Smith & Loveless I-SERIES™ Immersible Pumps deliver peace of mind for end-users and owners where immersible protection is required or recommended. Available for new and retrofit applications in lift stations and wastewater treatment plant operations, these heavy-duty pumps can be immersed for up to three weeks in flooding conditions. I-SERIES™ Pumps retain the same great features of the S&L Non-Clog Wastewater Pump, including oversized bearings and stainless-steel pump shafts, bronze mechanical seals for superior heat dissipation, close tolerances that prevent recirculation and a keyed and tapered shaft for positive lock and easy impeller removal. The result is decades of highly efficient pumping. Designed to withstand 21 days at 30 feet (9.1 m) submergence.
