Models
HFR-Laminate (HFRL)
HFRL models are designed for use with low viscosity, unheated urethane laminating adhesives at flow rates of up to
30 cc/sec (4 lb/min) @ 1500 psi (10 MPa, 103 bar).
** Cycle rate should be between 8 and 20 cycles per minute. Max flow rate is determined for continuous service at
120°F (39°C) at stated cpm and pressure. Higher cycle rates are possible at lower temperatures/pressures and
intermittent use. Lower cycle rates may be possible, but should be tested under application conditions.
†
Dispense rate in excess of max flow and pressure may result in an elevated temperature of the hydraulic system,
resulting in a thermal shutdown (T4H1). Other system models are available for sustained flow rates and pressures
in excess of above.
