★ Description ★
Plunger move from bottom to top in virtue of fluid pressure from top tube. Top and bottom traveling valve close. When stroke begins oil flow through inflow valve as different pressure, then oil flow in barrel through standing valve
Down-stroke oil-fluid pressure drive traving-valve, oil-fluid flow in tube thongh inner hole from bottom of plunger to top of plunger.
