Product Description

The whole pump can be assembled and connected to the lower end of the sucker rod on the ground, run into the well as a unit, and fixed in the tubing by seating nipple pre-fitted in the tubing at the required depth (pump setting depth). The workover operation time for a rod pump well is much shorter than a tubing pump well by at least 50%. Rod pump have three types, they are Traveling Barrel Bottom Anchor Rod pump, Stationary Heavy Wall Barrel Bottom Anchor Rod Pump and Stationary Heavy Wall Barrel Top Anchor Rod Pump.

1)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 circulation for the well fluid around the outside of the barrel so pump may become stuck in the tubing by packed sand.

2)Stationary Barrel Top Anchor Rod Pump-RHAM and RHAC

The top anchored pump with stationary barrel is suitable for sand production well since the fluid discharged from the guide cage washes away the sand between tubing and the top of the pump. But the pump barrel is more subject to inside pressure and tensile load caused by the fluid column, and the plunger clearance will intend to increase during up stroke so the top anchored pumps are not recommended in deep wells.
