PrecisionFlo XL
Sealant & Adhesive Dispensing System
Notes:
(1) If selecting option 1-5, do not pick option 1 in Code E (110-120 VAC).
Temperature conditioning and electric heat require minimum 200 VAC.
(2) Temperature conditioning system (Options 1-4) will condition and
maintain all components (i.e. hoses, regulators, meters) up to 140ºF.
Operating range 60ºF to 140ºF.
(3) The electric heat system will control 4 zones up to 175ºF.
(4) A heat/cool temperature conditioning system is required to maintain
temperature below ambient.
(5) Temperature control is not available with dual plate Options 6 and 7 of
Code H.
Code H Fluid Module
There are seven different fluid plate choices available on the
PrecisionFlo XL module, those fluid plate choices combined with
the four options for a flow meter in Code J, gives you 28 different
combinations available for fluid metering. All of the fluid modules
are designed to meter and control single component materials.
PrecisionFlo Linear Motor
Option 1 Low Viscosity (PVC): Choose Option 1 to receive the
PrecisionFlo linear motor controlling a tapered needle
and seat designed for low viscosity materials less than
100,000 cps.
Option 2 Med/High Viscosity (Hem): Choose Option 2 to
receive the PrecisionFlo linear motor controlling a
tapered needle and seat designed for medium to high
viscosity materials between 100,000 cps and 500,000
cps.
Option 3 Med/High Viscosity-Integrated Regulator: Choose
Option 3 for high viscosity fluids, where the pressure
required to feed material to the system would exceed
3500 psi (241 bar) in a static state. This will allow the
material to be supplied at a high pressure up to the
inlet of the fluid plate, where it can be regulated down
to 3500 psi (241 bar) or below before entering the
PrecisionFlo fluid plate.
Precision Regulator
Option 4 Low Viscosity (1/2"): Choose Option 4 to receive the
Graco 3/8" pneumatic cartridge style regulator,
designed for low viscosity of typical sealants and
adhesives. This regulator is also ideal for higher flow
rates of low viscosity water-based materials.
Option 5 Med/High Viscosity (3/4"): Choose Option 5 to receive
the Graco 3/4" pneumatic mastic regulator, designed
for higher viscosity sealants and adhesives.
Dual Precision Regulators
Option 6 Low Viscosity (1/2"): Choose Option 6 to receive the
Graco 3/8" pneumatic cartridge style regulator,
designed for lower viscosity sealants and adhesives.
This regulator is also ideal for higher flow rates of low
viscosity water-based materials. This option will configure
the hardware with two fluid plates. Both fluid
plates will be controlled by independent real-time flow
loops within the single PrecisonFlo XL controls. The
flow meter choice in Code J will apply to both fluid
plates if this option is chosen. Temperature control is
not available with this option.
Option 7 Med/High Viscosity (3/4"): Choose Option 7 to receive
the Graco 3/4" pneumatic mastic regulator, designed
for higher viscosity sealants and adhesives. This option
will configure the hardware with two fluid plates. Both
fluid plates will be controlled by independent real-time
flow loops within the single PrecisonFlo XL controls.
The flow meter choice in Code J will apply to both fluid
plates if this option is chosen. Temperature control is
not available with this option.
Code J Flow Meter
Option N None – Pressure regulation only: Choose Option N
when the application requires closed loop control on
pressure only. No flow meter will be included.
Option 1 Spur Gear Meter (30-2000 cc/min): Choose Option 1
when the sealant or adhesive being controlled is able
to run through a spur gear meter. This option will integrate
the Graco G3000 flow meter into the fluid module.
This flow meter is well suited for sealants with
dynamic viscosity of 1000 to 50,000 cps and which are
formulated with fillers of less than 3 mil. Verify pressure
drop by testing.
Option 2 Helical (30-3000 cc/min): Choose Option 2 when the
sealant or adhesive being controlled is able to run
through a helical gear meter. This flow meter is well
suited to most sealants and adhesives from 10,000 cps
to 200,000 cps, and can be used with higher viscosity
materials (up to 500,000 cps) at lower flow rates.
Option 3 Non-Intrusive (100-5000 cc/min): Choose Option 3
when the sealant or adhesive being controlled requires
a non-intrusive flow meter. The non-intrusive flow
meter is a straight tube design without any gears or
moving parts. This flow meter is well suited to most
abrasive or corrosive sealants and adhesives. The flow
meter requires remote stationary mounting from the
fluid plate. This meter can be used with a wide material
viscosity range, from 20,000 to 500,000 cps.
