GM3012 High Pressure Paint Pump Kit, 224524
Quickly convert the GM1030 TexSpray sprayer to an
airless sprayer to spray primer, sealer, smooth elasto-
merics as well as architectural paints, acrylics, ure-
thanes and bonding adhesives at up to 1.25 gpm (4.75
lpm) with 0.035 inch maximum size spray tip at 3000
psi (21.0 MPa, 210 bar) Maximum Working Pressure.
This accessory includes a high pressure pump, fluid
filter, optional filter screen, drain valve and pressure
control. See Fig. 4.
The system requires an airless spray gun and tip
guard and an airless spray hose with spring guards on
both ends. These accessories must be rated for at
least 3000 psi (21.0 MPa, 210 bar) working pressure.
Switching the pumps takes about 5 minutes. Refer to the
manual 308127, supplied with the kit, for specific warn-
ings, setup, operating and repair procedures.
Compressor Requirements
NOTE: This sprayer will not operate without an external air compressor.
Air compressor range: 5 scfm to 35 scfm, 40 to 100 psi (0.2–0.76 MPa, 2 to 7.6 bar)
Material
Air Requirements*
Elastomerics 25 scfm at 90 psi
(textured) (0.7 m
MPa, 6.3 bar)
Simulated 15 scfm at 60 psi
Accoustical (0.42 m
MPa, 4.2 bar)
Splatter Coat and 10 scfm at 40 psi
(0.28 m
Knockdown MPa, 2.8 bar)
Orange Peel 15 scfm at 60 psi
(0.42 m
MPa, 4.2 bar)
* Material, temperature and volume affect the cfm needed to properly atomize the material.
Fluid Nozzle and Spray Disc Selection
Three spray discs and nozzles are supplied with the sprayer. The nozzles are numbered 1, 2 or 3 – the larger the
number the more scfm is required. These parts can be interchanged to produce a pattern suitable for each job.
Refer to Steps 7 and 8 on page 9 to fine tune the spray pattern.
