API-RHBM-AC, Rod, Stationary Heavy Wall Barrel, Mechanical Bottom Anchor And Cup Top Anchor Pump
Working principle: RHBM/AC rod pump is equipped with a bottom seating nipple N12 and top seating nipple N11, N12 and N11 fixed on a piece of tubing, as support assembly pump with tubing string down to the bottom of the well. Plunger assembly connection on the sucker rod string and with the pump overall down to support assembly position together , pump with fixed inside the support assembly, Plunger assembly with the sucker rod string up and down reciprocating movement to achieve pumping work.
RHBM/AC advantage: This kind of pump to achieve the top cup sealing and mechanical sealing at the bottom , the pump performance is more stable. if the pump appeared quality problem, need not put forward the tubing string, only need put the whole pump forward well through the sucker rod string together , operation is simple.
