ST4125G/ST6125G — GENERAL INFORMATION
The Multiquip Model ST4125G and ST6125G submersible
pumps are designed to pump water. These pumps work
best when faced with high head applications where you
need an appreciable fl ow.
Each pump has dual voltage capability, easily switched
between 230 and 460 volts.
These pumps have a heavy-duty cast iron body that is
very durable and able to withstand rough handling. The
ST4125G comes with a 4-inch NPT threads for standard
hose connections while the ST6125G is equipped with
6-inch fl ange fi tting.
The mechanical seal of these pumps operates within an
oil-fi lled chamber that provides positive lubrication. This
helps prevent damage in the event the pump is run dry for
short periods of time.
