How to get info about Low Flow High Head Pump
- Thread starter Edpatch
- Start date
A couple of choices would be PD (piston type pump) or a high speed centrifugal like Sundyne.
Efficiency on the Sundyne will be a lot lower than the PD but you'll have the ability to modulate flow directly by throttling the pump discharge where the PD would need a recirculation loop.
There are a lot of other people much more experienced in this than I am, will be interesting to see if I'm close

What are you pumpin?? What is the liquid temperature & properties ???
At 1300 psid, you are into a small multi-stage centrifugal pump design...... kind of like a small boiler feed pump for a 30,000 lb/hr boiler
Try Goulds pump......they offer the model 3935 which is a horizontal axis, multi stage centrifugal unit. Also look at the multi-staged (radial split) ring pump.... the model 3310.
I believe Ingersol-Dresser pump (now owned by FLOWSERVE) has a similar models...... try
Consider a used boiler feed pump.... they are available from cancelled/scraped power projects.
Also, give some thought to minimum flow protection devices.... you will have the same problems as the boiler feed pumps do.....
Good Luck

For high head, low flow applications handling clean fluids, a good option is the Rotojet pump -
DiaphragmPumps
Industrial
To spec a pump capable of delivering 60gpm against a back pressure of 1300 psi, you need to decide which route to go down, If it has no particulate and an SG similar to water then a multistage centrifugal pump is suitable as long as you have enough space to fit a motor the size of your house, if there is a small amount of particulate or a higher viscosity, a high pressure diaphragm pump like the Wanner Hydracell would be preferred, if the flow needs to be variable or you require a more energy efficient option then a Piston/Plunger Pump would be my pump of choice.
