Filter press pumps

Filter Cake 

Filter press pumps are specialist pumps designed to fill a filter press with slurry and achieve high pressure for a good quality cake. Although set-ups differ from site to site, they are usually sited on the ground close to the filter press and are piped up into the filter press.

Centrifugal slurry pumps are good for the higher flows needed when filling filter presses, but struggle to maintain the higher pressure required when pressing. Progressive cavity pumps meanwhile are great for the high pressure but are unable to achieve high flows.

Most sites that operate a filter press will adopt a compromise solution, either using a centrifugal double-stage slurry pump or a ram pump to undertake both the filling and pressing. This however may not be your best option. 

A solution operated by Atlantic Pumps provides the advantages of both types of pumps without any compromise. Furthermore, by spending slightly more on the initial outlay, you can make large savings in the long run. 

The filter press pump system offered by Atlantic Pumps differs to most set-ups because it comprises of two pumps: a centrifugal slurry pump and a positive displacement pump. A SlurryPro centrifugal pump will handle the bulk filling of the press while the positive displacement pump does the pressing. 

Neither pump in our two-pump set-up needs to be running continuously or pumping for longer than is necessary unlike the centrifugal double-stage slurry pump option. With the pumps operating for a reduced combined time therefore, a site can reduce its energy costs and save money. 

Centrifugal double-stage slurry pumps are also in near constant operation. As a result, they will often wear out quite quickly. As our own investigations have found, parts aren’t readily available and can be costly.

With the SlurryPro and positive displacement pump both operating for less time than the centrifugal double-stage slurry pump, wear to the parts in our set-up are greatly reduced. 

And when it does come to replacing components, parts for our filter pump press pumping system are available on very quick lead times with affordable maintenance costs.

In smaller applications and sites, such as laboratories a two-pump set-up wouldn’t be suitable. In such situations we would either recommend a SlurryPro centrifugal pump or LSM peristaltic pump - both proven performers in a wide variety of applications.
