| Top Hold-Down Insert Pumps, Thin Wall (RWA) and Heavy Wall (RHA) | |
| The Harbison-Fischer API style Top Hold-Down Pump is popular in areas that produce sand or other particulates that tend to accumulate over the hold-down of a Bottom Hold-Down. The fluid discharge point of the Top Hold-Down Pump is only inches away from the location of the hold-down, making it difficult to stick it in the tubing. Other advantages are that the Top Hold-Down Pump has greater fluid submergence than the Bottom Hold-Down Pump and there is not a stagnant fluid area between the hold-down and the fluid discharge point. The Top Hold-Down Pump is not as rugged as the bottom hold-down since the outside of the pump is only subjected to formation pressure. |
