HORIZONTAL DRILLING DUTY PUMP Discharge Hydrostatic Test Pressure PERFORMANCE RATINGS A lubrication system supplying oil at 50 psi, 12 gpm and 200 SUS (44cSt) minimum values is required. Oil cooling is recommended and may be required to maintain these values. For operation in the Yellow shaded area expendable part life decreases and excellent NPSH is required to prevent cavitation. Performance figures based on 100% volumetric efficiency and 90% mechanical efficiency. These figures are for use in directional drilling duty cycle. "This equals full rod load 33% of the time, 60% rod load 50% of the time and 25% rod load 17% of the time, for a total of 1456 hours per year.
