GENERAL INFORMATION

The Multiquip Model ST41230/ST41460 and ST61230/
ST61460 submersible pumps are designed to pump
water. These pumps work best when faced with high head
applications where you need an appreciable flow.
The pumping of flammable, toxic, corrosive, abrasive
liquids is strictly forbidden. These pumps are best suited
for clear water applications where maximum size of solids
(debris) does not exceed 0.6-inches (15.2 mm).
These pumps have a chrome steel body that is very durable
and able to withstand rough handling. The ST41230/
ST41460 comes with a 4-inch NPT threads for standard
hose connections, while the ST61230/ST61460 comes
with a 6-inch NPT threads for standard hose connections.
The pumps are designed with an industrial mechanical
seal. This seal assembly prevents the water that is being
pumped from entering the bearing housing of the pump
or simply the area between the motor face and the volute
where the shaft passes through. This seal assembly is oil
bathed for maximum lubrication and operational longevity.
For unattended pumping operations and water level control,
a specially engineered Control Box is available. The Control
Box provides safeguards that protect the pump motor from
over/under voltage; as well as provide external mechanical
Float Switch operations. Multiquip highly recommends the
use of selected Control Boxes to provide protection to the
motor.
Reference the Serial Plate of the pump before applying
power. Ensure that the voltage, phase, and cycles
corresponds to the power that will be applied for operations.
Allowing incorrect electrical power will severely damage
the motor of the pump.
