Don-Nan Sand Shield

Rubberized fins to seal the pump from sand and solids

Prevent stuck pump scenarios

The sand shield is a two-piece component that is placed directly below the rod guide near the top of an insert sucker rod pump.

The rubberized fins act as a barrier against solids that otherwise would fall back through the fluid on well shutdown and potentially create a scenario in which an expensive fishing job for the pump would be required.


  • Aids in preventing stuck pump scenarios
  • Reduces particulate collection near the hold-down


  • 1 1/4- to 2-in [31.75- to 50.8-mm] insert pump sizes
  • Pressure-molded, nitrile rubberized fins
  • Stainless steel and brass mandrel options
