Kx033 pump upgrade options

[drc625]

Hey guys long time watcher first time poster on OTT.

I'm curious as to if it's possible to increase my aux flow a bit more to get better performance out of brushcutters/mulchers when using them. What would it intel to get to approximately 18gpm (if possible) on aux flow rate?

TIA

curious... looked online, current pump is good for 10 GPM....
The original pump is $9,000 CDN and unlikely a 'higher flow' version is available ??

One way would be to add a separate pump/reservoir/control/plumbing for JUST the 'AUX' connectors. Run the pump from the 'front' of the engine, you'll need to fit a 30 gallon reservoir, oil cooler.
Could be a 'challenge' mounting stuff, running hoses, etc. but it could be 'bodged'.

Yeah, I'm already wearing a 'flak jacket'..

Buying a bigger EX.
Not only is the pump an issue with increasing flow, but the size of piping and the HP of the motor.

buying a bigger ex isnt in the budget currently hence why im exploring these options

Ok let me put it in simple terms, no it's not a viable option!

It depends on the size of his wallet.....
For about $3,000 he can buy pump,tank, hoses, valve, bucket of fittings and make a TOTALLY SEPARATE system for JUST the 'AUX' function.
.... and how good a 'backyard bodger' he is.The only real challenge is mounting stuff, routing hoses, etc.

Guys add lights to tractors all the time, powered direct from battery so adding higher GPM 'AUX' to a digger isn't any different. Design it properly, install it correctly, good to go.

how would you even go about doing that? running the pump off the battery?
and this isnt completely off the table for me as im well versed in auto cad software and could design/make brackets to mount anywhere

Several things are against him.
He has limited HP to work with, and it's at the limit already.
He has limited space, that motor and pump is stuffed in there.

Hydraulic systems are designed from the ground up, size of pump, HP required to run that pump, size of lines, size of tank, and size of cooling are all carefully balanced.
Add or change one detail, like a larger pump and you will upset the system.

No you can not run a hydraulic pump off of a battery and get any kind of flow or pressure.

I don't think there is enough room to even consider adding a second pump to the engine.
Besides that you don't have enough HP, you've only got 23.3 to work with.

Sure you could pull the motor and pump and put a larger engine and larger pump in it.
That's not going to be cheap or easy, and there is still no guarantee it will work.

I guess you could strap a generator on the back and run a second electric powered pump to add gpm, you'll need to add more fluid capacity and you will need to add more cooling.
It's going to be a Frankenstein EX.

You would be far better off using implements that already match the flow rate that you have available.

re: running the pump off the battery?

Sorry, didn't mean to imply you could run the AUX pump off the battery just that guys modify their machines. Heck some put turbos on their little Kubotas !

One 'Rule of thumb' is 1 HP for every GPM@1500PSI, so you'll need about 20 HP of new 'engine' to power the new AUX system. As NIW points out it's more of a 'space' problem, can you PHYSICALLY fit everything in,on the machine, the hydraulics portion of the project is the easy part !

For 'fun', grab several cardboard boxes to stand in for pump, tank,engine and see IF it's physically possible to arrange them on the machine, just remember you have to service them !. Maybe use Google to see about 'gas powered hydraulic plants'. I've used electric ones in the past to test equipment. They're 'all-in-one' units, motor,pump,tank,control valve.

'hydraulic power unit HPU' is the term to look for...
randomly found this one

CP35 BVXL Briggs-Vanguard Gas Engine Hydraulic Power Unit, 0-17 GPM

CP35 Diamond Products Core Power Hydraulic Power Unit has a 35 HP Briggs-Vanguard gas engine with a maximum 17 GPM fully adjustable flow control

there are 1,000s out there so google a bit, to get an idea about cost and size. While diesel powered is probably more $$ ?, no chance of 'oopsy' when refilling !!!
