4. Remove the stationary seal O-ring from the stationary seal.
NOTE: The O-ring usually comes off with the seal in step 3.
Remove Pump Body
1. Remove the two body retaining cap screws.
2. Remove the body from the gear case. If needed, use a plastic
mallet to tap the body away from the gear case, until the
dowel pins are dislodged from the bushings.
3. Slide the body straight off the body studs to prevent
damaging the mechanical seal parts.
To lift the body of a 130, 180, 210, 220, or 320-U3, use a lifting
strap threaded through the ports on either side of the body.
4. Place the body on a protected surface with the seals facing
up to protect the seals.
NOTE: For single mechanical seal, continue. For double
mechanical seal, see page 45.
Figure 44 - Stationary Seal O-ring
The product-side seals and O-rings in a U3 mechanical
seal can be replaced without removing the pump body.
To replace or service these components only, skip to “Install
Product-Side Rotary and Stationary Seal” on page 64.
