GST Sub-Prime
The GST Sub-Prime line is a selection of portable, electric submersible pumps designed for trash laden applications. Standard side discharge and semi-vortex cast iron impeller enable these units to handle up to 1" (25mm) diameter solids. And the fully removable volute makes clean-out fast and easy. The GST Sub-Prime line offers flow rates to 75 gpm (4.75 l/sec) and maximum heads to 48 feet (14.6 meters). Units are available in 0.5 hp / 0.4 kW (GST05) and 1 hp / 0.75 kW (GST10) models. Need versatility? High performance and affordability combine to make the GST Sub-Prime ideal for use in general dewatering applications as well. For automatic applications, a piggy back single float switch can be supplied.

Pumping range based on operation in non-turbulent conditions. Actual range may vary due to temperature conditions and cord shape. Tether length increases variance of pumping range.
WARNING: Pumps are not designed for use in explosive atmosphere,
flammable environments or for pumping volatile liquids.
