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 and recirculation branches
- Incorporates control valve in recirculation with anti-cavitation system
