Stationary Barrel Bottom Anchor Rod Pump-RHBC And RHBM
It’s suitable for deep well since the barrel only bears pressure from outside and does not bear tensile load and its clearance change is small.
But it is not recommended for sandy wells since there is no calculation for the well fluid around the outside of the barrel so pump may become stuck in the tubing by packed sand.
