Hydraulic pump

All I have ever had were regular dump pumps, but I have used Permco, Parker, and Muncie brand pumps. I can't tell any difference from one to the other. I think the Permco would be worth a try for the price difference.

 

I installed a Permco pump on my W900 5 years ago, i needed to run a 2 line system but needed the extra pressure if needed in a walking floor, its actually a 3 line wetline but only has 2 lines with the extra pressure coming from a air actuated button on the control in the cab.
I think its called a Genesis, which has a adjustment for whatever pressure you need, i just installed a second on on my T 800 last year.
It also has a threaded location to install a hard line guage to see what pressure it is set at.
To get the best results from this pump i went with a 1.47% PTO.
With the different ratio on the PTO and the Genesis pump my 100 cubic yard walking floor can be unloaded in under 6 minutes running at 1100 rpm, most walking floor trailers take 12-13 minutes at 1200 rpm.
I will look at my paper work from the last installation to see what type of pump it is in my trucks.
With this installation you need a dual filtration system and certain size hoses.

 

I bought a Permco dual purpose pump years ago. I haven't had any problems. I use it on the dump side only and it unloads a floor just fine. But then again I run the truck at 700-800 rpms. to get 11-12 strokes per minute which the manufacturer calls for.

 

I tried using a regular 2 line pump that was on my Mack and had the same issues with heavy or wet loads, had to shovel off 10-15 yards to get it to walk, time consuming which cost me because i was paid per load.
That's why i went with the genesis, hauling 6-8 loads of mulch per day with no issues unloading plus i would get a extra load or two over other trucks hauling from the same recycling center, at @ $200 to $300 per load it adds up in the 3 month mulch season.
Plus Landscape supply yards wanted me to do there deliveries over other trucks because i didn't clog up the bins unloading, the 6-7 minutes less means more customers purchasing the product, not sitting there waiting for a truck to unload.
One of the landscape yards would get 25-30 loads of mulch per day, plus stone, fill, topsoil and hardscape deliveries, time is money.

 

Not sure what Permco pump you have on your truck or how old it is, when i set up my first truck through a Permco dealer they called Permco when i was purchasing a package set up and stated the pump rpm perimeters were 800 to 1200 rpm with the 1.47 ratio PTO.

 

Yes Sir. Loaded end dump with super slide. with fresh compost. most stuck to sides.lots of shovel. no more of that.

 

That always happened to me hauling chips and root in the winter, they would freeze and wouldn't come out.
