Pump Components - MULTIQUIP ST2037F Operation And Parts Manual

Figure 2 shows the location of the basic components, for
the ST2037F and ST2040TF submersible pumps with a
float switch.
Listed below is a brief explanation of each component.
1. Strainer Base — This strainer base is made of
electrocoating 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
dewatering purposes, always place the strainer base
on a platform.
2. Volute/Impeller — Impellers are constructed of Nitorile
Rubber to minimize 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) AC power cable which is equipped with a
float switch. 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.

Components
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.
10. Float Switch — This float switch employs a micro-type
switch for the switching operation. Be certain that the
float switch cannot hang up or foul in its swing.
