Hydraulic Pump To Power Triplex High Pressure Water Pump?

How big the hydraulic motor needed to drive the pump depend on the water pressure you require .

Pump power HP= GPM * PSI / 1714.

If you require pressure 10,000 psi

If you assume your pump efficiency is 80% ,

Hydraulic motor power required= 10*10,000/1714/0.8 = 72.9 HP

Thanks Bravo88,

The water pressure would be 13,200 psi. HP = GPM x PSI / 1543

This equation would give me: 85.5 HP

Your equation: 96.2 HP With this being said is 130HP engine suitable for this application, after adding up the additional equipment on this skid? Can you point me into the direction of the pump size needing to mount onto engine to run all this equipment?

Much Thanks again, Michael

The hydraulic pump size should be: power required/ efficiency

Thanks Tornado, But the reason we are wanting to use the hydraulic method is because of the engine. We have one engine needing to run three different systems on one project. The 6HP pump will need to be bi-directional, pto is pretty much one direction. "This Line" we are already is use with these setups, but unfortunately they would not be feasible for this application.

There is an IMT air compressor also being installed on this unit.

Thanks Again

what you are trying to do is the same way they have been running sewer /pipe jetting trucks for years.... for the Triplex pump why not run it shaft driven from the motor... will work a lot better and then a smaller hyd pump to run the vane pump. you will need a eaton/charlynn geroller type drive for that and in that HP type rating it will not be nearly as big as what you would need to drive the triplex I built one for a company that when I got done refurb'ing the vane pump I had enough suction to pickup whole cinder blocks from the bottom of 30ft deep manholes a bring them up w/o dropping.... for some reason after that my wife wouldn't apply the same principles to the central vac at home.... if you can find an old small dump truck trans with a pto setup that will fit your motor you will be off to the races. good luck bjd

Hello Michael,

I am happy to do the calculations for you. I need the following information.

1 What speed will the hydraulic pumps run at off of the engine?

2 Where off the engine Crankshaft or Cam shaft(camshaft is usually 1/2 cranks speed?

3 Duty cycle, continuous, hours per day etc?

4 What speed does the 6hp water pump require?

5 What is the distance between the engine and the water pumps. Distance between the engine and the control shack?

Regards

PS Any particular make of hydraulic equipment you would prefer?

Thanks So much!

1. Max. RPM of Engine is 2200, the engine will mostly run about 1300- 1500 rpm

2. Pump would be mounted to flywheel (crank)

3. Engine would run approx. 8 hours a day, BUT each unit would be interment, and would probably go active about 300 - 450 times a day

4. Anywhere from 250 -750max. rpm @ max HP 2.4 ( I don't see it getting above 500) (not sure where I got 6HP from, Sorry)

5. Engine would be approx. 15 feet from shack, and all units needing hyd. power would be within that distance.

I'm not particular.

Thanks so much, again. Michael

Hi Michael,

I apologize for not being able to reply sooner, I have tried three times and each time when I put in formulea the system crashes. If you still need my input this response gives CR4 permission to pass on my E may address to you. If you then E mail me direct i will do a response direct to you.

Regards

Oliver
