ST-2005 SERIES SUBMERSIBLE PUMPS — OPERATION & PARTS MANUAL — REV. #3 (09/21/04) — PAGE 11
ST-2005 SERIES SUB. PUMP — COMPONENTS
Figures 2 shows the location of the basic components, for the
ST-2005 series 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. DO NOT
pump large objects or debris with this pump. This pump is
for pumping water only. For de-watering purposes, always
place the strainer base on a platform.
2. Volute/Impeller – Impellers are constructed of high-chrome
ductile iron to minimizes wear and prolong service life.
3. Electric Motor – All 2005 series submersible pumps
utilizes a 60 Hz, single-phase, 115 VAC, 0.5 HP electric
motor. Consult with a
licensed electrician
before
connecting motor to a power source. Observe all city and
local safety codes.
4. Discharge Port – Connect a 2-inch hose to this port.
Remember to adequately support the discharge hose to
avoid stress on the pump.
5. AC Power Cable – This unit is supplied with a 25 ft. (7.6
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.
6. Carrying Handle – Always carry the submersible pump
by its handle. NEVER! carry the pump by its power cord.
Carrying or lifting the pump by the power cord, will cause
undue stress on the cord, and ultimately the cord will
become dislodged from the pump.
7. Thermal Overload Protection – This pump is equipped
with a thermal overload protection device that will shutdown
the motor in the event of high operating temperatures. The
motor will automatically restart once the temperature returns
to an acceptable operating temperature.
8. Mechanical Oil 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.
9. Mechanical Oil Seal Plug – Remove this plug to check
and add hydraulic oil (Shell 32 or equivalent) to the oil
cavity. This oil protects the mechanical seal. Oil cavity should
be full enough to cover seal spring.
