Sub-Prime electric submersible GSP model pumps are designed with single-phase motors to 6 horsepower and three-phase motors to 80 horsepower for large dewatering jobs that require high head or high volume. There are 22 models, ranging up to maximum flow rates of 5,000 gallons per minute and discharge heads to 375 feet. The company says a cast chromium steel impeller and heavy-duty, rubber-coated adjustable wear parts make the GSP Sub-Prime pumps rugged and durable.
