PHYSICAL PROPERTIES
How to Measure Your Mechanical Seal (Before Ordering)
To match the correct seal, confirm these 4 measurements from your old seal (a caliper works best):
- Shaft size (ID): Measure the inside diameter of the rotary where it slides onto the shaft (ex: 1-3/8″).
- Seat size: Measure the seat OD (outside diameter) and thickness (height) of the stationary seat.
- Working length: Measure the assembled seal’s working length (stack height) from the spring/rotary face to the mating face reference point.
- Rotary OD (if needed): Measure the outside diameter of the rotary assembly (helps confirm clearance in the seal chamber).
Pro tip: If you’re not 100% sure, send a photo of the old seal next to a ruler + your pump model.
