SPL & DPL Filter Element – Hydraulic Lubrication Systems for Marine Diesel Engines

SPL & DPL filter element is a double cylinder filter element used in high viscosity melt filtration units. It is made of stainless steel sintered felt and stainless steel sintered mesh, which can easily remove hard impurities and coagulation. Among them, SPL & DPL filter elements can be reused and cleaned many times, which is economical and environmentally friendly.

SPL & DPL filter elements are mainly used for oil filtration in filter presses, filtration of oil systems in ships, diesel engines, and other equipment, and filtration of impurities in textile stocks in the chemical fiber industry on the front side of spinning nozzles of various types for the textile use of synthetic and man-made fibers and under other similar conditions. In these application scenarios, SPL & DPL filter elements can effectively filter out impurities and particles in the oil to protect the regular operation of the equipment. For applications in the textile industry, SPL & DPL filter elements also improve the quality of textiles, ensuring that they are produced free of impurities and defects.

  • High temperature resistance: can withstand high temperature conditions to ensure the stability and performance of the filter.
  • Corrosion resistance: usually made of corrosion-resistant materials to ensure stability and durability for long-term use.
  • Higher precision: different hole sizes and filtration levels are available according to the requirements of specific applications to meet the needs of particle size and impurity removal.
  • Higher strength & abrasion resistance: high viscosity melting can cause greater pressure and friction on filter elements, SPL & DPL filter elements usually have higher strength and abrasion resistance to maintain their filtration efficiency and life.


  • Size: It can be customized according to the requirements of filtration equipment.
  • Hole size: It determines the range of particle size it filters and is usually specified in microns (μm), such as 10 μm, 50 μm, 100 μm, etc.
  • Material: It can be made of a variety of materials, such as stainless steel, ceramic, etc. The choice of material depends on the temperature, chemical properties, and corrosion resistance requirements of the application.
  • Filtration level: It indicates its filtration efficiency and the size of particles it can remove. Common filtration levels include coarse, medium, and fine filtration.
