Filter press feeding

Filter press feeding
  • SINGLE , DOUBLE AND TRIPLE STAGE FILTER PRESS FEED PUMPS

    • Pemo’s Filter Press Feed Pumps are specifically designed for this application and there is little direct competition in this market due to the wide variety of models developed for this purpose.

    • The main advantage of the Pemo Filter Press Pumps is the Side Suction on the Horizontal Design. The seal in this design only sees the feed pressure of the feed slurry instead of the high pressure from the discharge of the pump. This allows simple mechanical seal flushing systems to be used. The seal flush system is sealed so no water or sludge will leak during the flush cycle.

    • Pemo Filter Press Feed pumps are designed specifically for abrasive and/or corro- sive applications using a variety of materials such as rubber lining, Hardalloy PEMO (750-800 HB), Stainless Steel or Hastelloy.

    • Capacities when filling the filter press can reach 6613 GPM (1500 m3/h).

    • Final Pressure can exceed 294 psi (20 bar) for the Triple Stage and for some Double Stage Models, creating a much dryer cake than single stage pumps can provide.

    • Mechanical Seals are all Silica Carbide or Tungsten Carbide.

    • The bearings are all specifically designed for filter press applications and are oil lubricated.

    • Lubrication of the 2 mechanical seals can be done by use of clean water at 30 psi minimum pressure. It can also be done by use of glicole in a closed pressurized system.

    • Some PEMO filter press pumps can also be provided in Submersible or Vertical versions.

  • the VERSIONS with hARDALLOY CASINGS

    • Specifically designed for applications with coal slurry and where higher pressures are required.

    • Operate at higher temperatures and long cycle times.

    • Currently there is 1 model in the Single, Double and Triple stage version, and there are 3 models available in the Single and Double Stage versions.

    • Recommended primarily for highly abrasive sludges.

    • Model S-FP AO/AB/DC-B55 is the smaller Double and the only Triple Stage model, and it is highly recommended when lon- ger cycle times at high pressure are required. This is more cost effective than expensive positive displacement pumps.

    • Custom Designed Pumps for specific applications can also be provided.
