ETF Flow-controlled Booster Silent Pump(No Rust)


  • Must Install ETF pump below the water tower, to boost water pressure downward. When using water,the pump will run automatically to increase water pressure and supply. When no using water, the pump will auto stop running.
  • Built-in microchip control. Automatic power off when no water is detected within 60 seconds, to avoid the motor being burn up.
  • Dual-voltage 110 / 220V design for 60Hz models, you can adjust the required voltage.
  • Low operation noise. The supply of water pressure is stable, and the water pressure will not change suddenly when taking a hot bath. The water temperature will not suddenly become cold or hot.
  • All-in-one design, compact size saves installation space.
  • The pump casing structure is made of reinforced plastic steel, and the wetted parts are not rust or create rust water. The motor shaft also will not get stuck easily due to leave unused for a long time.
  • Built-in thermal switch, mainly to avoid frequent ON/OFF or nonstop running which lead to outlet pipeline to burst out by water overheating.
  • If the pump is installed outdoors, it is recommended to install a cover for protection. It can protect electronic parts in the ETF series being damaged by heavy rain or direct sunlight which can extend the product life span.
