Pump Packing

1830-SSP Slurry Packing

Chesterton 1830-SSP Slurry Pump Packing is manufactured with a hybrid yarn combining advanced, expanded graphite PTFE yarn with carbon yarn reinforcement. This unique construction of yarns yields a packing that is easily removable during repack resulting in reduced downtime. 1830-SSP is applicable in a wide range of slurry sealing applications.

FEATURES

Advanced Expanded Graphite PTFE, Carbon Reinforced Packing
Developed to meet rigid demands of slurry sealing applications
Low friction, less heat generation non-abrasive, saves shafts and shaft sleeves
Low leakage and long life

2211 DualPac Severe Slurry Packing

Chesterton DualPac™ 2211 mechanical packing is built to address these issues by combining two complimentary materials in one packing. Using Chesterton's patented braiding technology graphite filled ePTFE can be placed against the shaft where it provides superior sealing and low friction, and a high strength and resiliency aramid is placed against the stuffing box bore to resist consolidation without shaft wear. Both lab and field tests have shown that DualPac requires fewer gland adjustments, resulting in drastically extended life in severe service applications.

FEATURES

Achieves significantly longer packing life
Low friction and gentle on shafts
Resists consolidation and extrusion
Multiple configurations to eliminate need for end rings
Exclusive design using DualPac packing technology
