The most expensive component of a hydraulic system, a hydraulic pump generates atmospheric pressure and propels the liquid through the inlet line of the pump. The fluid flow then passes through a hydraulic filter and strainer before being routed to the attached hydraulic machinery. The mechanical energy from the gears in the pump is transferred to the fluid, which powers the attached hydraulic machinery. Disadvantages of hydraulic pumps
Some of the disadvantages of hydraulic pumps include the difficulty in pumping produced fluids with high solids content. A hydraulic pump is more efficient when a lighter power fluid is mixed with the heavy produced fluid. Other disadvantages of hydraulic pumps include the potential for fire hazards, especially if oil is used as the power fluid. Some installations require dual strings of tubing, which can reduce the pump’s efficiency. While the advantages of hydraulic pumps outweigh the disadvantages, there are certain factors to consider before purchasing one.
One disadvantage of hydraulic pumps is that the pumps use gas, which will lead to a significant voltage drop if several pumps are connected to a single power source. Because of this, it is important to select a pump with a high-quality motor to avoid potential electrical shock. Moreover, the pressure of the liquid can be too low to produce sufficient production without pumping. Those who want to boost flow rate should choose a pump with artificial lift.
