Care must be taken when looking at these recomendations as the DSTHF is especially prone to erosive degrdation th the the areas of the interstage bushing and second stage hub. We have taken extraordinary measures to try and design this suseptability out of this design, but have decided a three stage or greater pump with a properly designed piston assembly is the way to go. The DSTHF or HVX are good choices if erosion is not an issue.
