Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain pump types and how they work, help select, size and maintain pumps, address safety and efficiency, and separate other senses of pump.

A device that moves fluids, liquids, gases or slurries, by mechanical action, from positive displacement pumps such as piston, gear, rotary vane and diaphragm pumps to dynamic pumps such as centrifugal and axial pumps, including submersible pumps, pumpjacks and vacuum pumps; pumps are essential in water supply, industry, vehicles, medicine and the home, and the word also has other senses such as a type of shoe.

What it is for: Moving fluids.

It can be identify pump types and principles; select and size a pump; troubleshoot and maintain pumps; explain efficiency and safety.

Distinguishing features

Fluid moving machine

Two main principles

Wide range of sizes

Efficiency and safety critical

What it looks like

Machines with inlets, outlets, casings and a motor or drive.

How it is recognised

Moves fluid from inlet to outlet

Positive displacement or dynamic

A compressor mainly raises gas pressure
