@Atlas1, just curious about the process for upgrading pumps on the GX390… Do you buy the 5.5 gpm pump WITH the gear drive already installed on it?
Or do you buy a direct drive pump and put a gear reduction box on? I’ve been looking online at them and I mostly see pumps without gear drives, and I sometimes see the gear reduction boxes themselves.
If you put a gear reduction box between a GX390 and a direct drive pump, will it then draw water from a buffer tank, or does the pump have to be specifically designed as a gear driven pump? I’m just not sure because physically the direct drive pumps and the gear drive pumps all look the same to me, mines the shaft housing on the direct drive and the gear box on the gear driven pumps. Both look like direct bolt-on attachments to a generic triplex pump.
I saw that IBS was suggesting this pump. Looks nice. I’m just trying to understand if the pump has to come with the gear reduction or if they can be purchased separately.
Any experience or knowledge shared would be greatly appreciated!
PS…Does anyone know what happens if you put a gear reduction box on a 4gpm/4000 psi pump?
