EVERGROW EG-250 Stuffing Box — Precision Sealing for 250-Series Centrifugal Pumps

The EG-250 Stuffing Box from EVERGROW is engineered to provide reliable sealing performance for 250-series centrifugal pumps widely used in drilling operations, industrial fluid transfer, mining, and general service applications. As part of the EVERGROW EG-250 pump family—known for its durability, interchangeability, and stable operation—the stuffing box plays a critical role in maintaining pump efficiency and extending service life.

Designed for Versatility and Easy Maintenance

To meet different operating requirements, the EG-250 Stuffing Box is available in two configurations:

• Stuffing box for mechanical seals

• Stuffing box for packing seals (Stuffing Box, packed)

The packed version includes a tapped opening to the lantern ring, allowing the user to connect a grease lubrication line or a flush line. This feature helps maintain the correct lubrication and cooling of the packing, especially under high-load or abrasive conditions common in oilfield and industrial environments.

The stuffing box is designed to be easy to install, remove, and service, reducing downtime during pump maintenance or seal replacement. This makes it ideal for both pump repair shops and end users who require dependable, field-serviceable parts.

Fully Interchangeable With Major Brands

EVERGROW manufactures the EG-250 stuffing box with strict dimensional control, ensuring full compatibility with industry-standard pumps. Our stuffing box directly replaces:

• MISSION P/N 22223-01-30, 20614-01-30
