20hp Submersible Water Pump

20HP Submersible Motor

20HP water submersible motor is water filled 3 Phase induction motor that is designed for driving water submersible pump in reliable quality. The APK motor is water proof design. All conductors of squirrel-cage of the rotor are made of pure copper bars. And the stator winding is using water proof wires. The thrust bearing is made from special plastic or graphite and thrusts lubricated and cooled by water. This ensured durable operation with heavy load.

1. How to circulate head means (TDH):

To calculate Total Dynamic Head, also known as TDH, we need to calculate three things:

A) The Vertical Rise.

B) The Friction Losses of all the pipe and components the liquid encounters on the discharge of the pump.

C) After calculating both, add them together to calculate TDH.

Water Submersible Pump Applications:

1. Ground underground water pumping

2. Farmland agricultural irrigation system

3. Sea water, shipyard, offshore, boat ship, mariculture, floating dock, salt water

4. Drawing water from deep well or borehole

5. Pumping water from lake, river, vessel, tank, reservoir

6. Fountain projects: horizontal installed
