BENEFITS

  • Increases energy efficiency by 1%
  • Reduces maintenance costs of the centrifugal pump
  • Increases plant availability
  • Economy in the initial investment of the motor operated pump (smaller pump; smaller motor; smaller skid)

ADVANTAGES

  • Eliminates the waste of energy added by the pump to the continuously recirculated fluid
  • Protects the centrifugal pump automatically against the inadvertent use at flow rates below the minimum recommended by the pump manufacturer
  • Allow the use of smaller motor-pump assembly

CHARACTERISTICS

  • Self-operated and compact, rotameter in the main flow drives the control valve in the recirculation
  • Incorporates check valve (non return) function in the main flow branch
  • Incorporates control valve in recirculation with anti-cavitation system

  • Sizes: 1’’ to 30’’
  • Pressure class: 150# to 600#
  • Construction standard: ASME B16.34
