Diesel fire fighting pump
-Horizontal ring section, multistage, centrifugal pumps with closed impellers and di¬users in end suction design. -7 Models from DN 40 up to DN 150 discharge flange diameter. -Suction nozzle flanges conform to EN 1092 - 2 / PN 16 and discharge nozzle flanges conform to EN 1092 - 2 / PN 40 (PN 63) (For steel or stainless steel casing pumps, flanges comform to related pressure class ratings defined in EN 1092 - 1) -Discharge flange is on top for standard production, upon request di¬erent discharge flange positions can be applied. -All impellers are balanced dynamically or statically according to ISO 1940 class 6.3. -Axial thrust is balanced by impeller balancing holes system. -Direction of rotation is always counter clockwise viewed from drive end. That’s why these pumps can not be accouppled directly with diesel engines. -Bearings of ARS-U type pumps are grease lubricated. Sleeve bearing used in the suction side is lubricated by the pumping liquid.

Diesel fire fighting pump
-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 TS EN 1092 - 2 / PN 16 and discharge flanges to TS EN 1092 - 2 / PN 40 (PN 63). (flanges in pumps with stainless steel body material according to TS EN 1092-1 standard pressure class.) -ARS-DY 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 elastic 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-DY 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.
