help EagleBurgmann MG12 FAQ
How is the MG12 different from EagleBurgmann's MG1 seal?
The MG12 follows the MG1's elastomer-bellows concept but uses an extended bellows tail to meet an EN 12756 fitting length with compatible seats. That dimensional distinction matters when replacing an existing pump seal.
What shaft sizes can an EagleBurgmann MG12 accommodate?
The published MG12 family range covers shaft diameters from about 10 to 100 millimetres. The correct seal, seat and material combination must still be selected for the pump and operating medium.
Can the MG12 handle hot water or chemicals?
Standard configurations are offered for water, wastewater, oils and many process chemicals, with published limits reaching about 140°C and 16 bar for suitable materials. EagleBurgmann also offers the RMG12 variant specifically for hot-water pumps.
Why does the MG12 use an elastomer bellows?
The bellows transmits rotation while accommodating axial movement and protecting the shaft along the seal length. EagleBurgmann lists a movement allowance of about plus or minus 2 millimetres for the MG12 family.
