PD Bag Lifting Upper Discharge Plate Centrifuge 1000mm Drum 140L 11kW 316L Steel

For products where the cake is the valuable component rather than waste, the PD series provides optimal handling. A shaped filter bag contains the solids, and upon completion, the entire bag is lifted out, preserving the cake's form. No blade contact ensures minimal fines and reduced loss for delicate crystals and high-value intermediates.

• Cake exits the machine intact, preserving crystal shape and particle size
• Single-lift unloading replaces scraping, reducing labor per batch
• Bag-to-drum seal contains fine solids within the basket during spinning
• Bag replacement enables filtration medium changes for product adaptability

The filter bag seats within the perforated drum. After feed introduction and drum spin-up, liquid passes through the cake and bag while solids accumulate inside the bag. Continuous bag support prevents cake disturbance. Following washing and dewatering, the drive stops, the loaded bag is hoisted out, and a fresh bag is positioned for the next batch.

• Rectangular plate base with elastic dampers for vibration control
• Vertical open-hole drum lined with filter bag as filtration medium
• Belt, VFD, or direct top drive options for required speed curves
• Shell on plate base with hinged lid for access and washdown
• Hoist system for lifting loaded bags clear of the basket

Ideal for high-value, fragile, or crystalline solids requiring particle shape preservation, including pharmaceutical APIs, fine chemical intermediates, specialty crystals, and selected food additives.

The cake remains in the filter bag; after dewatering, the entire bag is lifted out and emptied directly, maintaining cake integrity.

Scrapers cut and break the cake, while bag lifting eliminates blade contact, protecting fragile crystals and high-value products.

Yes. Single-lift removal of the entire cake is significantly faster than manual removal and reduces labor requirements per batch.

Yes. Washing and dewatering occur before bag removal.
