The SA400 is a high-pressure mud pump powered by a Tier 4i (EU Stage IIIB) or Tier 3 (EU Stage IIIA) engine. It features an engine-mounted lubrication pump to provide constant flow through the system at any pump speed. During drill rod makeup/breakout, a clutch with continuous duty throw-out bearing allows extended clutch disengagement and a suction inlet valve suspends charged flow.
