HOMA Mechanical Seal – 45mm (EMG1 / MG1 Style)

Direct-fit aftermarket replacement mechanical seal for HOMA submersible pump applications that use a 45mm shaft size with an O-ring style stationary seat. This seal is built in the EMG1 / MG1 style, designed to match OEM-style fit and function for reliable sealing performance in demanding pump environments.

Key details

• Shaft size: 45mm

• Seat type: O-ring seat

• Seal style: EMG1 / MG1

Fitment note:

HOMA uses multiple seal designs that can share the same shaft size. Before ordering, confirm your seat style (O-ring seat) and that your original seal matches the EMG1 / MG1 configuration (and verify remaining dimensions if applicable).

Important: If your pump uses a special cup-style stationary seat (not an O-ring seat), you likely need the HOMA 45mm (13mm Thick) cup seat version instead.

If you’re unsure, email us a photo of the old seal next to a ruler and your pump details to info@sealhouseusa.com—we’ll help you match it.
