The filter press is an apparatus which either reduces the volume of products or filters solutions. Its operating cycle comprises two essential phases that are directly related to the upstream pumping solution – filling followed by maintenance of pressure at the end of the cycle.

The system selected must comply with certain requirements, such as guaranteed filling with a high flow-rate for better control of cycle time, verification of flow-rate during the pressure maintenance phase to provide better filtration quality or maintenance of the minimum desired flow-rate at the end of cycle for a better filter cake quality.

The PCM Series 1 pumps, derived from the company’s Moineau line, ensure filter press feeding while guaranteeing optimum operation throughout the pressure maintenance cycle. The filter press feed system proposed by PCM is suitable for all models – platen filter press, membrane platen filter press and dual feed filter press.

The use of one pump is well suited to for small filter presses. The pump can be used to carry out the entire cycle, from high flow-rate filling up to the end of the pressure maintenance phase with a minimum flow-rate.

The use of two pumps is designed for large filter presses where the filling flow-rate is higher, in order to guarantee reduced cycle time.
