Graco 4-Ball Pump
Technology

High Performance Industrial Pumps

4-BALL PISTON PUM P LOWERS

Graco’s positive displacement

piston pumps provide low cycle rates

and high flow as the pump displaces

fluid in both directions of the stroke.

This versatile technology is used in

a wide range of applications.

Graco’s new 4-ball piston pumps

produce low shear output for

shear-sensitive materials in low

pressure, high flow applications.

Typical applicaTions

• Paint circulation

• Fluid transfer and supply

Typical Fluids Handled

• Waterborne paints

• Solventborne paints

• Acid catalyzed varnishes, enamels and lacquers

THE LATEST IN LOW PRESSURE, HIG H FLOW TEC HNOLOGY

GRACO IS MAKING IT EASIER to install and maintain your 4-ball pump. Not only can all lowers be

used with pnuematic, hydraulic and electric platforms, many models have

COMMON COMPONENTS –

making cylinders and pistons easily interchangeable between pump sizes.
