Three Disadvantages of a Hydraulic Pump
There are many advantages of a hydraulic pump, but there are also some drawbacks. Listed below are three of the biggest disadvantages of this type of pump. This type of pump is best suited for onshore use, as it can produce very little oil and can only be used for relatively shallow depths. A major disadvantage of this type of pump is that it cannot handle large volumes of fluid, which means that it is not suitable for use in deeper wells.
The first disadvantage of hydraulic pumps is that they are not very adaptable. Some types of wells may have a low-flow rate, requiring multiple pumps to reach the same depth. Another disadvantage of this type of pump is its limited production range, which is determined by the number of stages in the system. These pumps also require tubing to be removed for repairs or replacement. This type of pump is also difficult to operate when high-GOR fluids are present, as the process of changing production rates requires pulling the tubing.
The second disadvantage of a hydraulic pump is its size and weight. Most pumping units use direct current motors, which are more expensive initially than a hydraulic pump. DC motors cannot be powered through utilities and require transformers to be changed, so they are not suited for high-power applications. They are also difficult to distribute and transmit. However, if you have a very large budget, a hydraulic pump is definitely worth the extra cost.
