Portfolio Summary

Our unique portfolio of two filter press technologies allows us to select the machine that is best suited to your specific process application and requirements. Each typology then boasts a number of different features and optional equipment that enable us to finely tailor and customize the machine to your specific application.

In addition, each machine can be built in a variety of different material types (from carbon steel to stainless steel to high-alloyed steel grades) or coated and protected in different ways in order to ensure resistance to corrosive sludge and substances.

DELKOR Overhead Filter Press (FP OH) - Overhead Beam Technology

This heavy-duty machine is best suited to high-volume applications where one requires a reliable filter in which many plates can be installed. This is the case, for example, for tailings dewatering applications, where we have successfully delivered a number of such machines for various tailings dewatering processes - from gold to iron ore.

Main technical features:

Plate size:                                From 1,000 x 1,000 mm to 2,500 x 2,500 mm
Number of chambers:   Up to 215 plates
Operating pressure: Up to 25 bar
Opening: Fully automatic – one-by-one

DELKOR Sidebar Filter Press (FP SB) - Sidebar Technology

The sidebar technology lends itself well to smaller slurry quantities where a cost-effective machine is required or for very special applications with long filtration times. This is the case, for example, for the treatment of lithium hydroxide and copper concentrates.

Main technical features:

Plate size: From 630 x 630 mm to 1,500 x 1,500 mm
Number of chambers:           Up to 120 plates
Operating pressure: Up to 15 bar
Opening: Manual or fully automatic – one-by-one, at once or batch

Optional Features

We also provide a range of optional features that can further enhance the capabilities of your machine, ensuring that it caters exactly to your specific requirements.

Your local DELKOR specialist can assist you in explaining some of the merits of these features:

Cloth washing:   

High pressure or low pressure. Both systems are available on all machines.

Cloth shaking:  

Shaking of filtration cloths at the end of each cycle for an improved removal of solids. Available on sidebar machines.

Drip trays:

Collection of drip water from cloth washing – improving environmental sustainability!

Smoke hoods:

Necessary when filtering toxic substances. In this case, the filter press is fully enclosed and does not permit the escape of harmful smoke.

Automatic end of filtration:                                  

A variety of different systems and sensors can be employed to detect the end of filtration (flow meter, pressure transducers, load cells etc.). Your DELKOR specialist will be able to determine the best suited to your application.

Sludge feeding pumps:

Sludge can be fed through a number of different pumping technologies. Your DELKOR specialist will select the most appropriate, taking into consideration the type of sludge, the working environment and the filtration process.


Our machines can be completely automated with PLC programs featuring remote control, remote diagnostic and/or maintenance.

Cake handling:

DELKOR, together with TAKRAF, can offer a wide range of crushing/cake breaker and conveying solutions in order to handle the solid cake ejected from the filter press.

Complete solutions for liquid/solid separation

TAKRAF, together with DELKOR, boasts a wide portfolio of products that enable us to provide complete turnkey solutions and equipment for tailings, minerals and soil processing.

    DELKOR FP OH for gold tailings dewatering in Uzbekistan

    3 x DELKOR FP OH filter presses as part of the gold mine processing plant’s gold tailings dewatering system. Each machine features mixed membrane filter plates together with a high-pressure cloth-washing robot and boasts a processing capacity of ~120 m3/h gold tailing sludge (~71 t/h of dry solids). The supply also included various ancillary equipment, including: belt conveyors for cakes discharged from the filter press (each machine is equipped with a cake breaker), pumping skids for membrane inflation, filter cake washing pumps and high-pressure cloth washing pumps. The entire scope of supply, including the slurry feed pumps, is fully controlled and managed by state-of-the-art software. Within this system, filter cakes are washed inside the filter with process water in order to remove any unwanted residual cyanides. The process designed for this application also includes cake squeezing (with pressurized water) and cake air blowing in order to achieve lower moisture levels within the final product.
