Aurora Pump”s ANSI 3500 Series pumps are designed to perform in difficult industrial applications whether in the chemical, petrochemical, mining, pulp and paper, food processing or general industry. Industrial customers can choose between two models — the 3550 and the 3560. The ASME/ANSI B73.1M Model 3550 supports capacities up to 4,200 GPM and heads to 725 feet while performing in temperatures up to 343 C and pressures to 375 PSIG. The 3550 comes in three sizes of 3550-S, 3550-M/L and 3550-XL. These models were developed with standard features that withstand the most difficult applications and maximize the mean-time-between-failures (MTBF). The heavy-duty casing increases reliability, reduces maintenance effort, and allows for maximum life from the ANSI pump. Heavy-duty bearings on the 3550 were designed for maximum hydraulic loads with optional duplex (40°/40° angular contact) thrust bearings. Features that help prolong bearing life include an oversized shaft to reduce vibrations, labyrinth oil seals to prevent external contaminants, large capacity oil sump for cooler oil temperatures, and better heat transfer and a magnetic drain plug to remove particles. The fully open impeller is designed for harsh applications, including solids handling, stringy materials, abrasives and corrosives.

The ASME/ANSI B73.1M 3560 Model supports capacities up to 7,000 GPM and heads to 725 feet while withstanding temperatures of 343 C and pressures to 375 PSIG. The pumps are available in groups 1, 2 and 3 with standard features required to withstand the most difficult applications and maximize the mean-time-between-failures (MTBF). Standard features include lip-type oil seals, an oversized shaft, heavy duty bearings and casing for extended pump life, external impeller adjustment, large capacity oil sump, lubrication flexibility (oil flooded, oil mist or greased), a large sight glass for oil monitoring and a magnetic drain plug to remove particles. A fully open impeller is also available for tough applications, while an enclosed-impeller option is designed for enhanced performance. Positive sealing provides ease of maintenance and increased safety, and the engineered chambers in standard bore, large bore, and taper bore are designed to create the optimum seal environment. Sealing options are available to accommodate most fluid and temperature combinations.
