Submersible versus immersible


New member
A question from a Flow reader for the forum's feedback.

What is the difference between submersible and immersible pumps?

Can any anyone offer an explanation, please?

Submersible pumps have a sealed motor and pump assembly that can be totally submerged. Often used in water and waste water applications.

Immersible pumps have an extended shaft so that a standard electric motor is mounted above the liquid level with the pump immersed below. This type of pump is usually used for more aggressive liquids such as fume scrubber and chemical plating applications.
