MIX/DISPENSE GUNS AND RECIRCULATION OPTIONS
Most systems come standard with two guns but this may not always be the case.
Primary gun is used for mixing and dispensing of the metered materials. The second
gun block uses the same parts as the dispense gun. The second gun block is referred
too as a recirculation gun with the only difference being a bolt-on outlet block that keeps
the two materials separated with hose fittings attached.
Some advantages with the recirculation gun blocks are:
1. Running a ratio check between A & B materials.
2. Releasing the fluid pressure and positioning the fluid piston rods in full down
stroke during shut-down without wasting material.
3. To purge any air out of the feed hoses when changing over to full drum or totes.
4. Temperature control when in-line heaters are added.
High Volume 1:1 Pro gun: This is standard in most cases. Available in automatic and
manual configurations for spray, pour and recirculation operations. No hand held trigger
configuration available because of the weight of the gun.
Standard 1:1 Pro gun: A smaller version of the HV 1:1 gun block capable for up to 12 to
14 lbs/min. depending on materials. Available in a automatic and hand held gun for
spray, pour and recirculation operations. The hand held mix/dispense block uses a air
trigger package which is light weight and easy to handle.
HOD gun: For maximum flow rates for more viscous materials. This gun block is only
available with a manual handle to open and close for pour applications.
MATERIALS A & B HOSE SETS FROM PUMP TO GUN
Hose sets will vary depending on the materials used, length of hoses and the flow rates
required.
•
Standard hoses: Have a black outer jacket with diameters ranging from
3/16” to ¾” diameter. These hoses have a Nylon 11 inner core. Available in
heated hose with a maximum temperature of no more then 120 F. and are
intended to work in conjunction with In-line heater blocks.
•
Stainless exterior braid hose: This hose has a better bend radius then the
standard hose and a Teflon inner liner. Available from ¼” to ¾” diameter.
•
Moisture barrier hose: Moisture lok hoses have a light blue exterior jacket
with a Polyolefin inner liner. These are available from ¼” to ¾” diameter.
Please specify hose diameter, length, hose end fittings and hose exterior when ordering
replacements.
Additional hoses used for solvents, air supply and air signals will typically be
polyethylene tubing from 1/8” to ½” I.D.
