Why Choose Us
1. Description:
The rod pump is assembled on the surface and then connected to the sucker rod before being lowered into the well through the tubing. This makes it easy for inspection and workover operations, as the pump can be easily pulled up and down through the tubing, making it ideal for deeper wells. This design also helps extend the life of the tubing by reducing the number of times the tubing threads are tightened or loosened, as well as minimizing the frequency of workover operations.
2. Features:
The plunger’s surface is coated with a nickel alloy, while the inside wall of the barrel is coated with hard chrome, offering excellent wear resistance and durability. All key components, such as the valve casing, ball, and seat, are made from high-quality materials that provide strong corrosion resistance and superior mechanical properties. These features ensure reliable performance even under harsh conditions.
3. Our Product Range:
We offer a wide range of oilfield equipment including pumping units, tubing pumps, sucker rods, Christmas trees, casing heads, casing pipes, tubing pipes, drill pipes, polished rods, and couplings.
