Description Description
Select a value that is indicative of the normal size of a batch of the product being
evacuated. The value can be larger than the contents of the container. In this
case, one or more container changes may be required to complete the batch.
Select the air pressure to be applied to the pump when running in Pump Slow
Speed. Slow Speed runs automatically when loading a new container of material
to prime the pump, and at the very end of an empty container.
Select the air pressure to be applied to the pump when running in Pump Fast
Speed. Fast Speed is run to evacuate the bulk of the material from the container.
Select the air pressure to be applied under the ram plate to aid in unsticking the
ram plate from the material or the bottom of an empty drum.
Select the air pressure to be applied to the seal while inside the container. Always
choose the lowest pressure that achieves the desired result. Too much pressure
reduces the life of the seal and creates excessive frictional force opposing
movement of the ram. Too little force may cause material to leak past the seal.
Select the air pressure to lift the ram ram plate out of the container. Choose the
lowest pressure that raises the ram without lifting the container.
Select the air pressure to push the ram down against the product during
evacuation. Always use the lowest pressure that achieves the desired result. Too
much down pressure will cause material leakage around the inflatable seal.
Select the air pressure to be applied to the ram when jogging downward.
Select the air pressure to be applied to the inflatable seal when the ram plate is
approaching an overfull container. Choose the lowest pressure that achieves the
desired result. Setting Seal Partial Pressure too high can cause inflatable seal
damage during entry into the container.
