HexaTech MG Type Seal

The MG-Series Precision Mechanical Seal is an industry-standard, elastomer bellows shaft seal engineered for centrifugal pumps, agitators, and rotary process machinery. Renowned for its compact footprint and robust construction, the MG-Series provides superior leak prevention, accommodates shaft deflection, and protects rotating equipment from premature wear.

Key Specifications & Features

Modular Series Variations
Available in standard industry lengths—MG1 (standard length), MG12 (extended bellows length), and MG13 (compact short installation length)—to seamlessly fit varying stuffing box depths.
Non-Fretting Elastomer Bellows
The rubber bellows design eliminates dynamic O-ring friction on the shaft sleeve, preventing shaft scoring and accommodating axial and angular runout.
Self-Cleaning Single Coil Spring
Heavy-duty, un-clogging central spring mechanism ensures uniform face-loading pressure even when handling dirty, viscous, or particulate-laden fluids.
Standardized G60 Stationary Seat Compatibility
Designed to pair with standard G60 cup-mounted stationary seats for quick replacement and DIN 24960 interchangeability.
