What to do if the delivery pressure of my Major 2400 LGP Farm Equipment centrifugal pump is too low?
- I
  Ivan DicksonJul 26, 2025
  If the delivery pressure isn't reaching working values, there are several potential causes. The impeller lugs might be worn or broken, requiring impeller replacement. The RPM could be too low; try increasing it to a maximum of 600 RPM. The tractor PTO may lack sufficient power, so increase the power. Also, the diameter of the outlet hole of the nozzle of the rotating jet may be too wide; in that case, decrease the diameter of the outlet hole.

  Adam CooperJul 31, 2025
  If sewage isn't exiting the delivery tube, first check for obstructions in the delivery tube and eliminate them. Next, ensure that the lever gate valve above the centrifugal pump is open. Finally, verify that the handle of the exhauster/compressor is positioned towards the left; if not, position the handle accordingly.
