow a oil pump into oblivion.

 

YUP! Need a PTO? I have one for dumps. Used about 6 mo on long haul for Oakley so only dumped 2-3 times/ wk.

 

The other difference to consider is that lots of crude and condensate haulers need a PTO to be reversible, so they can suck out the lines and avoid or reduce the possibility of spills. Most dump pump PTO setups don't have that capability.

 

If it's a wet kit the pto is one way. The hydraulic level controls direction. The 2 way pto is for units that run off direct drive. (Drive shaft driven)

Reversible PTO's, not drive shaft driven.

 

The chelsea pto which you have linked 2 is in one way or 2 way. The 2 way will have a thin driveline attached directly to the pto and the other end directly to your product pump with a steasy bearing in between, turn the pto one way and it loads...... the other way it unloads.

The one way pto has a gear on the end, a vane pump, piston pump or as many call it a hydraulic pump bolts onto the pto and the pto and vane gears mesh. The vane pumps are designed to go only one way. There is a low pressure inlet in which it sucks and a high pressure outlet line that blows the hydraulic fluid, if you had a 2 way pto attached and reversed it the low pressure side would blow thus hydraulics use 1 way pto. The fluid goes from the vane pump to the hydraulic 2 way lever and from there to a hydraulic motor that's hooked to the pump. Forward on the lever loads and backwards unloads...... that is what controls the direction.

It may be possible that maybe you could have a 2 way rigged up and pressure lines on both sides of the vane pump (if you find one meant to go both wayes, although the ones I've seen are either clockwise or counter) and you could then not have a hydraulic level (which of course usually contains your bypass and pressure relief valve so your hoses don't presource up and explode) and maybe it would do just fine without killing you, but I have not ever seen a setup like this and don't believe them to exist.

I sure as heck don't know near to everything so maybe I'm wrong and have no idea what I am talking about.
