ST2037, 47, 47B,38P, 40T SUB. PUMP — COMPONENTS
Figures 2 shows the location of the basic components, for the
ST2037, ST2047, ST2047B, ST2038P, and ST2040T
submersible pumps. Listed below is a brief explanation of each
component.
1. Strainer Base – This strainer base is made of electrocating
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 Nitorile
Rubber to minimizes wear and prolong service life.
3. Electric Motor – These submersible pumps utilize a 60
Hz, single-phase, 115 VAC, 1 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) or 50 ft. (15.2 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 shut down
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 Seal Oil – 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 Seal Oil 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.
