Automatic Filter Press and Pump Control System

Met-Chem’s Automatic Filter Press and Pump System Control Panel gradually increases the pump pressure up to 100 PSI for standard units. This allows for even filling of the filter chambers and consistent cake quality. This system frees up the time of the filter press machine operator to perform other tasks. In addition, Met-Chem offers various Filter Press Plate Shifters.
 
The Met-Chem Automatic Filter Press and Pump Control System is used in conjunction with an air operated diaphragm pump to automatically increase the feed pump pressure at predetermined intervals during the filter press filling cycle. If the pump runs at a higher initial pressure, the filter cake will become a packed layer of solids on the filter cloth. This will restrict the flow of the slurry thereby creating a very dense coating of the filter cake.  This can cause the cloths to blind off and not allow further filtration.  Starting at a lower feed pressure allows a soft layer of slurry particles to be deposited on the filter cloth.  This initial layer becomes the filtering media which will enhance the filterability of the incoming slurry.

This system can be incorporated with a new Filter Press from Met-Chem, a used unit, or even your own existing press.

The automatic pump control system automatically and gradually increases the feed pressure in four stages during the filling cycle.  These stages are adjustable to suit your slurry and solids concentration.  However, it is commonly set at increments of 25 psi.  (25, 50, 75, 100).  By monitoring the feed pump flow sensor, during the final pressure stage, the operator will be able to determine the cycle completion.

The Automatic Pump Control System also incorporates a low hydraulic pressure safety shut down the device.  If there is not enough hydraulic clamping pressure present, the system will completely shut down, eliminating any possible leaking from between the filter plates.

The pump control system allows your filter press to run at its optimum efficiency creating dryer filter cakes, reducing disposal costs, reducing operator time, and increasing the life of your filter cloths and feed pumps.

This system can be incorporated with a new Filter Press from Met-Chem, a used unit, or even your own existing press.

Automatic Filter Press with Plate Shifters

Our standard filter presses can be operated manually. Met-Chem manufactures four types of Filter Press Plate Shifters to make operating your filter press easier, safer, and more efficient. Manual filter presses require more time and attention than the same filter press with an automatic plate shifter.

For some larger presses, we can build a catwalk along with the disposal chute in order to accommodate a roll-off container. For more filter press automation, look at our Automatic Filter Press Pump Control System

The Met-Chem Fully Automatic Plate Shifter allows you to empty the filter press with little to no operator presence. With large filter press plates, it would take two employees to move each plate and empty the filter press. The plate shifter reduces labor costs, improves efficiency, and it is safer than other shifters. As a result, the fully automatic plate shifter will Save You Money.  

For added safety, a light curtain can be added. If a person or an object breaks the plane of the curtain, the shifter will automatically stop.

Met-Chem can add-on, rebuild and retrofit your existing filter press with a Fully Automatic Plate Shifter.

The Fully Automatic Plate Shifter uses a PLC control panel to automatically empty the filter press. The load sensing carriage will grab and shift each plate, and it will allow the sludge to fall. This is a great time saver for companies that want their employees doing more productive work than emptying the filter press. Watch the video to see the fully automatic plate shifter in action.
