Performance — Will It Do What You Need?

Franklin publishes this model’s performance as curves, so this page does not reproduce figures read off a plot. Send your flow and the head you need and we will select from the published curve.

Before You BuyConfirm horsepower, voltage and phase against your service, and the connection size against your piping. Single-phase and three-phase units are not interchangeable.
