Modular design Flygt Multistage pumps utilize a modular design concept which maximizes component interchangeability. As such, multiple design configurations can be engineered to meet customer requirements without compromise to reduce spare part inventories. The entire performance range is covered by 7 mechanical sizes that hold 9 different hydraulics. Size Discharge connection Suction connection Capacity Capacity DNd (mm) DNs (mm) Q (m 3 /h) Q (m 3 /h) 50 Hz 60 Hz 84 . 80 100 120 140 104 . 100 125 170 200 124 . 125 150 250 300 154 . 150 200 420 500 204 . 200 250 660 790 253 . 250 300 800 – 254 . 250 300 980 – 303 . 300 400 1200 – 304 . 300 400 1400 – Hydraulics Closed radial type impellers designed for casing wear ring on both sides. Axial thrust minimized by balance holes for minimum bearing loads and a maximum bearing life. Size 84-154 P: on piece design for diffusor and casing. Size 204-304 P: two piece design for diffusor and casing. Balanced radial forces, minimum shaft deflection, minimum vibration. Heavy duty design for long term operation in industrial applications. All design versions acc. to ISO 5199 / EN 25199. ISO 9001 certification guarantees high quality standards and reliability of our products. 3
