The line of Godwin Sub-Prime GSP electric submersible pumps is designed for large dewatering applications. The GSP25 and GSP35 models are capable of maximum flow rates from 254 to 301 gpm (57.7 to 68.3 M3/hr.) and discharge heads to 61 feet (18.3M). Like the small dewatering and trash handling models in the Sub-Prime line, these large dewatering submersible pumps are suited to tough construction, mining and industrial applications. They feature a slim-line design ideal for fitting into confined spaces and rugged construction for long life, specifically a cast chromium steel impeller and heavy duty rubber coated adjustable wear parts. Other features and benefits include tandem mechanical seals for dry running and extra protection against leakage, and a dual voltage junction chamber for convenient changeover in the field.
