ps pump does this just internally

you realize this pump thread has been going 10 years and previous ones are some years older than this...….
@ZAG So over time spinning the pumps at over double their rated rpm doesn't seem to have affected anything? Do they make any noise?

havent noticed any issues related to spinning them high rpm more noticeable is when pumps wear by time they loose low rpm power.

they just make normal gear pump noice.

alright, this seems like the thread to bump with this dudes stuff for folks looking to run the 'industrial style pumps'. I'm sure that there are others, please chime in with their information, but i was having difficulty when i was looking to the point that i was going to end up going with my own stuff.

The "kit" is pretty well setup. an adjustable flow compensating valve to effectively vent all excess flow, a mount of your choice for various spots on a stock LS, a pump support with a bearing in it to handle the side load and it can be set up for various displacements, as they are typically available with similar shafts

This is his image that would be ideal for mounting higher displacement pumps and/or long pump life. gear pumps are rather tolerant to high RPM, but at the end of the day, it is better to underdrive them



stock location, stock pulley (is my guess) so this is going to be a bit over-driven, smaller disp pump

I have no affiliation with the dude, just had a very short convo with him based on a random facebook post. seems like it would be a good fit for folks who don't have machine tool access but want to play around a bit more with various pumps

shit, i've been reading your threads for years, i know i'm easily a decade behind the times there is just. so. much. and it takes a bit to process I'll be good and stop bumping all your old steering tech pretty sure this is the 3rd one in a week

my thread is a long journey of self discovery, for everybody else, they may be better served just jumping to the end as i've got my plan pretty well formulated and the best two versions are both on the last page

I think it's cool how we can jointly invent shit like this as a group. It's why the internet was born, to share ideas and advance the culture. It's why it took a hundred thousand years to invent the wheel but then only a few thousand more to put a man on the moon. And now I can sit on the toilet with a computer the size of a credit card and watch Japanese chicks shit in cups and eat it. I mean, seriously, what exemplifies the achievements of man more than that? We truly live in great times.

Yes. There would have to be a relief valve somewhere to protect the system. Otherwise pressure would just build until something popped.

What is your entire system? A pressure relief valve may also be easily incorporated into another valve like a DCV.

Either in this thread or in the other "want to talk about hydraulics?" thread, because there are several options, post up what you are trying to run. i'd like to walk through your whole system, helps me learn stuff

the scotts custom off road kit doesn't have a pressure relief valve, he is selling it with a flow control valve.

in a way, the flow control is similar to a pressure relief valve, as it is providing a direct path to tank for excess flow to keep neutral pressure down.

In another way, it is absolutely not a relief valve, because the style pictured will divert to the priority flow line 100% in the event that the priority flow drops to 0. this is intentional so that the max system pressure will be available to whatever motor/valve that is hooked up to the priority flow side. so it shouldn't be relied on as a safety switch or fuse, like a pressure relief valve.

edit: for example, most every steering valve has an internal pressure relief, so that when the cylinder hits the end of it's stroke, the valve will relieve even if you keep spinning the wheel. otherwise, it would just try to build pressure until it blew out the orings

Just looking to run a hydro steering system. I've followed your thread and hence realized the need for some sort of relief.

I know they sell stand alone version but I also found that all of the manufacturers offer a integrated relief valve that attaches to the back housing of the pump and diverts excess fluid to the tank line.

Being the OCD I am I don't like adding on a valve if I can get it built in however I'm running into the issue of yes they are in a catalog but no one really sells them or has them in stock.

Since I'm only running hyrdo steering I was not leaning towards an flow diverter for as you mentioned above.

Scot''s setup does have a nice bearing and pulley which would save abit of work of figuring out, etc.

the flow diverter is what will give you consistent steering as well as reduced load.


edit: depending on the steering valve you run, it *should* have it's own relief so that it isn't trying to destroy the cylinder and will instead bypass internally. if that is the only valve in the system, it would offer enough overall system protection that any other pressure relief valve would only come into play if the issue (blockage) were between the pump outlet and the steering valve.

im running one of these pump on my build and been a few years now and will never go back to an automotive pump for full hydro. i did it all ghetto as well with no bearing block or anything for side load, just an adapter to press a pulley on the pump. do have a pressure valve in line and it returns back to the resi. only issue i have is that steering is not the best at lower rpm when crawling but can fix that with a different pulley so the pump spins faster ect. right now my pulley is stock ford set up so little bit of an underdrive, so when i bang limiter on my motor the pump is seeing just under 7000rpm and holding strong still.

Does anyone have direct comparison between these gear pumps and the blingy CBR w/external pressure relief PSC sells?

Im going to be in the market soon for a 4 wheel steer comp buggy and need a lot of pump for 3x9 DE ram pushing 42s.

got a link to the blingy CBR pump from PSC?

what steering valves are you looking at using?

https://www.pscmotorsports.com/cbr-p...2-in-15-0.html

this is the blingiests CBR pump I can find on the PSC website

https://www.kartek.com/parts/power-s...-1750-psi.html

this is about the blingiest pump on the katek site.

i'm not saying price matters, but the PSC pump is ~$400 and the kartek is over $1k

kartek advertises theirs, and other trophy trucks labeled pumps are shown, as flowing 8 gpm when internally regulated. that is pretty good and those are internally modified to get that flow, hence the price tag. I don't know what the PSC pump is flowing, but likely not 8gpm or else they would be flaunting that. As an example, trail gear has a nice pump that is similar in price to the PSC unit that is billed as flowing 5.5 gpm.

in talking to radial dynamics, he is looking to have a modified CBR pump that will put out about 12-13 gpm at 2500 rpm and up to 15 or 16 gpm at 5000+rpm without any internal regulation. he thinks those are about as much as you can get from those pumps, with modification, based on internal design restrictions. his pumps are also going to be inline with the kartek prices and the rest of that realm. 8gpm from just off idle to red line, regulated, is much easier to plumb for a simple steering system.

if PSC is willing to put some volume information at RPM (or if regulated) for their pump, it would be easier to compare. no real need to get much more pump than you can use, if it can be avoided.

For the effort and the output, an unregulated CBR style pump with modification should get me enough to be happy (low flow hydroboost, mid flow steering, high flow winch all from one pump). with the valves and adapters required to make a gear pump act in similar fashion and be as efficient, the price isn't significantly different once you start getting into high volume as a gear pump will flow substantially more at mid to high rpm than a vane pump if you are setting them up for similar volume at low RPM.

When I emailed PSC about the CBR pump they replied back with that it flows 5.5gpm

hose will do about 5.5 GPM. We don’t have any 8 rib pulleys to offer though.

With my current setup I will be forced to run a single pump on the passenger head (with custom brackets)You have listed the psi for the CBR pump, but what is the GPM flow? I know fittiment is a challenge due the the lsa accessory spacing. Do you offer an offset pulley, or if not, an 8 rib pulley that will allow me to drive the pump off the LSA belt?

awesome thanks for sharing. it seems odd that more MFG don't advertise that stuff

looks like that PSC and the TG (and likely others selling CBR pumps) would provide good results up to (and everything below) about this 14.1 cubic inch steering valve. Midwest Steering recommends 6gpm. Larger displacement valve would just result in slower steering, would it be noticeable? maybe, maybe not depending on what you are doing. racing? Absolutely. trail crawling? be aiight.

edit: to clarify, the valve that is linked is a closed center static load sensing steering valve and was just the first one that i found on MWS that listed disp. and desired min. flow

I don't think or know if my orbital has an internal bypass so would want to run the external relief.

I know that new PSC pump was installed on a recent buggy TC redid and it steers front and rear with zero issues but also was around $800.
