What is the principle of submersible pump?
A submersible pump pushes water to the surface by converting rotary energy into kinetic energy into pressure energy. This is done by the water being pulled into the pump: first in the intake, where the rotation of the impeller pushes the water through the diffuser. From there, it goes to the surface.
What are stages in a submersible pump?
Submersible pumps can feature a single stage or multiple stages. Each stage consists of a motor in a casing, closed with mechanical seals to prevent leakage. The motor is connected to a cable that generates power to run the motor, and the casing extends to some sort of pipe or hose leading to the surface.
What are the two main components of a submersible pump?
The submersible pump system consists of both downhole and surface components. The main surface components are transformers, motor controllers, junction box and wellhead. The main downhole components are the motor, seal, pump and cable.
How many stages does a submersible pump have?
The motor used to drive the pump is typically a three-phase, squirrel cage induction motor, with a nameplate power rating in the range 7.5 kW to 560 kW (at 60 Hz).
How do you calculate submersible pump stage?
The submersible pump stage calculation tells you how many stages are required. You find it by dividing the total dynamic head (TDH) by the length of each stage. The TDH is the equal to the sum of the pumping level, head length, drop pipe friction loss and check value friction.
How do you calculate stages of a submersible pump?
What is 2 stage pump?
A two-stage pump has two suction impellers operating side by side. The operator must decide if he wants volume or more pressure by selecting a switch on the pump panel. The pump operator must be comfortable with a transfer valve and decide when to use volume versus pressure.
Do submersible pumps have check valves?
Check valves are designed to permit water to flow in one direction and are a requirement on all submersible pump installations. Some submersible pumps have check valves built into the unit and are suitable for operation without an external check valve, as long as the pump is not set too deeply.
How do you calculate submersible pump capacity?
Quick Formula
- Water horsepower = minimum power required to run water pump.
- TDH = Total Dynamic Head = Vertical distance liquid travels (in feet) + friction loss from pipe.
- Q = flow rate of liquid in gallons per minute.
- SG = specific gravity of liquid (this equals 1 if you are pumping water)
- Water horsepower =

What is the working principle of electric submersible pump?
Working principle. Electric submersible pumps are multistage centrifugal pumps operating in a vertical position. Liquids, accelerated by the impeller, lose their kinetic energy in the diffuser where a conversion of kinetic to pressure energy takes place. This is the main operational mechanism of radial and mixed flow pumps.
What is a hydro hydraulic submersible pump?
Hydraulic submersible pumps (HSP’s) use pressurised fluid from the surface to drive a hydraulic motor downhole, rather than an electric motor, and are used in heavy oil applications with heated water as the motive fluid. One style of submersible pump for industrial use.
What is the working principle of a liquid pump?
Liquids, accelerated by the impeller, lose their kinetic energy in the diffuser, where a conversion of kinetic to pressure energy takes place. This is the main operational mechanism of radial and mixed flow pumps.
How does a submersible septic tank pump work?
Submersible pumps are efficient for pumping out septic tanks. Fluid is transferred into hoses to storage tanks and taken to a treatment facility. The working principle of this pump simple as the single stage centrifugal pump.
