2.20.4 Central Bicarbonate and
Concentrate Supply (Option)
A canister or central supply can be selected via the bicarbonate and
concentrate supply connection BVA and KVA.
The flow pump FPE guarantees a continuous control of the desired dialysate
flow into the balance chambers.
The flow rate is determined by the filling time of the balance chamber. The flow
pump FPE is controlled via the predetermined volume of the chamber and a
continuous detection of the position of the membrane.
