. 2.

Stainless Steel Frame: supports the cardboard or 
collapsible bin.

Pneumatic Control Panel: contains pneumatic 
controls to regulate the air pressure to pump air 
motors, ram, and ram plate seal in order to control:

•

pump air motor pressure

•

pump speed control

•

ram up and down pressure

•

seal pressure

Electronic Control Panel: is connected to the 
pneumatic control panel with the 24 VDC cable 
supplied. The panel uses 110 VAC input (20 amp 
circuit). If a flow meter is used, it must also be 
connected. The electronic control panel sends 
signals to:

•

turn the pumps on or off

•

inflate or deflate the ram plate seal

•

raise or lower the ram plate

•

turn off the air supply to the ram plate so the 
ram can slowly lower into the bin

Sanitary Pumps: pump material from the bin to the 
target application.

Air Cylinder: raises and lowers the pumps and the 
ram plate in and out of the material container.

Ram Plate: applies an even amount of pressure to 
the material in the bin. When the ram plate seal is 
inflated, it creates a seal. The ram plate presses 
down on the material in the bin to assist the pumps 
in delivering the material.
