INNOVATIVE - POWERFUL - EFFICIENT Alonly as an accessory for BestWater water filter systems. (When using a system with an integrated pump, the internal pressure pump must be decommissioned). The BestWater pressure pump is distinguished by its compact design, easy installation and striking appearance. It can be connected to any molecular filtration system except direct-flow systems. No tools are required for installation, making the pump very easy to install. The pump is used when line pressure is low, below 3.0 bar, for maximum efficiency. The current pressure is clearly displayed on the pressure gauge. Two LEDs next to the pressure gauge provide information on the operating status of the pressure pump and indicate that the pressure tank is full. When the pressure pump is operating, the LED lights red. When the pressure tank is filled with permeate, the LED lights green.
