The line of Godwin Sub-Prime GSL electric submersible pumps is designed for large sludge or dewatering applications. The GSL30 and GSL35 models are capable of maximum flow rates from 205 to 220 gpm (12.9 to 13.9 l/sec.) and discharge heads to 59 feet (18 meters). Like the dewatering models in the Sub-Prime line, these submersible sludge pumps are suited to tough construction, mining and industrial applications. The design features a side discharge that handles solids up to 2" (50mm) in diameter and rugged construction for long life, including a cast chromium steel impeller and heavy duty polyurethane-lined volute. Other benefits include tandem mechanical seals for dry running and extra protection against leakage, and a dual voltage junction chamber (GSL35) for convenient changeover in the field.
