System One Htm ryjiiirirwj UD î^î) Industry Standard for Reliability ■ High-strength, low maintenance line of innovative
process pumps ■ Designed specifically for the toughest, most extreme environments ■ Sets the industry standard for high-quality and durability
Durability ■ Lowest shaft stiffness ratio (L3/D4) in the process industry: • Frame S - 46 (1.9) • Frame LD17 - 17 (.65) • Frame M - 19 (.87)
Exclusive Features ■ Designed around the seal and bearings where 90% of failures occur ■ Designed to maximize system reliability - stronger, more vibration-resistant
pump ■ Heavy-duty, solid, low deflection shaft prevents common vibration damage and greater stability at the seal area to improve seal life ■ Heavy-duty bearings offer greater i 9 P i. £ V,
•J «S» 34 load capacity and extend bearing life ■ Patented System One® Labyrinth Seals provide non-wearing lifetime protection for radial and thrust bearings
Heavy-Duty Construction ■ Heavy-duty shaft, bearings, seals and housing design means this
pump is built for reliability in the most extreme environments ■ Offers the widest window of operation off the BEP of any conventional centrifugal
