Description
-Centrifugal pumps with vertical shaft, split body, diffuser, multistage, closed impeller.
-8 models from DN 32 to DN 150 discharge flange diameter.
-Suction flanges according to EN 1092 – 2 / PN 16 and discharge flanges to EN 1092 – 2 / PN 40 (PN 63). (flanges in pumps with stainless steel body material according to EN 1092-1 standard pressure class.)
-ARS-D and ARS-DY pumps are used with high efficiency electric motors according to IEC size.
-Pump and motor shafts are connected to each other with rigid coupling.
-All impellers are balanced dynamically or statically in accordance with ISO 1940 class 6.3.
-Axial force is balanced by impeller balancing holes system.
-The direction of rotation is counterclockwise when viewed from the motor side.
-In ARS-D and ARS-DY type pumps, “grease lubricated” bearings are used as standard. The plain bearings used on the underside of the pumps are lubricated with the pressed liquid.
