Great experience

   Diefenbach is developing from over a century, exactly since 1907. This development is concretized in design and in a production of machineries for “sludge” filtration and dehydration.

   The company ownes its name to the founder, Giorgio Diefenbach, who, at the beginning of the XX century in Monza (near Milan) opened a factory for presses production.

   The target of the presses was the squeezing of the olives, process that needed, at the end, the “cleaning” of the product through the aid of filter presses, also made by Diefenbach.

   In the 1950 the company focuses the production exclusively on the filter presses, able to filtrate oils and purifies the industrial wastewater.

   From the beginning to the present, Diefenbach has been able to develop a know-how to allow itself to product over than 50 machines per year that operate in all the fields where the filtration is necessary. These fields range from Mining to Food Industry, each filter press borns to satisfy the specific requirements of our customers.

We preserve the principles and the approach for more than a century

OUR ADVANTAGES

DIEFENBACH RECESSED FILTER PRESS 

THE BEST CHOICE FOR THE DEHYDRATION OF SLUDGE WITH HIGH SUSPENDED SOLIDS CONCENTRATION IN THE INLET AND LOW MOISTURE IN THE FINAL PRODUCT.


The recessed filter press functioning is based on the high pressure filtration method. In the present Industry it’s the most widespread type of slurry dewatering machine.
High Production Capacity Filter Presses

Reliability is the line guide that identifies Diefenbach filter presses. 

Especially the high beam filter presses that guarantee maximum solidity  

and high performance.


The high capacity allows the installation of a maximum of 

180 plates 2500 x 2500 mm with a filtration pressure over than 16 bars.

• 200 tons of dehydrated product in one hour.

• 35 m³ volume of discharged product each cycle.

These are some performance examples of 

Diefenbach filter presses in mining field.

FILTRATION TEST?

We help you to choose the right filter press

To be able to size the best filter press it is necessary to know all the cycle parameters.

The tests we make in our laboratories offer the opportunity to simulate every process scenario (recessed plate and mix membrane plate with different thickness of the chamber, washing cake, squeezing and blowing of the cake).

 Tests help us to choose the best cloth for your sludge and help us to optimize parameters like working pressure and temperature. 

The versatility of our pilot filters offers the opportunity to make tests directly from our customers using a little quantity of sludge.  

 All these skills are a further added value to the effectiveness of the Diefenbach method.
Accessories and consumables for filter presses
Wide range of equipment and accessories available for Diefenbach filter presses: feeding pump, skids for the washing of the cake, skids for the washing of the cloths, poly stations, screw conveyors and belt conveyors, filter cloths and spare parts.
