Closing your manual hydraulic filter press

  1. Make sure the valve is open (handle down) and your starting pressure is 0 PSI
  2. Push the follower as far forward as it will go to make room for the hydraulic cylinder.
  3. Flip the cylinder to the clamp position (down)
  4. Make sure your pump handle is unlocked!
  5. Turn the pressure knob toward you
  6. Begin pumping to build pressure
  7. Pump until you reach the required closing pressure (this should be indicated on your gauge, if it isn’t, check your IOM manual for the appropriate closing pressure for your size press). Get as close to the pressure as possible, under pumping will cause a mess and over pumping will fatigue your equipment.
  8. Lock handle in place and close the valve (up)

    I’m having major problems with producing a dry cake. I pressure washed the cloths very well and it still produced a wet cake. What are the proper feed settings on a J-press. Please help. Trying to do a good job with no training.
