SA400 High Pressure Mud Pump

The SA400 is 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.

Features and benefits

  • A remote pendant control allows the operator to place control where it makes sense for them.
  • The SA400 features light shielding – each panel weighs less than 50 lb (22.8 kg) – making maintenance a one-person task.
  • A liner wash tank integrated into the machine’s design eliminates the need for extra water containers or electricity when running the pump.
  • See your Vermeer dealer for comprehensive service and genuine Vermeer replacement parts.
