Operation
Find the Proper Agitator Speed
NOTE: Attach ground wire before using agitator.
1.
Fill the fluid supply container to about 3–4 inches (75–
100 mm) above the agitator blade.
2.
Start the agitator, and gradually increase the speed by
turning the needle valve (14) until a vortex begins to
form in the paint.
3.
Reduce the speed slightly, then fill the fluid
container. Use the lowest agitator speed needed for
thorough agitation of the paint. Excessive agitator
speed may cause the paint to foam.
Pressure Relief Procedure
1.
Close the bleed-type air shutoff valve (SV) to relieve
pressure to the air motor.
2.
Disconnect the air line.
Maximum Siphon Flow Rate
The volume of fluid that can be siphoned through the
agitator inlet is determined by the viscosity of the fluid.
•
The maximum flow rate is approximately 12 gpm (45
lpm) with 100-centipoise fluid.
•
The maximum flow rate is approximately 1.2 gpm
(4.5 lpm) with much heavier 1000-centipoise fluid.
To prevent pump cavitation, avoid flow rates higher than
these. Check the fluid periodically for signs of cavitation.
Air Requirements
For continuous use, the 0.75 HP air motor typically
requires 2.5 scfm (0.071 m
3
/min.) of air at 400 rpm or
5.7 scfm (0.162 m
3
/min.) of air at 800 rpm.
Nitrogen Charge the Drum
Operate the Agitator
The bearing nut (8) helps prevent excessive fluid flow
between the siphon tube (4) and helix tube (7), but it is
not intended to be a complete seal. Fluids can pass
through the bearing nut into the gap between the two
tubes. Before you change colors or coatings or store the
agitator, clean the fluid tubes. See Clean the Fluid
Tubes, page 12.
NOTE: Thoroughly agitate the fluid before you use the
suction feature. Agitating maximizes fluid quality and
helps avoid solids getting drawn into the siphon tube
and clogging it. Order part number 236984, strainer inlet
Moving parts, such as an impeller blade, can cut or
amputate fingers. To reduce the risk of serious injury,
always shut off the agitator and disconnect the air line
before moving, checking, or repairing the agitator.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
splashing fluid and moving parts, follow the Pressure
Relief Procedure before cleaning, checking, or
servicing the equipment.
NOTICE
If you are using nitrogen to charge the drum, use a
maximum of 0.25 psi (1.7 kPa, 0.02 bar). Such low
pressure requires special regulation equipment. Use a
passive, non-pressurized system when possible.
Higher pressure could push fluid through the shaft seal
(21) and into the top bearings (11), damaging them.
See Parts, page 18.
