API RHB Pump / Precision Insert Type API Rod Pump with Heavy-Wall Barrel
The RHB Pump is installed at the bottom of the sucker rod string in the well and seated within a seating nipple located in the tubing string at a predetermined depth. The pump type ends with "C" if a cup hold-down is used, and with "M" if a mechanical hold-down is applied.
The API B-12 heavy-wall barrel features a maximum wall thickness of 0.25 inches and is externally threaded with an inside diameter tolerance of -0.000 to +0.002 inches. This pump can be assembled with various plungers and components to suit different well conditions. The RHB design includes a heavy-wall barrel and extension for stroke-through configurations.
