 Here the traveling valve is at top stroke position.

At the left is the pressure tap for measurement

 of pump discharge pressure.
 
 
 
 

This displays the standing valve inside with the

landing nipple at the bottom of the pump. The pressure taps

measure pump intake pressure and the pressure inside

 the pump.
