The Xylem Flojet AD4/90 multi-chamber diaphragm positive displacement pump is designed for transfer, demand/delivery, filtration, high flow booster, carbonation, beverage dispense and continuous reverse osmosis applications. Its maximum flow rate is 3L/min. New multi-chamber technology with patented valve design overcomes vibration and hydraulic pulsation.
AD4/90 continues to running in closed valve conditions liquid being recirculated via an internal bypass valve. AD500 ceases to running in closed valve conditions as it is fitted with a pressure switch
