GENERAL INFORMATION
The Multiquip Model ST3020B1 and ST3020BCUL
submersible pumps are designed to pump water and
is used for the draining (dewatering) of well casings
construction sites, coffer dams, manholes, transformer
vaults and excavations.
It's slim design (only 6.7 inches in diameter) allows it to fit
easily inside 8-inch casings and eliminates the need for
larger, more costly casings. The pump is powered by a
2-HP, 230-volt, single-phase motor for easy starting with a
6,000-watt generator.
This rugged submersible pump is loaded with features
such as:
- automatically
shuts off the motor should it reach an unsafe operating
temperature.
- provides and
convenient and safe location to attach a lifting device.
- provides added safety
in the event the operator should try lifting the pump from
the electrical cord.
- provides easy
maintenance and lower repair costs.
- provides positive
lubrication if the pump should be left running dry. This
helps prevent damage in the event the pump is run dry
for short periods of time.
- for abrasion resistance
and extended life. The high-chrome ductile iron material
minimizes wear.
- simplifies maintenance
If the pump was used to pump water containing mud, silt,
use clean water to flush out the pump after each use.
allow the pump to run dry for an extended period
of time, as this will damage the pump. During maintenance,
dry running is permissible but only for a few seconds.
lift the pump by its electrical power cord. ALWAYS
lift the pump by its carrying handle or attach a rope to the
carrying handle.
A pump fully submerged in liquid will not freeze, unless
the liquid freezes. allow a partially submerged
pump to freeze. The expansion of water freezing in the
volute may crack the pump, causing expensive repairs. If
there is any danger of the pump being subjected to freezing
temperatures, Lift the pump from water and allow it to drain
thoroughly.
If the pump jams or the pump rotor locks for any reason,
disconnect the pump from the power source immediately.
Allowing the pump motor to cycle and under an
overload condition can burn out the motor.
When replacement of nuts and bolts is required, use only
recommended parts as referenced in the parts section of
this manual. This pump uses metric threads. use
English measurement threads.
