The Basics of Submersible Pump Operation

Electric submersible pumps are typically best used in deep groundwater. To provide the most impact on the job site, choosing the correct pump needs to be step one. There are three variations of these pumps:

 

dewatering pumps: pump fresh water with minimal folic, such as sand

slurry pumps: pump heavy mud

sewer pumps: handle everything in a sewer

If the operator chooses the incorrect variation, the pump will promptly fail, leading to an expensive mistake. This is not ideal and can create many problems, including: clogging the pump, snapping the shaft, breaking the impeller and wearing the webbing down.

 

Once the user selects the correct pump style per the application, they should determine the amount of flow needed for the job, any elevation change and the desired distance for moving the water.

 

To combat gravity resistance, determining elevation change allows the user to know what pump strength is necessary to complete the task. It is important to know both the suction elevation from the water to the eye of the impeller, in addition to the discharge elevation from the eye of the impeller to the water’s destination. By adding these two numbers, the user will have the sum total elevation (gravity resistance).

 

The distance determines if the line size should be increased to reduce friction loss because of resistance. Friction occurs in all pipes and hoses when liquid travels through them. Velocity of the water traveling through the pipe or hose, as well as overall distance of the pipe or hose to the delivery point, both impact friction.
