Submersible pump - Wikipedia

A submersible pump (or sub pump, electric submersible pump (ESP)) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface.

Pump Starting Methods

Star-Delta Is an older method of starting motors (no longer frequently used in the UK) which allows for connection of the pump motor with reduced voltage (across the motor windings). This also reduces the torque by a factor of three. After a short period of time the delta configuration is then employed which makes the motor run normally.
