GENERAL INFORMATION
The Multiquip Model ST-4125D and ST-6125D submersible
pumps are designed to pump water. These pumps work best
when faced with high head applications where you need an
appreciable flow.
The ST-4125D and ST-6125D submersible pumps have dual
voltage, 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 ST-4125D
comes with NPT threads for standard hose connections while
the ST-6125D is equipped with 6-inch flange fittings.
The mechanical seal of these pumps operates within an oil-
filled chamber that provides positive lubrication. This helps
prevent damage in the event the pump is run dry for short periods
of time.
