    Can I use a VFD on a single phase pump?

    Hello, I'd like a way to control the flow of this pump https://www.piusi.com/products/panther-ac. I read that VFD only works on the three-phase pumps, this model is available in 3 phases but it's utterly expensive. Wonder if there's a way to control a single phase?

    Does anyone know a good affordable pump that is FKM/Viton sealed?

    Adjust LPM in my pump.

    Hello, My pump is rated for 5-30 LPM. However, the system I'm using only requires a flow of 5 LPM. What are the ways to make sure my flow remains at 5 LPM knowing that my pump is a plug and play? No switches.
