Installation and operating instructions SIL, DIL, PBS
• Loosen the motor fastening screws (Fig. 1/2/3/4/5, item 5) on the
motor flange and lift the drive off the pump with suitable hoisting
gear. On few PBS pumps, the adapter ring comes loose (Fig. 3, item 8).
• By loosening the lantern fastening screws (Fig. 1/2/3/4/5, item 4),
dismantle the lantern unit with coupling, shaft, mechanical seal and
impeller from the pump housing.
• Loosen the impeller fixation nut (Fig. 1/2/3/4/5, item 1.11), remove
the washer (Fig. 1/2/3/4/5, item 1.12) beneath it and pull the impeller
(Fig. 1/2/3, item 1.13) from the pump shaft.
• Dismantle the shim (Fig. 4/5
,
(Fig. 4/5 item 1.43).
• Pull the mechanical seal (Fig. 1/2/3/4/5, item 1.21) off the shaft.
• Pull the coupling (Fig. 1/2/3/4/5, item 1.5) with the pump shaft out of
the lantern.
• Thoroughly clean the sliding/seat surfaces of the shaft. If the shaft is
damaged, it must be replaced.
• Remove the stationary ring of the mechanical seal with the sealing
collar from the lantern flange, as well as the O-ring (Fig. 1/2/3/4/5,
item 1.14) and clean the gasket seats.
Installation:
• Press a new mechanical seal stationary ring with collar into the gasket
seat of the lantern flange. A commercially available dishwashing liquid
can be used as a lubricant.
• Install a new O-ring in the groove of the O-ring seat of the lantern.
• Check the coupling sliding surfaces, if necessary, clean and slightly oil
them.
• Pre-install coupling shells on the pump shaft with shims inserted in
between and insert the pre-assembled coupling/shaft unit carefully
into the lantern.
• Pull a new mechanical seal onto the shaft. A commercially available
dishwashing liquid can be used as a lubricant (if required, insert the
key and the shim again).
• Install the impeller with washer(s) and nut, countering at the impel-
ler's outer diameter while doing so. Avoid damage to the mechanical
seal due to jamming.
• Insert the pre-assembled lantern unit carefully into the pump housing
and screw together. As you do so, hold onto the rotating parts of the
coupling to avoid damage to the mechanical seal.
• Slightly loosen the coupling screws. Slightly open the pre-assembled
coupling.
• Install the motor with suitable hoisting gear and screw the lantern/
motor (and adapter ring for few PBS pumps) connection together.
• Slide the forked spacer (Fig. 19, item 10) between the lantern and
coupling. The forked spacer must sit there without any play.
• First, slightly tighten the coupling screws (Fig. 1/2/3/4/5, item 1.41)
until the coupling half-shells are in contact with the shims.
• Afterwards, screw the coupling together evenly. In doing so, the
specified distance between the lantern and the coupling of 5 mm is
automatically adjusted via the forked spacer.
• Remove the forked spacer.
• Install the coupling guard.
• Connect the motor or mains connection cables.
