Multiple industries rely on high-tech liquid handling pumps. These pumps move not only blood, wastewater, and chemicals, but also oil and other fluids. While they all share the same fundamental principles of operation, there are differences based on the industry and application. In other words, for the upstream oil industry, it is essential to choose the appropriate type of pump.
Liquid Handling Pump Types
For the oil industry, the centrifugal pump is typically the only type used, which gets broken down by different classifications. With this pump, a profiled impeller creates a rotary motion that, along with a shaped pump housing, applies centrifugal force to push fluids out through the system. One advantage of centrifugal type pumps in the oil industry is that a valve on the discharge manifold can completely shut the flow off, even while running.
Another commonly used pump is the positive displacement type. This type gets used for smaller volumes of liquid but also when requiring high pumping pressure. The most popular positive displacement pumps use a piston that moves back and forth in a cylinder. This action increases the liquid’s pressure.
This particular type of pump gets classified as single-acting or double-acting. The single-acting positive displacement pump is typically used for high differential pressures and high operating speeds, while the double-acting positive displacement pump is a reciprocating type. That means filling of the cylinder and discharging of the fluid occurs with just one stroke.
By using the appropriate pump in the oil industry, the result is a continuous flow of fluid. Among centrifugal pumps are unique characteristics. For instance, some have a single impeller and casing, whereas, others have multiple. Even casing designs vary, either one- or two-piece. The suction, otherwise known as the inlet to the pump, is another distinguishing factor between liquid handling pump types.
Regardless of the application within the oil industry, efficiency, reliability, and safety are three of the most critical factors when choosing a pump. You want equipment that will operate seamlessly, meaning there are no issues of cavitation.
