Centrifugal Pump (Option)
The pump must always run in a “flooded” condition.
Operating the pump in a “non-flooded” condition will
cause severe seal damage and possible pump damage.
A “flooded” condition is when the centrifugal pump is
completely full of fluid and no pockets of air are present in
the pump.
To verify that the pump is flooded, visually check the
pump vent line for fluid. Fluid will appear in the vent line
when pump is flooded.
In order to get maximum pump efficiency, the mounting
and plumbing must meet the following guidelines:
Figure 33
The pump inlet must be mounted below the product tank
sump to allow gravity to naturally fill the pump with liquid
[Figure 33] .
The suction line must have a continual rise from the
pump inlet to the tank sump
[Figure 33] .
The pump must have the vent line plumbed to it [Figure
33] .
Figure 34
An air trap point will occur if the suction line does not
gradually rise from the pump inlet
[Figure 34] .
