HydroBlend™ system for richer 1:1 dilutions

057 System.  The HydroBlend™ 057-L6850-AV/F6850-AV Proportioning System consists of two 6850-AV pumps, one variable ratio, one fixed ratio, acrylic pump heads, viton seals, maximum chemical:water ratio 170:128, maximum flow 7 GPM @ 75 psi, vertical mount.  Mounted on a poly board, with by-pass plumbing to run either single or dual injection.  It also comes with a water pressure regulator, water T-filter, and complete plumbing attachments.

These systems are designed to run open to the atmosphere with a minimum 1.0 inch I.D. discharge line.  Deviation from this set-up will restrict the pump's flow, causing the pump not to cycle correctly.
