GS Series Submersible

Summary

Product Identification

This document covers specifications for the GS/GST Series (1.2 - 3.7KW) and RS/RST Series (0.5 - 1 HP) submersible pumps.

GS/GST Series Submersible Pumps

Application

• Available free-standing or guide rail mounted for fixed installation.
• Suitable for domestic and industrial applications requiring high heads or long distances, where standard submersible pumps or large bore discharge pipes are not feasible or economic.
• For process works handling wastewater with organic solids.
• Efficient disposal of sewage and farm waste to mains sewers or on-site treatment works.
• Used in package sewage stations and for portable sewage pumping.
• Most nuisance water drainage applications where organic solids are present.
• GST12(GS1200) and GST15(GS1500) models are supplied without a sensor.
