Harbison Fischer Sucker Rod Subsurface Reciprocating Pump
Sub-Surface Pumping The sub-surface pump displaces the fluid at the bottom of the well thus lowering the bottom hole pressure. The movement of the plunger and the traveling valve helps to create a low pressure thus moving fluid up the well. The traveling valve is opened on the down stroke and closed on the upstroke.
