Adjusting the Capacity of Your Filter Press

Many of our customers purchase an expansion piece upfront because they want the flexibility to ensure they can meet their company’s production goals even if they are not 100% sure of production rates or have uncertainty in the numbers for initially sizing the press. Perhaps you can relate.

This 630 mm filter press is shown with an “expansion piece” to allow for additional plates. On a smaller capacity filter press such as the 630 mm, when this expansion piece is removed, adding more filter plates to the press allows you to increase press capacity.

What Kind of Capacity Increases Can I Expect?
With the 630 mm filter press, when removing the expansion piece, it is not uncommon to be able to literally double the press capacity. On 1200 mm filter presses, use of the expansion piece may yield an additional 10% bump in capacity, which can make all the difference. The expansion piece ranges in price between $800 and $1800, depending upon the diameter and length; it is a minor expense given the flexibility that it affords. Besides getting the expansion piece, what you essentially are also getting is an upgrade to the main frame of the press to accommodate future expansion.

What If I Need to Decrease the Capacity of My Press? Can I Simply Remove Plates?
The short answer is no – you cannot simply remove plates. However, Micronics can provide you with a blanking plate (back-up plate) if you need to reduce the capacity of your filter press. A blanking plate is a 2” or 3” thick polypropylene slab with handles.

You may find that your filter press frame is too big for your application, which makes filling the chambers more difficult. A blanking plate is useful for this situation as well. By incorporating the blanking plate, customers can “short stack” their press to reduce press capacity to meet their current production needs.

Whatever your situation, Micronics’ pressure filtration experts can help you with adjusting the capacity of your filter press to meet your operating conditions.
