Centrifugal Pump vs. Gear Pump
Centrifugal pumps and gear pumps are two common types of pumps used in various industrial applications. Centrifugal pumps work on the principle of using centrifugal force to move liquids, while gear pumps use the meshing of gears to pump fluids. When it comes to feeding a gear pump with a centrifugal pump, it is essential to consider the differences in their operating principles.
Centrifugal pumps are known for their high flow rates and are well-suited for applications where a large volume of liquid needs to be moved quickly. They are efficient in handling low-viscosity liquids and are commonly used in processes such as water treatment, irrigation, and HVAC systems. On the other hand, gear pumps are better suited for handling viscous fluids, such as oils, paints, and syrups. They are also compact in size and offer a steady flow rate, making them ideal for applications that require precise fluid delivery.
When feeding a gear pump with a centrifugal pump, it is important to ensure that the centrifugal pump is capable of providing the necessary flow rate and pressure to meet the requirements of the gear pump. Additionally, proper sizing and selection of both pumps are crucial to ensure optimal performance and efficiency in the system.
Running Gear Pump in Reverse
In some cases, it may be necessary to run a gear pump in reverse to achieve a specific pumping direction or to control the flow of the fluid. Running a gear pump in reverse can be achieved by reversing the direction of the motor or by using a reversible gear pump design. However, it is important to note that not all gear pumps are designed to run in reverse, and doing so without proper consideration can lead to damage to the pump and reduced efficiency.
When considering running a gear pump in reverse, it is essential to consult the pump manufacturer's guidelines and specifications to ensure that the pump is capable of operating in reverse safely. Additionally, proper precautions should be taken to prevent any potential issues, such as cavitation or overheating, that may arise from running the pump in reverse.
Viking Gear Pump Flow Directions
Viking gear pumps are a popular choice for handling a wide range of fluids, including viscous liquids, chemicals, and food products. These pumps are known for their robust construction, reliable performance, and versatility in various applications. When feeding a Viking gear pump with a centrifugal pump, it is important to understand the flow directions and configurations of the pump to ensure proper operation.
Viking gear pumps typically have two main flow directions: internal gear rotation and external gear rotation. In internal gear rotation, the fluid is trapped between the gear teeth and the pump casing, creating a positive displacement action that moves the fluid through the pump. External gear rotation, on the other hand, involves the fluid being carried between the gear teeth and the pump casing, generating a suction effect that draws the fluid into the pump.

The main working parts of G series screw pumps are eccentric screws and fixed bushings. Due to the special geometry of the two parts, an independent sealing chamber is formed, the medium flows uniformly from the axial direction, the internal flow rate is low, the volume is constant, the pressure is stable, and vortex and agitation do not occur.
