Certified Service Training
What is a Submersible Pump
A submersible pump is typically a bottom suction, single stage centrifugal pump directly mounted on the shaft of a submersible motor
Motors can be electric, hydraulic or pneumatic
Certified Service Training
Where are they used ?
Anywhere water is and needs to be removed
Sand and Gravel Pits
Quarries
Dewatering well applications
Manhole dewatering
Coffer dams
Excavations
Construction sites ( all phases)
Certified Service Training
Who uses Submersible Pumps
General contractors
Municipalities
Utilities
Landscapers
Rental stores
Certified Service Training
AdvantagesNo suction hose or suction lift to calculate
Instant priming
High discharge head or high flow
Little attention required
Small investment for large capacity
Few parts, low repair & service costs
Runs dry for a short time
External power source required
Lower volume compared to trash pumps
Must be pulled out for inspection
Small solid size capacity
Why use a Submersible Pump
Disadvantages
Certified Service Training
When to use a Submersible Pump
Anywhere pumping head requirements exceed that of a trash pump
Environments where an internal combustion engine is not desired or allowed
Certified Service Training
P = Pump
S = Submersible
A = Automatic
2, 3, 4 = Discharge port size in inches
400-1100 = motor wattage
last digit = Phase either 0 (1Ø) or 3 (3 Ø)
HH = High Head
HF = High Flow

Certified Service Training
Cable Gland compresses the cable boot a full 360°
Upper Chamber
Insures an area around the thermal expansion boot allowing it to expand freely without contacting the cast iron walls.
Thermal expansion cable boot.
Extends the bending radius of the power cable and prevents kinking at the entry point
Power Supply Cable5 HP & larger Pumps
To prevent wicking each conductor is stripped back exposing the copper conductor,then fed through a fiber conductor. Epoxy is then poured into the expansion boot

Another form of seal is the lip seal.
All three phase units have lip seals
Lip Seal
This stationary seal is mounted below the bottom of the mechanical seal faces.
The impeller hub rotates against the flexible lip of the lip seal.
