Handling:

  1. The direction of the rotation of this pump is clockwise when viewed from the shaft side.
  2. Drain piping must be direct piping up to a point that is below the tank fluid level. Back pressure, due to pipe resistance, should not exceed 4.3 psi.
  3. When adjusting pressure, pressure is increased by clockwise rotation of the adjusting screw and decreased by counter-clockwise rotation. The graph in Table 1 provides general guidelines for the relationship between the rotation angle of the flow rate, adjusting screw, and no load discharge rate.
