Just got my new udor pump in and I have 2 questions.
-
It says to dual feed this pump. Do you guys feel like this os necessary?
-
I notice what looks like mounting threads at the bottom of this pump? Are you guys mounting this to anything?
No and no

I must humbly disagree with @DisplacedTexan. If you look at the plunger pump installation guide on the Udorusa.com website they indicate that dual feeding is a requirement for 7 gpm and above pumps. Additionally, on the installation guide under the “mount” section they indicate support rails or a torque plate is required. I know there are people that disagree with this but like you I spent $1000 for a gear driven plunger pump and wasn’t going to take the chance of voiding a warranty. My two cents. Besides, does it really take that much more work to dual feed it and throw some support under it? It weighs 55 lbs. why chance it?

The shaft supports the weight of the pump. Support rails couldn’t hurt but they’re not necessary either.
I’ve never dual fed any single pump I’ve had my hands on and have yet to see any issues with starvation other than operator letting the tank run dry. Besides, isn’t Udor the one that claims their pumps can run dry with no major damage to the pump internals? If that’s the case, 1" or bigger single inlet should be more than sufficient.
Either way, I don’t think you could do any harm.

Zero reason to dual feed with an 8gpm. Our udor rep said that wording is there because of the number of people that try to feed with less than 1" lines and because so many use poly braided hose.

Agreed on both counts with those above. No need for dual feed or supports. I did add 4 extra bolts in my install of the gear drive to the motor, but even that is really overkill. A 1 1/8” shaft can support the pump weight easily.
My udor pushes 9+ gpm with low pressure nozzles and bypassing the injector.

Will you send me a picture of your steel skid base plate? Going to fab my own out of 3/8 but would like an idea or two.
Here’s an idea for your skid. Super small footprint and low profile, and won’t rust
And some more info/pics further down in that thread:

Thank you sir.
Udor states that the minimum feed line size for the 8gpm pump is 1 1/4 inch. I only ran 1 inch to my 3024gr, so I did dual feed it. It was simple to do, so why not. I’ve been ordering some packing insertion tools from Udor and received the wrong one so I was on the phone with them today. I happened to ask Shane if dual feeding is necessary on the 8gpm and he said that a single feed should be adequate in most cases, but you can only benefit from dual feeding it. As far as the torque plate goes, he said that it is an absolute necessity to either mount the pump with rails or use the torque plate. Under high pressure, the torque on the pump can cause the case to flex, sometimes to the point of actually breaking the case. When I got my first 3024gr pump, I contacted Udor about the torque plate recommendation, and whoever I spoke to said it wasn’t necessary for my combination of engine and pump. I guess a 690 isn’t considered high hp. So now I’ve got two conflicting recommendations. I have two Udor gr pumps that I’ve been using for the past year and a half without torque plates. Both pumps have developed small gear oil leaks between the gearbox and the pump. When I say small leak, I’m talking maybe a drop or two on the baseplate after 5 or 6 hours of runtime. Whether it’s related to the torque plate or not, I don’t know.
