John Orr 206 Report post Posted January 24, 2006 Has anyone ever used one? General makes a "sixplex" plunger pump - 8 gpm/3000psi. I may consider installing one on my 2-man rig (8gpm-3000psi) allowing me to run each gun independently. or by installing a valve, having all gpms through one gun. Any thoughts?
