PTK Series Polyethylene Pump Tank Station with Checkmate Control System
The motor shaft is free to rotate, but must be secured to remove the impeller. To
secure the motor shaft, insert a flat bladed screw driver in slot to hold the shaft
stationary (figure 4.2E).
9.
Locate and remove impeller locking screw (figure 4.2F). Using a socket and
ratchet, the impeller retaining screw can be removed. Once the retaining screw
is removed, the impeller can be “unthreaded” from the motor shaft to expose the
pump seal assembly.
10.
Remove all seal parts (figure 4.2G). Note seal component arrangement to
facilitate reassembly.
11.
Clean motor shaft and lubricate with a mild soap solution.
12.
Install new stationary seal member in pump casing cavity (figure 4.2H). The
operator must be certain the stationary seal member is fully squared and seated
in cavity.
13.
Slide the rotating member onto the lubricated pump shaft (figure 4.2I). The
operator must be certain not to damage or tear the rubber bellows assembly.
14.
Place the spring onto the rotating member.
15.
Align the impeller, spring and rotating member before reinstalling the impeller
(figure 4.2J). The operator must be certain the spring and rotating member are
aligned before the impeller is fully tighten and the impeller retaining screw is
reinstalled.
