Product Description
Well Down Hole Insert Rod Series Sucker Rod Pump
Product Overview
The Well Down Hole Insert Rod Series Sucker Rod Pump is engineered for reliable oil extraction operations, featuring seven major components: standing and traveling valves, plunger, barrel, seating assembly, pull tube or valve rod (for insert pump), and assembly fittings.
Operating Principle
A Sucker Rod Pump operates through a precise mechanical cycle:
  • A motor and gear box drive the power shaft
  • Counter weights on the cranks are lifted by the mechanism
  • Pitman arms connect the walking beam with cranks, lowering the plunger during the downstroke
  • During the upstroke, the horsehead and plunger lift fluid from the bottom to the surface
  • Valve operation is fluid-controlled: standing valve opens and riding valve closes during upstroke; standing valve closes and riding valve opens during downstroke
