High-Pressure Filter Press Centrifugal Slurry Pumps

Filter Press Pumps: Precision Engineering for High-Pressure Slurry Feeding

Industrial Working Principle: High-Pressure Slurry Filtration

Filter press systems are high-performance industrial units designed to separate solids from liquids in high-density suspensions under extreme pressurized conditions. The overall efficiency and throughput of the filtration cycle are directly dependent on the reliability of the centrifugal slurry feed pump, which must maintain consistent pressure to overcome the increasing resistance of the filter media as the solid "cake" builds up within the chambers.

The process utilizes a series of chamber plates lined with specialized filter cloth. As the abrasive sludge is forced into these chambers by the high-head feed pump, solid particles are retained while the liquid filtrate is discharged under pressure. Investa’s filter press pumps are manufactured using our signature lost wax investment casting process, ensuring the structural integrity and abrasion resistance required to withstand heavy-duty continuous duty cycles in the chemical, mining, and starch processing industries.

Dynamic Sealing Arrangement

Dynamic Sealing Arrangement

Applications

  • Acidic Slurries
  • Effluent Waste
  • Pigment Manufacturing
  • Mining
  • Urban or Industrial sludge Dewatering
  • Other Chemical and Pharmaceutical Applications

Properties & Advantages

  • Also Known as Dynamic Sealing Arrangements
  • No seal water required.
  • Can pump up to 50 to 60% slurry and solid handling without much leakages which is there in normal gland pack pumps.
  • Due to less leakage the expensive product loss is much lesser as compared to normal gland packed pumps.
  • It comes with a very specialized Non-Asbestos Gland Packing/Grafoil Packing for High Temperature or can also accommodate Single Mechanical Seal.
  • No maintenance required as no slurry mechanical seals are used.
  • Can be operated on 1440 as well as 2900 rpm.
  • Rotating parts can be provided in CD4MCu material for abrasive slurry.
