I’m looking to see if anyone is running a TSF2019 General Pump. I’m looking to buy one this week to put on my 18HP vanguard motor. The specs say 15EBHP motor minimum? I just want to make sure I will get the full performance out of the pump. With my motor.
GPMxPSI/1100=HP is the most common formula. Put another way, “total ‘cleaning units’ divided by 1100”
18x1100 = 19800 ‘cleaning units’
19800/6.3 = 3143psi.
So you could safely run that pump at around 3000psi with an 18hp motor.
I’m guessing EBHP stands for electric brake horsepower. Electric motors are more efficient and can drive larger pumps/higher pressure vs. their gas or diesel counterparts.
So basically I’m stuck with 5.5 GPM pumps for 3,500 PSI until I get a bigger motor? I do a lot of concrete cleaning and need the psi to run my surface cleaner so I’m still 50/50 about dropping to 3,000 psi to get more gpm on rinsing.
A 5hp electric motor is just about equal with a Honda GX390 so he’d need three to run that 6.3 pump at 36 lol
Ok going to a dumb question.
In regards to the formula
(GPMXPSI)/1100= HP
what is the 1100?
Someone smarter than us came up with that formula. But it is accurate.
It’s just a constant. Like the speed of light, lol.
Basically, you’re first calculating the “cleaning units” of the pump (gpm x psi = “cleaning units”)
Then divide by 1100 to get the required (gas engine) HP requirements.
Remembering that the formula is based on cleaning units will help you use it in reverse if say you want to figure out what your max PSI is for a given HP and GPM, or your max GPM if you have a motor already and a minimum PSI requirement in mind.
