When it comes to choosing between screw pumps and gear pumps for various applications in the petroleum industry, it is essential to consider the advantages and disadvantages of each type of pump. In this article, we will focus on the advantages of screw pumps over gear pumps and explore the reasons why screw pumps are preferred in certain situations.
Screw Pumps and gear pumps utilize the same pumping technology and are from the same pumping family of positive displacement
Gear Pump vs. Screw Pump
Gear pumps and screw pumps are both positive displacement pumps commonly used in the petroleum industry. While gear pumps have been traditionally popular due to their simplicity and cost-effectiveness, screw pumps offer several distinct advantages that make them a preferred choice for certain applications.
One of the primary advantages of screw pumps over gear pumps is their ability to handle high viscosity fluids with ease. Screw pumps are designed to efficiently move thick, viscous liquids such as heavy crude oil, bitumen, and other challenging fluids that may cause issues for gear pumps. The unique design of screw pumps allows for smooth and consistent flow even with highly viscous fluids, making them ideal for applications where gear pumps may struggle.
Screw Pump vs. Progressive Pump
Another advantage of screw pumps over gear pumps is their ability to handle abrasive fluids and solids without clogging or damage. In comparison, gear pumps are more susceptible to damage from abrasive particles present in the fluid being pumped. Screw pumps have a larger clearance between the rotating elements, allowing them to handle particles and solids without compromising performance or efficiency.
Screw Pumps and Pressure
Screw pumps are also known for their ability to maintain a steady flow rate and pressure, even when operating at high pressures. This makes screw pumps suitable for applications where a consistent pressure is critical, such as in oil and gas production, chemical processing, and other industrial processes where precision and reliability are essential.
What is a Screw Pump?
A screw pump is a type of positive displacement pump that uses one or more screws to move fluid through the pump. The rotating screws create a continuous flow of fluid by trapping and pushing the liquid through the pump chamber. This design results in a smooth and pulsation-free flow, making screw pumps ideal for applications where a consistent and steady flow is required.
Screw Displacement Pumps
Screw pumps, also known as screw displacement pumps, are available in various configurations, including single screw pumps, twin screw pumps, and triple screw pumps. Each type of screw pump offers unique advantages and is suitable for different applications based on the fluid properties, flow rate requirements, and operating conditions.
Screw Pump Housing
Whilst a gear pump is a more than acceptable option for the handling of lubricating fluids, the design of the screw pump has several advantages over it. To make these features as clear as possible, we have …
A check valve should be normally provided on the pump discharge to avoid reverse flow when the pump is not in operation. Downstream to the check valve on the pump discharge, minimum flow recirculation line for the pump needs to .
