CP-5

The CP-5 is a simple, lightweight, very compact, yet inexpensive grouter. Its portability makes it ideal for pumping polyurethane resins in low volume, yet high pressure, applications. The CP-5 primes quickly because the inlet check valve is submerged, and not aloft where it must depend upon suction for initial wetting and sealing. A dual fulcrum setting pumps .41 ounces per stroke at up to 3,000 psi., or .62 ounces per stroke at 2,000 psi. A vent cock at the outlet check valve relieves pressure in the dispense line for ease of disconnection of the packer connection The balls within both the inlet and outlet check valves are ceramic: lighter than steel, yet harder than steel! The light ceramic inlet ball requires less vacuum to lift it from its seat – and keep it off as well. In addition, there are no seals commonly found in check valves. Instead, the valve seats are lapped. And, both valve bodies separate cleanly in the center for ease of cleaning. The frame construction is welded stainless steel. Other components are corrosion free stainless steel, brass, and hard coated aluminum. The stand support pivots to lock into alignment with the frame. Overall transport / storage dimensions are 36” x 24” x 2 1/2”, and the weight is only 27 pounds. It also comes with a 15′ dispense hose.

Most pump flushes supplied by polyurethane manufacturers are a blend of solvents, making it very difficult to find seals to withstand.  Therefore Lily recommends cleaning the CP-5 Grouter with Xylene or Xylol.  Place the inlet valve into a small pail of the solvent.  Pump the solvent and polyurethane within the unit into a waste bucket until the solvent appears.  Redirect the flow into the solvent pail for a minute or so.  Discard the solvent/polyurethane mix in the pail.  Place fresh solvent in the pail and recirculate again.  This second pail of solvent can then be used for the initial cleaning the next time.  Solvents left in the dispensing hose can cause it to deteriorate prematurely.  It is recommended that the solvent is flushed out with a final flush using hydraulic fluid or cooking oil.”
