The FLUSH-GARD™ Sealing System from Garlock is an alternative to traditional packing sets in stock pumps, agitators, and other applications handling solid/liquid mixtures. It extends equipment life by protecting sleeve (non-contact) and packing from media attack, while also providing significant cost savings by reducing flush water consumption by up to 90%, as proven with installation of a flowmeter.
Harmful solids and particulate are contained from entering the stuffing box as the flush water is forced by the FLUSH-GARD™ bushings’ unique design – integral tangential multi-porting – toward the pumped media, utilizing the shaft’s rotation and centrifugal forces that are created. A small amount is allowed into the stuffing box to lubricate and cool the braided packing.
The axially split design installs quickly, without equipment disassembly, making it an easy retrofit in existing stuffing boxes (typically no re-machining or redesigning required).
