Features and Benefits

  • Split case design with lifting lugs simplifies maintenance by allowing access to the rotating element without disturbing the piping or driver

  • Low NPSH enclosed impellers provide high efficiency and optimum performance over a wide flow range

  • Most LR and LRV models feature double-suction impellers

  • The LLR incorporates back-to-back, single-suction impellers

  • Radial and thrust bearings are available with oil or grease lubrication

  • Designs include single row, deep groove ball bearings or duplex thrust ball bearings

  • Typical L10 bearing life is 100 000 hours

  • Heat-treated steel shaft limits deflection to 0.05 mm (0.002 in), prolonging seal life

  • Shaft sleeves are secured by external nuts and include O-rings to ensure reliable internal sealing

  • Mounting feet transmit pipe strain loads to the base and foundation, extending bearing life
