The Flow-Link™ series flow centers simplify installation on using Flow-Link™ double O-Ring fittings that eliminate the possibility of leaks that sometimes occur with threaded fittings. Front flush ports allow easy access during installation. Foam insulation on stops condensation, and the high impact polystyrene cabinet will not rust. Flow-Link™ flow centers are available with either die cast brass or composite valves. Flow-Link™ flow centers offer both constant speed and variable speed pump operations. All Bosch flow centers are fully assembled and leak tested. Bosch utilizes industry standard Grundfos circulators.
The cabinets are designed to allow pump heads to be rotated, or for upgrading/downgrading (i.e. adding/removing a pump).
Pressurized flow centers with more than one pump are assembled so that when installed, the pumps are in series. This can be thought of as a “push-pull” pumping arrangement.
