Graco ’s positive displacement piston pumps have been designed to provide low cycle rates and high flow as the pump displaces fluid in both directions of the stroke, allowing them to be used in a wide range of applications.

Producing low shear output for shear-sensitive materials in low pressure, high flow applications including paint circulation and fluid transfer, these displacement piston pumps can handle fluids such as:

  • waterborne paints
  • solventborne paints; and
  • acid catalyzed varnishes, enamels and lacquers.
Many models of these four ball pumps feature common components, allowing easy interchange of cylinders and pistons between pump sizes.

Additional features are also supplied as standard on these displacement piston pumps, such as an enclosed wet cup, stainless steel seats and spring loaded packings.

The new enclosed wet cup technology maintains consistent lubrication for packings, minimising operator interaction to ensure reduced maintenance costs.

Spring loaded packings increase the life of throat packings in these pumps, delivering consistent torque with no need for operator adjustments.

The supplied lubrication bottle is see-through for visual checks, with a screw-in design for easy access and refill.

Four ball displacement piston pumps from Graco can be used with pneumatic, hydraulic and electric platforms.
