About

Sharpenn Technologies manufactures Horizontal Rotary Pressure Leaf Filters (HRPLF) for industries requiring continuous, high-volume filtration with automated operation. The HRPLF consists of a horizontal cylindrical vessel, dished on both ends, housing a nest of filter discs spaced apart on a single rotating shaft. Unlike static leaf filters, the rotating leaf assembly enables continuous filtration under positive or vacuum pressure with automated cake removal. Manufactured at our Thane facility in SS304, SS316, and Carbon Steel.

Working Principal

The HRPLF operates with circular filter discs mounted on a central rotating shaft inside a pressure-rated horizontal vessel. During filtration, the leaf assembly remains static while feed suspension is pumped through under pressure. Solids are retained on the discs while clear filtrate passes through the central manifold.

Once filtration is complete and cake has built up, the leaf assembly is rotated. The rotation creates centrifugal force that dislodges cake from disc surfaces, discharging it through the bottom of the vessel.

Seamless support from prototype development to full-scale production runs efficiently.

Key Features & Industry Applications

Key Features
