pumps are heavy wall, stationary barrel, top anchor design insertable pumps. Available with either 3 cup type hold down (RHAC) or with a mechanical lock hold down (RHAM), RHA pumps allow a greater operating depth due to their heavy wall barrel. Insertable pumps can be removed from the well without having to remove the production tubing. Top anchor design means ideal for sandy wells.
An all-metal plunger pump, the type RH rod pump offers heavy-duty construction. The barrels are made from 3/16-in. wall tubing and are externally threaded, which provides extra strength and permits spacing the pump so that the plunger can stroke out both ends of the barrel. This stroke-through design combats buildup of scale on the inside of the pump barrel.
insert pumps are heavy-walled,stationary barrel, top anchor pumps recognized by as a standard design. These pumps are suitable for moderate depths with high sand fallback on well shutdown. Fluid dispersion directly above the seat nipple prevents the pump from becoming stuck in such a situation.
The Type A rod pump is widely used in petroleum recovery.
The locking device is located at the top. When the plunger moves, the sand around the locking device can be washed away to prevent the sand card, being easy to operate.
The pump can swing around the pivot point of the top locking device.
When the pumps position in the inclined well, the oil pipe and pump barrel are not damaged, the pump is slightly larger than that of the bottom fixed rod pump in the same fixed position, which is more suitable for low-yield and low-surface wells, and the top fixing device makes the pump itself have gas anchoring effect and can be used in oil wells with more gas.
