Submersible Pumps

Ideal for small capacity duties 80 GPM until 1,600 GPM and high head applications: 1,500 ft, however, in some cases some of this pumps can be used for capacities of 5,780 gpm using 2 and 4 pole motors (1760 y 3460 RPM).

Typical Operation

Submersible pumps may be operated and controlled in the same manner as any other type of turbine pump in similar applications. No special consideration peculiar to the submersible is generally necessary, with the exception of the motor starting equipment. The motor, being installed in the pumped fluid, may not be subjected to the same ambient temperature as the overload relays in the starter. It is usually best to use current sensing type overload relays under this condition rather than the thermal type.


The submersible pump is especially suited to deep well and booster service for industrial, commercial, and municipal water systems. The pump utilizes submersible motor coupled directly to the bowl assembly and is designed to operate completely submerged in the fluid being pumped.
Power is supplied to the motor by waterproof electrical cable. In deep well applications, the pump motor and the cable are suspended in the well by the riser pipe. Booster applications involve installing the unit in a steel suction barrel or horizontally in a pipeline. Since the entire unit is either enclosed or below the surface of the ground, there are several applications where the submersible pump has many advantages:

· Extremely deep wells where problems with shafting are likely to be encountered (such as in crooked wells).
· In installations where flooding would damage standard above ground motors.
· Applications such as booster pumps which require quiet operation.
· Installations where there is little or no floor space.
· Horizontal pipeline booster pumps placed directly in the pipeline where conditions require a minimum amount of excavation or use of land surface.
· Dewatering applications.

Material Components

· Surface Mounting Plate
It holds the weight of the suspended unit and incorporates an elbow or fitting connected to the discharge piping. The surface plate also provides a junction box for terminating the electrical cable for the pump motor.


· Riser Pipe
It connects the submersible pump to the surface plate. The pump discharges through this pipe to the surface. It may be several hundred feet long in a deep well application or a short connection piece in a booster pump.


· Electrical Cable
It extends from the top of the unit to the surface.


· Pump Bowl Assembly
It consists of single or multiple stages to meet exact system head requirement. A wide range of bowl sizes is available to meet system capacity requirements. Standard construction includes cast iron bowls with bronze impellers on a stainless steel pump shaft. A suction strainer is used to prevent foreign objects from entering the pump.


· Electric Motor
It is attached to the lower end of the bowl assembly, becoming an integral part of the submersible unit. The motor thrust bearing carries the thrust load of the pump.


· Suction Barrel
It may be utilized for booster service. Its size will depend on specific installation requirements. For high-pressure applications, the suction barrel is extended to accommodate additional bowls.
