Pumps and valves, opened up

Centrifugal pumps and solenoid, check and relief valves cut open and explained part by part, so you can follow the flow from impeller to seal.

How a Centrifugal Pump Works

Impeller and volute flinging fluid outward to build pressure and flow.

How a Solenoid Valve Works

A coil-driven plunger opening and closing a fluid port on command.

How a Check Valve Works

A one-way flap or ball that lets flow pass but stops it returning.

How a Pressure Relief Valve Works

A spring-loaded disc that opens only when pressure gets too high.

Bubbles forming and collapsing on an impeller as local pressure drops.
