What's a turbine pump?

What's a turbine pump?

What's a turbine pump?

(OP)
I understand what's a "turbine" and a "pump" but never get what's a "turbine pump".

Don't these two words contradict if used together? My understanding in most basic terms is that,
a turbine converts motion from fluid to torque in a shaft
a pump converts torque in a shaft to motion in a fluid

Isn't the term "turbine pump" so vague. It could mean:
1. a pump serving for a turbine (eg. turbine feed pump in a turbine cycle, turbine lube oil pump, etc.)
2. a set with a turbine driving a pump. If referring in contrast to an electric-motor-driven pump, if a pump is instead being driven by a turbine, then the term "turbine pump" might be used instead of an "electric-motor pump"
More definitions could be made up.

Am I missing something?

RE: What's a turbine pump?

That seems to be more an academic question. As far as I remember turbine pumps are called "turbine" pumps because of the impeller shape and design which looks a bit like turbine vanes.

RE: What's a turbine pump?

Yes you are missing something, a Google search of "turbine pump" -- fully detailed with picture etc. If talking with anyone involved with pump equipment, turbine pump would normally be understood.
Normally turbine pump is a vertically stacked multi-stage pump as you will see in Google.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

RE: What's a turbine pump?

A turbine can do both things (convert flow to torque or torque to flow).

A water turbine is classically the former, a turbine pump the latter.

a simple google search for the two terms shows the difference.

A turbine pumps is what is sometimes called a vertical multi-stage pump e.g. http://www.spxflow.com/en/clydeunion-pumps/pd-sbwm...

Pumps are more typically thought of as torque to flow

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: What's a turbine pump?

You should usually see this as "vertical turbine pump."

RE: What's a turbine pump?

Pump nomenclature is not precise and terms are based on historical precedent and tradition. The term "centrifugal pump" is a generic term describing a basic pump. A turbine is a machine for producing continuous power in which a wheel or rotor, typically fitted with vanes, is made to revolve by a fast-moving flow of water, steam, gas, air, or other fluid.

As the pump industry developed, trade associations developed pump nomenclature. Pumps may be classified in many different ways. The Hydraulic Institute developed a nomenclature for pumps according to their design.



Turbines were invented much earlier than the invention of the turbine pump in the 1800's. The Francis Turbine was invented in 1848. It is an inward-flow reaction turbine that combines radial and axial flow concepts.

A turbine pump is a type of centrifugal pump.
