Filter Press Overview: Introduction to the filter press: How it Works.
Closing Stage 1: Closing the filter press with the hydraulic pump.
Closing Stage 2: Final filter press closing stage allows the hydraulics to reach the desired closing PSI.
Air Blow-Down Stage: Activating the filter press air blow-down manifold system
Semi-Automatic Plate Shifter
The Semi-Automatic Plate Shifter rolls on rails that are outside of the filter press side bars. This plate shifter is positioned manually by the operator such that the separation paddles are under and between the plates that need to be separated. Once in position, the operator presses the button which activates the pneumatic operation. The paddles rise up between the plates and then extend out to separate the plates. The operator releases the button and the paddles retract. Once the operator verifies that the sludge has fallen, and that the cloth is in good condition and that the O-Ring is intact and in good condition, the operator then moves the plate shifter to the next plate, and the process is repeated.

Automatic Plate Shifter, Pendant Controlled
The Pendant plate shifter is mounted to the press sidebars and operates with a hand held control (pendant). The plate shifter allows for easy movement of filter plates during the cleaning process. This is especially important when you have a large capacity press with large, heavy plates.
The operator puts the shifter at the handle of the plate he/she wants to move and then presses the shift button which will push the plate apart from the pack. The process is repeated down the pack until the press has been emptied.
The Pendant plate shifter allows for easy one person operation during the filter press cleaning cycle.

Fully Automatic Plate Shifter
The Fully Automatic Plate Shifter, operates similarly to the Pendant Shifter but allows the operator to press a button to activate the shifter. Each plate is pushed to the end of the press one at a time. The Fully Automatic Plate shifter is complete with a safety shut off. The electric eye light curtain will shut down the shifter if someone is in the way.

Our final plate shifter is the Super Shifter. This shifter is similar to the fully automatic plate shifter but has more bells and whistles and has PLC controls. The Super Shifter, in addition to moving the plates for cleaning, also has a bumping and washing mechanism. The electric light curtain is also standard on this design.
The bumping mechanism on the Super Shifter means the operator does not have to scrape each individual plate for cleaning. The bumper is built into the shifter, and when activated, will bump one handle of the press and then the other side. Each side gets bumped twice to help release any stubborn sludge.
The automatic wash cycle on the Super Shifter cleans the plates one chamber at a time. For the Super Shifter, Bombay Doors are required for the Wash Cycle. The doors must be closed. The control is then set to Wash Cycle and the shifter will move the first plate away from the pack. The washing mechanism will clean the plates from the top to the bottom. If desired, you can have the washing mechanism activated back up the plate for very soiled cloths. The water from the wash cycle flows to the bottom of the press to troughs on either side of the filter press frame. Once the first chamber is cleaned, the plate is pushed to the head (feed side) of the press and the shifter will then recognize and grab the next plate to be cleaned.

Bombay doors are used underneath the filter press to catch any “dripping water” that may come out of the plates during operation. These are typically used with non-gasketed filter presses as our gasketed style will not leak as the non-gasketed will.
