130-U3 and smaller pumps: Install Seal
Components (double mechanical seal)
NOTE: For double mechanical seal on 180-U3 and larger pumps,
see page 57. For single mechanical seal, see page 40.
1. Lay out the required parts for each seal (Figure 83 shows
parts for one seal, on a 040-U3 size pump).
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 84.
NOTE: Make sure the notch openings in the shaft ring are
perpendicular to the ports, and in line with the bores. See
Figure 90 on page 51.
3. Figure 85 shows the shaft ring installed.
