FEED AND DISCHARGE CONNECTIONS
To prevent damage to the centrifuge and piping system in case of centrifuge imbalance, vibration
isolation is required. Consequently, flexible connections must be used for all feed and discharge
connections. A source of fresh water or oil is to be connected to the flush fitting on the feed
component for flushing the centrifuge prior to shutdown. A shutoff valve must be installed in the
flush piping.
The feed component (Figure 3022-6) supplied with the centrifuge has female connections to
accept the customer’s feed and flush piping and an integral flex joint for vibration isolation. The
liquid discharge chute, which is customer supplied, also requires a vibration isolator. If a solid
discharge chute is used, it must be connected to the solids discharge chute through a flex
connection. Refer to drawing 16590-00 in Section 11 for liquid and solid discharge chute
connection flange dimensions and bolt patterns.

FEED PUMP
A positive-displacement feed pump is required to supply the centrifuge. Refer to DER01321 for
feed pump specifications.
LIQUID DISCHARGE PUMP
If a centrifugal liquid discharge pump is used, sizing must take into account the aeration
properties of the centrifuge. Be sure to size the centrifugal pump adequately to avoid cavitation
due to the natural aeration properties of the centrifuge.
