130-U3 and smaller pumps: Install Seal
Components (single mechanical seal)
NOTE: SPX FLOW recommends
replacing elastomers every time the
pump is serviced.
NOTE: For single mechanical seal on 180-U3 and larger pumps,
see page 43. For double mechanical seal, see page 45.
1. Lay out the required parts for each seal (040-U3 shown).
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.
2. Install the shaft ring with the notch openings facing toward
you as shown in Figure 54.
NOTE: Make sure the notch openings in the shaft ring are
perpendicular to the ports, and in line with the bores. See
Figure 60 on page 42.
3. Figure 55 shows the shaft ring installed.
