Figure 2 shows the location of the basic components, for
the submersible pumps. Listed below is a brief explanation
of each component.
1.
strainer base –
This strainer base is made of stainless
steel which is resistant to hardware corrosion. For
dewatering purposes, always place the strainer base
on a platform.
2.
mechanical seal –
This oil-filled seal provides
lubrication when running the pump dry.
never
run
the pump dry! Running the pump dry will cause severe
damage to the pump.
3.
electric motor –
These pumps use either a 230 VAC
or 460 VAC, 3Ø, 60 Hz electric motor. Reference
Table 1. for the electric motor for your model pump.
Consult with a licensed electrician before connecting
motor to a power source. Observe all city and local
safety codes.
4.
nameplate –
Provides vital electrical pump information.
Always read this tag before applying power to the pump.
5.
Discharge port –
Connect a 4-inch hose to this port
(NPT 4" threads). Remember to adequately support
the discharge hose to avoid stress on the pump.
6.
lifting Handle –
Attach a suitable lifting device to this
handle capable of lifting about 200 lbs. (91 kg)
never
lift the pump by its power cord.
7.
aC power Cable –
These pumps are supplied with a
33 ft. (10 meters) AC power cable. Always check the
cable for signs of wear.
never
use a defective power
cable. Replace the cable immediately if the cable is
worn or defective.
8.
power Cable Clamp –
Attaches power cable to pump
to prevent movement.
9.
impeller –
Impellers are constructed of chrome steel
to minimize wear and prolong service life.
10.
mechanical seal oil plug –
Remove this plug to
check and add ISO VG32 lubrication oil, Mobile DTE
24, turbine oil 90 or equivalent to the oil chamber. This
oil protects the mechanical seal. Oil chamber should
be full enough to cover seal spring.
11.
Discharge port –
Connect a 6-inch hose to this port
(NPT 6" threads). Remember to adequately support the
discharge hose to avoid stress on the pump.
12.
eye bolts –
Attach a suitable lifting device to this
handle capable of lifting about 300 lbs. (136 kg).
never
lift the pump by its power cord! Lifting the
pump by the power cord will cause undue stress on
the cord and ultimately the cord will become dislodged
from the pump
