ESD (Cartridge Mounted Double Mechanical Seal)

The SEPCO ESD seal is designed as a double seal for use in corrosive applications which require positive lubrication without dilution of the pumped product.

Slotted Glands: The slotted gland offers more versatility with bolting patterns.

Extreme Corrosion Resistance: The metal parts of the seal are isolated and not wetted by the pumped product. Standard alloys can be used, which makes the ESD an economical alternative to double seal designs which must utilize exotic alloys.

Abrasion/Corrosion Resistant Faces: The inboard seal faces of the ESD are made of carsil and silbide. These face materials offer excellent resistance to both abrasion and corrosion.

Fits Narrow Stuffing Boxes: Permits use in smaller ANSI pumps without equipment modifications, including those with 5/16″ cross section stuffing boxes.

Ease of Installation: The seal is pre-assembled and set at the factory. Mechanics are not required to make critical installation measurements in order to install the seal.

Impeller Adjustments in Service: Disassembling the pump is not necessary to make impeller clearance adjustments.
