Graco Launches Completely Redesigned Sealed 4-Ball Lower

New Design Reduces Regular Maintenance and Improves Durability

MINNEAPOLIS--Graco Inc. (NYSE:GGG), a leading manufacturer of fluid handling equipment, has just released a new Sealed 4-Ball Lower. The lower is compatible with all Graco® circulation pumps, providing an easy way to upgrade existing Graco pumps. This model has longer maintenance cycles and does not require throat seal liquid (TSL), which reduces maintenance costs and unplanned downtime. Common components also make the lower simpler to maintain and reduce inventory levels on repair parts.

“In industries where unplanned downtime can be extremely costly, our new sealed 4-ball lower reduces the need for routine maintenance,” said Bill Heuer, Graco’s Industrial Products Division Worldwide Product Marketing Manager. “This combination of longer maintenance cycles, no TSL™, and common components takes away the threat of downtime and keeps the system operating longer.”

The lower is completely sealed, so it can be used for every pumping application in your mix room, including catalyzed coatings. It also contains the additional security of a backup seal in case of bellow leakage. “The completely sealed fluid section with bellows provides leak resistance for even the harshest materials,” said Heuer. “This redesign is a game-changer for fast-paced factories using moisture-sensitive materials.”

In addition, the lower features Ultralife Series ceramic coating on its rods and cylinders. “The Ultralife Series ceramic coating is now an industry standard for handling the harshest materials,” said Heuer. “This includes waterborne paints.”

The Sealed 4-Ball Lower is available on all of Graco’s circulation pump assemblies and is compatible with the Bulldog®, NXT®, President®, Viscount®, E-Flo® and E-Flo DC circulation pumps. An open wet cup version is also available, which has many of the same great features as the sealed version.
