FA - Flow activated pump system

Flow activated technology - unbeatable reliability, comfort and security


Flow activated unloader technology is based on the traditional KEW systems – tried and tested over more than 35 years. The start and stop impulses for the motor are created by the movement of water – and not by a drop or increase in pump pressure.


This unique system offers several advantages, especially user comfort and safety, when the machine runs in by-pass mode:


 Hose is easier to move around and the absence of pressure offers a higher level of safety
 Increased lifetime: With the flow activated unloader, small leaks will not cause motor start-stops
 Easily serviced system with good access to key components
 Low pressure at the pump head

NOTE: on hot water machines with flow unloader, the break tank is no longer sufficient to comply fully with water by laws EN1717 – as a by-pass around the break tank is made for the startup flow. In this case, it is recommended to also use an approved BA valve.
