5 Installation
5.1 General
This is a precision piece of equipment and must be treated as such. Proper installation is necessary to obtain
maximum service life from the pump. To ensure proper alignment, three items are very important during
installation:
1. All machined mating surfaces (such as the mating flanges of the pump and driver) must be clean and
free of burrs and nicks. These surfaces must be cleaned thoroughly with scraper, wire brush and emery
cloth if necessary, and any nicks or burrs must be removed with a fine file.
2. Exterior strain must not be transmitted to the pump. The most common cause of trouble in this respect is
forcing the piping to mate with the pump. It is recommended that flexible connectors are installed in the
piping adjacent to the pump when possible. This is especially critical on type VU (underground
discharge) units where the discharge could be several feet below the supporting structure and a
relatively small strain can cause misalignment.
3. All threads must be checked for damage and repaired if necessary. If filing is required, remove the part
from the pump if possible, or arrange a rag to catch all the filings so that they do not fall into other parts
of the pump. Clean all threads with wire brush and cleaning solvent. Ends of shafts must be cleaned and
any burrs removed since alignment depends on the shaft ends butting squarely. Lubricate all screwed
connections with a thread lubricant suitable for steel. Use an anti-galling compound such as
“Never- Seez” on stainless and monel mating threads.
5.2 Foundation
• The foundation may be constructed out of any material which can afford permanent, rigid support to the
discharge head and can absorb the expected stress that may be encountered during service.
• It is recommended that concrete foundations have anchor bolts installed in sleeves twice the diameter of
the bolt to allow alignment with the holes in the mounting plate as illustrated in Figure 5-1 on page 20,
however, sleeves are not required and anchor bolts may be directly installed in concrete.
WARNING
PERSONAL INJURY
The pump must be installed, operated and maintained only by personnel who are trained
and have sufficient knowledge about the hazards that may occur during such work.
CAUTION
EQUIPMENT DAMAGE
Apply thread lubricant sparingly to male shaft threads only when making up shaft
connections. Do not allow excess lubricant to get in between the ends of the shaft.
