Oil Injected Screw Pumps. Oil injected screw vacuum pumps are positive displacement pumps which use two intermeshing rotors with helical screws to compress gas. They use oil as a sealing and cooling medium. They are commonly used in industrial applications for their high pumping speed, low ultimate pressure, and reliable performance.
Centrifugal pumps are widely used in various industries for transferring fluids from one place to another. The efficiency and performance of a centrifugal pump greatly depend on the design and operation of its suction line. One crucial factor to consider in the suction line design is the velocity of the fluid flowing through the pipes. Maintaining the right suction line velocity is essential to prevent cavitation, ensure smooth operation, and maximize the pump's efficiency.
Suction Specific Speed can be used to determine stable and reliable operations for pumps with max efficiency without cavitation. Viscous Liquids - Max. Delivery Flow Velocities
Pump Suction Velocity
The velocity of the fluid in the suction line of a centrifugal pump plays a significant role in the pump's performance. The recommended suction velocity varies depending on the diameter of the pipe. It is crucial to ensure that the velocity of the fluid in the suction line is within the specified range to avoid issues such as cavitation, which can damage the pump and reduce its efficiency.
Suction Flow Velocity Calculation
Calculating the velocity of water in a pipe is essential to determine if the flow rate is within the recommended range for a centrifugal pump. The velocity of water in a pipe can be calculated using the formula:
\[ V = \frac{Q}{A} \]
Where:
- \( V \) = Velocity of water in the pipe (m/s)
- \( Q \) = Flow rate of water (m³/s)
- \( A \) = Cross-sectional area of the pipe (m²)
By calculating the suction flow velocity, you can ensure that the fluid is flowing at the optimal rate to maintain the pump's efficiency and prevent any potential issues.
Suction Flow Velocity Diagram
A suction flow velocity diagram provides a visual representation of the recommended velocities in the suction pipes of a water pump based on the pipe diameter. This diagram helps pump operators and designers to quickly determine if the flow velocity falls within the acceptable range for optimal pump performance.
Maximum Suction Flow Velocity
The maximum suction flow velocity refers to the highest velocity at which the fluid can flow through the suction line without causing cavitation or other operational issues. Exceeding the maximum suction flow velocity can lead to inefficiencies, pump damage, and decreased performance. It is essential to adhere to the recommended maximum velocity to ensure the pump operates smoothly.
Suction Specific Speed Pump
The suction specific speed of a pump is a critical parameter that influences the pump's performance and efficiency. It is a dimensionless number that relates the pump's flow rate, head, and speed. Understanding the suction specific speed of a centrifugal pump is essential for selecting the right pump for a specific application and ensuring optimal performance.
Centrifugal Pump Flow Rate
The flow rate of a centrifugal pump is the volume of fluid that the pump can transfer in a given time. It is crucial to maintain the correct flow rate to ensure the pump operates efficiently and effectively. Monitoring the flow rate and adjusting the suction line velocity accordingly can help optimize the pump's performance and prevent any issues related to cavitation or inefficiencies.
Suction Fluid Velocity Chart
A suction fluid velocity chart provides a comprehensive overview of the recommended velocities for different pipe diameters in the suction line of a centrifugal pump. This chart serves as a valuable reference tool for pump operators and designers to ensure that the fluid is flowing at the optimal velocity to maintain the pump's efficiency and longevity.

Conversely, if off-idle acceleration does not feel crisp or clean, then the pump nozzle size may already be too large. In this case a smaller size is required. Holley accelerator pump nozzles are stamped with a number (Figure 5) which indicates the drilled pump hole size. For example, a pump nozzle stamped “35” is drilled .035".Horizontal general twin screw pumps are heavy-duty, general-purpose pumps .
