Horizontal VS Vertical Flooded Suction Pump: Which Should You Choose?

When choosing between horizontal and vertical slurry pump mounting configurations, some main factors to consider include the type of slurry being pumped, the required flow rate and pressure, the distance the slurry needs to be pumped, and the available power source. In addition, the operating environment should be taken into account when selecting a slurry pump. This includes the temperature and pH of the slurry, as well as any potential corrosion or erosion that may occur. Choosing a pump with materials that are resistant to these factors will help to ensure its longevity and reliability.

Important Specifications to Consider When Selecting a Flooded Suction Pump

There are several important factors to consider while choosing flooded suction pump specifications for your application:

  • Pump Design: Look for a pump specifically designed for flooded suction applications. The flooded suction pump design should have a robust construction to handle the fluid and ensure reliable operation.
  • Flow Capacity: Consider the required flow rate for your application. The pump should be able to handle the desired volume of fluid efficiently.
  • Head Pressure: Evaluate the head pressure, which is the vertical distance the pump needs to lift the fluid. Ensure that the pump can handle the required head pressure without losing performance.
  • Material Compatibility: Check the pump’s material construction to ensure compatibility with the pumped fluid. Different fluids may require specific materials such as stainless steel, cast iron, or high-density polyethylene.
  • Motor Power and Efficiency: Consider the power rating and efficiency of the pump’s motor. A higher power motor may be needed for more significant flow rates or when pumping thicker fluids.
  • Seal Options: Look for pump models with reliable sealing options to prevent leakage and maintain optimal performance.
  • Installation and Maintenance: Evaluate the pump’s ease of installation and maintenance requirements. Consider factors such as accessibility for servicing and the availability of spare parts.
  • Safety Features: Check for features, such as overload protection, thermal sensors, and built-in safeguards to protect the pump and prevent damage.
  • Manufacturer’s Reputation: Consider the reputation and experience of the pump manufacturer. Look for companies with a track record of producing reliable, high-quality pumps.

Advantages of Using Flooded Suction Pumps in Different Applications

Flooded suction pump applications are in broad ranges, including wastewater treatment, mining, construction, and other industries where the handling of slurries and challenging fluids is required. Standard advantages of flooded suction pumps include: 

  • Priming: Flooded suction pumps are self-priming, meaning they can draw fluid into the pump without needing external priming. This simplifies the installation process and eliminates the need for additional priming equipment.
  • Efficient Operation: The flooded suction design ensures that the pump remains filled with fluid, reducing the risk of cavitation and ensuring consistent and efficient operation.
  • Versatility: Flooded suction pumps can handle a wide range of fluids, including liquids with high solids or slurries. This makes them suitable for wastewater treatment, mining, construction, and industrial processes.
  • Reduced Maintenance: With their reliable design and efficient operation, flooded suction pump systems often require minimal maintenance, resulting in lower downtime and reduced maintenance costs.
  • Enhanced Durability: Flooded suction pumps are designed to handle challenging fluids, including corrosive or abrasive substances. They are built with durable materials and components to withstand harsh operating conditions and extend the pump’s lifespan.
  • Cost-Effective Solution: The efficiency, reliability, and low maintenance requirements of flooded suction pumps contribute to cost savings over the pump’s lifecycle.

Benefits of Flooded Suction Pumps in Handling Slurries and Other Challenging Fluids

Flooded suction pumps offer specific benefits when it comes to handling slurries and challenging fluids:

  • Solid Handling Capability: Flooded suction pumps are designed to hold fluids with a high concentration of solids or slurry-like consistency. They can effectively transport and pump liquids containing particles, debris, or abrasive materials.
  • Reduced Clogging: The design of flooded suction pumps allows for the passage of solids without clogging or blockage, ensuring continuous and uninterrupted operation.
  • Improved Efficiency: Flooded suction pumps operate more efficiently by minimizing the risk of clogging and maintaining a consistent flow, reducing energy consumption and maximizing productivity.
  • Enhanced Wear Resistance: Slurries and abrasive fluids can cause premature wear on pump components. Flooded suction pumps are built with materials and features that offer excellent wear resistance, increasing the pump’s durability and longevity.

Lower Maintenance Costs: The ability to handle slurries without clogging or excessive wear reduces the need for frequent maintenance or repairs, resulting in cost savings in labor and replacement parts.

Why EDDY Solids Handling Pumps are Better

High End Seal Support System
– Explained.


Pass solids from 1-12 inches (rocks, rags, debris). The EDDY Pump’s open rotor design with high tolerances allow anything that will go into the intake to be passed through the discharge without issues.

Tolerance between the rotor and the volute in the 4″ EDDY Pump easily allows the passage of a man’s arm (*see picture below). Compared with the tolerance in a centrifugal pump, the EDDY Pump easily wins. Pump Range spans 1-inch through 12-inch EDDY Pump line, the tolerance ranges from 1-12 inches. 

This translates to a significant amount of solids and debris pass through, without clogging the pump.  To learn more about the technology behind our pumps continue reading Here.
