Goulds Submersible Pump Specifications

Goulds is one of the best-known pump brands, having been manufactured for 150 years. Now owned by ITT, Goulds produces a wide range of pumps, including submersible pumps designed for residential wells and small-scale municipal water distribution. In this category alone, Goulds markets five separate lines, each of which includes a number of models at various horsepower ranges.

5G and 7G Standard Capacity Pumps

5G and 7G Standard Capacity pumps are designed for use in residential wells 4 inches and larger. Both models feature a 1-inch discharge connection and operate with a counter-clockwise rotation. The 5G can pump between 1.2 and 7.5 gallons per minute, with an optimal rate of 5 gallons per minute. The unit can generate between 1/2 and 1 1/2 horsepower.

GS Series Pumps

GS Series pumps feature a stainless steel motor adapter, which ensures a durable, accurate alignment of the motor and the rest of the pump mechanism, and longer-lasting engineered polymer bearings. Goulds markets six different basic models of the GS, each of which is available in at least six different configurations. All are suitable for 4-inch wells and larger, and feature 1 1/4-inch discharge connections. The models (the numbers of which indicate their optimal gallon-per-minute operation) are the 5GS, 7GS, 10GS, 13GS, 18GS and 25GS. The 5GS produces from 1/2 to 2 horsepower; the 25GS runs between 1 and 5 horsepower.

GS Xtreme Pumps

The GS Xtreme pumps are designed both for deep wells and wells in challenging environments. The casing joints at each end of the pump are welded for maximum durability. Goulds produces nine different models of GS Xtreme pumps, again numbered by their optimal gallon-per-minute rating: The 5, 7, 10, 18, 25, 33, 40, 55 and 75GS-CBM. All of the pumps fit a 4-inch well and require a 2-inch discharge connection. The largest model can pump a maximum of 100 gallons per minute and generates up to 10 horsepower. It can pump water up a well shaft of 620 feet and still maintain 40 gallons per minute.

GS High-Capacity

The GS High-Capacity line combines the lighter weight of the GS line with the high output of the Xtreme line. It is available with optimal gallons-per-minute specifications from 33 all the way up to 80. The 80GS has a maximum flow capability of as high as 120 gallons per minute, and generates up to 7 1/2 horsepower. While GS High-Capacity pumps can match Xtreme pumps in terms of flow rate, they can't pump water as high. The 80GS, for instance, can only maintain a 40 gallon per minute flow rate up to 100 feet.

Bruiser Pumps

Goulds makes four models of Bruiser pumps, all of which are designed to operate in wells with high amounts of sand and other abrasives in the water. The impellers are designed with flat wearing surfaces that can stand up to constant abrasion. The 5SB has a maximum pumping capacity of 7.5 gallons per minute and a maximum power rating of 1 horsepower. The 7SB pumps a maximum of 10 gallons per minute and generates a maximum of 1 horsepower. The 10SB can pump water at a rate of up to 16 gallons per minute and generates a maximum of 1 1/2 horsepower. The largest Bruiser pump, the 18SB, has a maximum pumping capacity of 28 gallons per minute and can generate up to 1 1/2 horsepower.
