electromagnetic pump
LowTechnical/Scientific
Definition
Meaning
A device that moves fluid (typically a liquid metal) using electromagnetic forces, without moving mechanical parts.
A specialized pump used primarily in industrial and nuclear engineering to circulate conductive fluids, such as liquid sodium or molten metal alloys, by applying magnetic fields to generate flow pressure.
Linguistics
Semantic Notes
A highly specific compound noun referring to a piece of industrial machinery. The meaning is compositional but the concept is domain-specific.

Core term in specific engineering disciplines (nuclear, advanced metallurgy).
Examples
By Part of Speech
verb
British English
- The system is designed to electromagnetic-pump the coolant. (highly technical, rare)
American English
- The loop electromagnetically pumps the liquid metal. (adverb use more common)
adverb
British English
- The fluid is pumped electromagnetically.
American English
- The metal circulates electromagnetically.
adjective
British English
- The electromagnetic-pump design is crucial for safety.
American English
- The electromagnetic pump system requires no moving seals.
Examples
By CEFR Level
- (Not applicable for A2 level.)
- Some advanced machines use an electromagnetic pump.
- The reactor's secondary loop relies on an electromagnetic pump to move the liquid sodium.
- Unlike mechanical pumps, electromagnetic pumps have no moving parts in contact with the often-corrosive molten metal, thereby significantly reducing maintenance and failure risks.
Learning
Memory Aids
Mnemonic
Think: ELECTRICity creates MAGNETic force to PUMP metal.
Conceptual Metaphor
An invisible hand pushing liquid metal (force without physical contact).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation of components; 'electromagnetic' is one word in English, not two.
- The Russian term 'электромагнитный насос' is a direct calque, but the English term is highly specific.
Common Mistakes
- Using 'electric pump' (incorrect, implies an electric motor driving a mechanical pump).
- Pluralizing 'electromagnetic' incorrectly ('electromagnetics pump').

FAQ
Frequently Asked Questions
Only electrically conductive fluids, primarily liquid metals like sodium, potassium, or lead-bismuth alloys.
Mostly in nuclear reactors (especially fast breeders), in some metal casting industries, and in certain space propulsion systems.
No, because pure water is not a good electrical conductor. The principle requires a conductive fluid.
Two main types: conduction pumps (using direct current) and induction pumps (using alternating current), with induction pumps being more common for large-scale applications.
