Filter-press pumps are highly effective and often used for many applications that require solids, slurries or sludges to be separated from liquids. They are common in wastewater treatment, chemical processing, and various other industries.
It&#;s easy to understand why a filter-press pump would be recommended for this type of processing, but there are numerous factors you will need to consider when selecting the right filter-press pump for your specific application.
Cortech Engineering has put together this list of factors to consider when choosing the right filter-press pump:

Most filter-press pumps operate between 8 and 15 bar and will need to distribute the pressure evenly for the best results. You will want to have a pump that can handle your particular separation process and provide the consistent pressure that is required.
In order to operate a filter-press pump, different systems of displacement pumps are commonly used in conjunction to build the amount of pressure needed. Depending on the size of your plant and the processing that needs to be done, it&#;s important to have the right overall system designed.
The hose-diaphragm piston pump is one type of filter-press pump that has simple electrical operations while generating strong pulsation. However, it will require constant lubrication which can make installation/maintenance costs quite high.
AODD pumps are probably the most commonly used pumps for filter-press applications. They are resistant to dry running and require little maintenance because they are self-priming, self-regulating and highly compact.
If you are using an AODD pump for filter-press applications, it&#;s important to understand certain variants. Some systems will use one of the two diaphragms to generate the necessary additional pressure, but it leads to high pulsation, low feed rates, and high air requirements. An alternative is to use an internal pressure conversion. The set-up is more complex but very effective for demanding operations that seek performance and durability.
Most experts would agree that AODD pumps are the best option for filter-press operations, but there are still many factors and configurations to consider.

Achieving peak efficiency in solid-liquid separation
In industrial processes across diverse sectors, achieving efficient solid-liquid separation is paramount. Filter presses play a critical role in this task, but their effectiveness hinges on a key component: the filter press pump.
Filter press pumps function as the heart of any filter press system. These positive displacement pumps are engineered to deliver a consistent, high-pressure flow of slurry (a mixture of liquid and solids) into the press. This crucial pressure ensures efficient separation of the liquid phase from the solids, forming a solid cake within the filter press chambers.
Filter press pumps are instrumental in a wide range of industries, including:
&#; Chemical processing
&#; Pharmaceutical production
&#; Mining and mineral processing
&#; Wastewater treatment
Addressing limitations of traditional filter press pumps
While traditional filter press pumps play a vital role, they often present limitations that can hinder operational efficiency:
&#; Peristaltic pumps: These pumps offer limited flow rates and require frequent tube replacements due to wear.
&#; AODD pumps: Reliant on compressed air, AODD pumps can be susceptible to pressure limitations and incur high energy costs.
&#; Centrifugal pumps: Prone to leakage and energy-intensive, centrifugal pumps can experience fluctuating efficiency due to backpressure variations during cake formation.

These limitations can manifest as real-world challenges for your operation, including:
&#; Frequent leakages: Leaks necessitate downtime and ongoing maintenance costs associated with part replacements.
&#; Reduced pump lifespan: Short pump lifespans necessitate frequent replacements, impacting production continuity.
&#; Extended batch processing times: Inefficient pumping can lead to longer batch times and decreased overall throughput.
&#; High energy consumption: Compressed air-powered pumps can significantly inflate energy bills.
&#; Elevated maintenance requirements: Diaphragm failures and wear on components in AODD and progressive cavity pumps can necessitate frequent maintenance interventions.
