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.

. 7.

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.
