HFR-Silicone (HFRS)
HFRS models are designed for use with high viscosity, unheated silicone adhesives at flow rates of up to 20 cc/sec.
The equipment can be ran at up to 20 cycles per minute continuous duty.
* Full load amps with all devices operating at maximum capabilities. Fuse requirements at various flow rates and
mix chamber sizes may be less.
** 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 are possible, but should be tested under application conditions.
† Dispense rate in excess of max flow and pressure may result in a machine shutdown due to elevated temperature
of the hydraulic system, resulting in a thermal shutdown (T4H1).
★ approved.
‡ The maximum fluid working pressure for the base machine without hoses is 3000 psi (20.7 MPa, 207 bar). If
hoses rated at less than 3000 psi are installed, the system maximum fluid working pressure becomes the rating of
the hoses. If 2000 psi hoses were purchased and installed by Graco, the working pressure for the machine is
already setup for the lower 2000 psi (13.8 MPa, 138 bar) working pressure by Graco. If the machine was pur-
chased without hoses and aftermarket hoses rated at or above 3000 psi are to be installed, see instruction man-
ual 3A1276 for the procedure to setup the machine for higher rated hoses. The change in working pressure is
made by changing a rotary switch setting in the Motor Control Module. The minimum pressure rating for hoses is
2000 psi. Do not install hoses with a pressure rating lower than 2000 psi.
