PRODUCT DESCRIPTION

A Reliable Alternative to the OEM MG12 for High-Temperature Duty

Fitting the MG12 equivalent seal mirrors the original installation — the welded bellow assembly is slid onto the shaft and locked at the specified compression length, with the stationary seat aligned in the gland before final checks, requiring no changes to existing pump housings. Since it's manufactured to match the OEM's exact dimensions, plants already running MG12-fitted pumps can switch over without disrupting spares stock or maintenance procedures. Beyond compatibility, this equivalent gives buyers faster access to metal bellow technology at competitive lead times, with the same resistance to thermal cycling, coking, and elastomer failure that makes the original a preferred choice in hot oil and high-temperature process pumps.
