Product Description


The Sucker rod pump is connected to sucker rod after being assemblied on the surface then it is pulled down to the well bottom through the tubing. Thus it is convenient for the inspection and workover because they can be pulled up and down through the tubing and suitable for deeper well. The life span of tubing can be prolonged for decreasing the times of the thread of the tubingbeing turned on and off and the time of the workover. The rod pump can be classified into two types of mechanical seating and cup seating. Also it is divided into three types as RHA (stationary heavy well barrel top anchor rod pump), RHB (stationary heavy well barrel bottom anchor rod pump) and RHT (travelling heavy well barrel bottom anchor rod pump).

Product wiki


A sucker rod pump is a type of oil prospecting pump commonly seen in fields in Texas in the US and other areas where potential oil deposits exist deep underground. It is capable of pumping oil from a depth of 10,000 feet (3.05 kilometers) or greater, and somewhat resembles the movement of a large pendulum turned on its side. There are many other names for the sucker rod pump in the oil prospecting industry, including pumpjack, nodding donkey, and horsehead pump, but they are all designed based on the same principles.

Each component of a sucker rod pump has a unique name as well, which may seem difficult to understand unless someone is familiar with the machinery. The individual parts all serve as jointed links in a mechanical chain reaction that gradually transfers circular motion to a general up-and-down pumping motion. The whole mechanism operates similarly to a crankshaft assembly in an automobile or train locomotive, or the cushioning armature on doors that automatically close at a slow rate to let someone pass through.
