FELUWA MULTISAFE® double hose-diaphragm pumps
for abrasive, aggressive and toxic media


In comparison to typical bladder-type accumulators, the FELUWA PULSATROL 900 with roller diaphragm accumulator offers a unique advantage: The nitrogen cushion is automatically and individually adapted to the operating conditions by means of the Pump Condition Guard SMART. The position of the roller diaphragm is detected by an inductive transmitter. Based on this position a coefficient of operating pressure and pre-compression can be calculated. By means of this index number the control unit is able to determine whether increase or decrease of the pre-compression and filling (V2) or bleeding (V1) of nitrogen is required. The FELUWA PULSATROL is, therefore, not sensitive to operating conditions which deviate from the design layout and allows for a reduction of the uniformity coefficient to less than 0.5 % (p to p).
