  • The PT-"x"00 is a flux pressure feed tank system for pressure feeding flux to a flux hopper or weldinf torch.
  • Many tank sizes available, ie. 100 lb., 300 lb., 600 lb., or larger.
  • PT-3 (60 pound tank)
  • PT-100 (100 pound tank)
  • PT-300 (300 pound tank)
  • PT-600 (600 pound tank)
  • Electronic low or high flux level sensor is an option available for all size pressure tanks.
  • HPT-"x"00 Heated Flux Pressure Feed Tank. Same as above but is heated to 250 degrees F (121 degress C), adjustable.
  • All pressure tanks manufactured with an internal flux cone. This allows complete draining of all flux out of tank. There is no stagnant area in the tank from which flux will not flow out of tank.

  • The LPFR-3000 flux recovery system (less the tank) mounts directly to the pressurized flus feed tank.
  • Screws on the tank in place of the pressure cap.
  • Recovers all unfused flux and transfers flux to presure tank via a butterfly valve and geared hand-wheel opener.
  • Approximately 200 lb. capacity.
  • Requires a "Mighty-Mac" vacuum to provide vacuum power.
  • Option: MAGSEP-100 magnetic separator.
  • HLPFR-3000 is the same as the LPFR-3000 except it is heated under continuous control upto 250 degrees F (122 degrees C).
  • Manufactured with an internal flux cone. This allows complete draining of all flux out of tank. There is no stagnant area in the tank from which flux will not flow out of tank.

  • Recovers flux back to flux separation hopper; recovered flux is then pressure-fed to torch or welding equipment hopper.
  • Requires a "Mighty-Mac" vacuum to provide vacuum power.
  • Approximately 200 lb. capacity.
  • Option: MAGSEP-100 magnetic separator.
  • Optional electronic high or low flux level sensor is available to sense flux level of pressure tank or hopper. A loud audible alarm and flashing red light on control panel will signal operator.
  • HPFR-3000 is the same as the PFR-3000 except it is heated under continuous control upto 250 degrees F (122 degrees C).

  • The PFR-3000-300 is a 300 pound capacity pressure feed and recovery system.
  • Recovers flux back to flux separation hopper; recovered flux is then pressure-fed to torch or welding equipment hopper.
  • Approximately 300 lb. capacity for the pressure tank and 300 lb. capacity for the separator.
  • Requires a "Mighty-Mac" vacuum to provide vacuum power.
  • Option: MAGSEP-100 magnetic separator.
  • Optional Electronic Flux Level Sensor. A high or low flux level sensor is available to sense flux level of pressure tank or hopper. A loud audible alarm and flashing red light on control panel will signal operator.
  • HPFR-3000-300 is the same as the
    PFR-3000-300 except it is heated under continuous control upto 250 degrees F (122 degrees C).

PFRHAMX-3000 (heated)
HPF-3000/D
  • The PFRHAMX-3000 is a heated (control up to 250 degrees F {121 degrees C}) flux hopper/separator and pressure feed system.
  • Top hopper has two 50 pound capacity sections, one for recovered flux and one for new flux.
  • Flux from both sections mix together at a preset ratio as the flux is transferred into the the pressure tank.
  • Each section features a high and low level sight window.
  • The PFRHAMX-3000 is very useful for sub-arc welding when code requires a specific percentage of new flux to be mixed with recovered flux.
  • Option: MAGSEP-3 for optional magnetic separator.
  • Optional Electronic Flux Level Sensor. A high or low flux level sensor is available to sense flux level of pressure tank or hopper. A loud audible alarm and flashing red light on control panel will signal operator.
  • Manufactured with an internal flux cone. This allows complete draining of all flux out of tank. There is no stagnant area in the tank from which flux will not flow out of tank.

  • Heated pressure feed system with air dryer for submerged arc flux.
  • Heats from 250 degrees F (121 degrees C) to 400 degress F (204 degrees C) adjustable range.
  • Refrigerated air dryer for automatically pressure feeding flux to a flux hopper or welding torch.
  • Incoming shop air first passes through an oil and water trap, then a micron filter, and then through a refrigerated air dryer, before finally pressurizing the flux tank with very clean dry air.
  • The HPF-3000/D minimizes the effects of hydrogen assisted cracking due to moisture in the flux.
