Marelli VS1 vertical, radially split case, submersible centrifugal process pump

The vertical suspended centrifugal pumps are designed for pumping fluids on heavy duty process applications.

The FG pump is fully compliant with API-610 11th Edition VS1 and ISO 13709 standards. The pump assembly is partially submerged so the pump does not need priming before operation.  The drive unit is located above ground level and is completely accessible.

The pump is composed of four components: bowl assembly, column, discharge head and drive unit.

  • Flows to 13,209 USgpm (3,000 m³/hr)
  • Heads to 1,150 ft (350 m)
  • Maximum Working Pressure 189 psi (13 bar)
  • Temperature Range -22 to 482°F (-30 to 250°C)
  • Pit Depths to 40 ft. (12m)
