The Pump is double acting (output in both directions).
When the Pump is going in the up direction the upper check close sand material is pumped out. The lower
checks open allowing the lower chamber to be filled. The primer checks help bring viscous material into the
chamber. In the down direction the upper check opens and the lower check closes allowing material to be
pumped out. The different diameters of the piston rod displace the material.
