Top 5 Factors to Keep in Mind When Choosing an Industrial Pump

Choosing the right industrial pump for your application involves several key considerations. So, if you’re wondering: how do I choose a pump in industry?, here are a few steps to help you along the way and make an informed decision:

•  Understand Your Application: Define the technological process outline and main process parameters, such as flow, pressure, and temperature. Consider the specific requirements of your application, including fluid properties, flow rates, and system parameters.
• Know Your Fluid: A complete knowledge of the fluid to be handled in each pumping operation is crucial. This includes the type of fluid, temperature, density, viscosity, vapour pressure, solids in suspension, toxicity, and volatility.
• Consider the pipe: Before talking about a pump, consider the pipe. The velocity of liquid in pipes ranges from 3 to 10 feet per second (ft/sec). If the liquid is moving too slowly, things like dirt and sludge might sink to the bottom. But if it’s flowing too fast, it can cause the pipe to wear out faster due to abrasion.
• Pressure: Now that we have the pipe, pressure is the next step. Pressure comes from friction and elevation.
• Pump Type: Preliminary selection of the pump type, design, position, driver, type of sealing, and cooling of the seal and bearings, if required.
• Drive Unit: Establishing the type of drive unit (electric motor, steam turbine, etc.) and its main operating parameters.

Remember that failing to select the appropriate pump for a given use case can result in inefficient operation at best and catastrophic equipment failure at worst. Therefore, it’s essential to choose wisely.

How do I choose a pump in industry?

When selecting an industrial pump, there are several factors that you should consider:

• Type of Fluid: The type of fluid you’re pumping affects the type of pump you choose. You need to consider the fluid’s viscosity, temperature, corrosiveness, and whether it contains solids.
• Flow Rate: The flow rate is a critical factor in pump selection. It’s usually measured in gallons per minute (GPM) or cubic metres per hour (m³/h). The pump you choose must be able to handle your application’s flow requirements.
• Pressure Requirements: The pump must be able to generate the necessary pressure for the fluid to flow at the required rate.
• Efficiency: Pump efficiency is a measure of how well a pump converts its input power into fluid movement. You’ll want to choose a pump that offers the best balance of power consumption and performance.
• Installation and Maintenance: Consider how easy it is to install and maintain the pump. Some pumps require more maintenance than others.
• Cost: Consider both the initial cost of the pump and the operating costs. While some pumps may be cheaper to buy, they could be more expensive to run and maintain.

Remember, choosing the right pump for your application is crucial for efficient and safe operation. Other factors to consider before choosing any industrial pump

• Material Compatibility: The materials used in the construction of the pump must be compatible with the fluid being pumped. This is to prevent corrosion, erosion, and other forms of material degradation that could compromise the pump’s performance and lifespan.
• Maintenance and Reliability: Industrial pumps are often subjected to harsh operating conditions, so they need to be robust and reliable. Some pumps require more maintenance than others, so it’s important to consider how much time and resources you’re willing to dedicate to pump maintenance.
• Energy Efficiency: Energy efficiency is a key consideration, especially for applications where pumps operate continuously. More efficient pumps consume less power for the same output, leading to significant energy savings over time.
• Cost of Ownership: The total cost of ownership includes not only the initial purchase price of the pump but also installation costs, operating costs, maintenance costs, and potential downtime costs. It’s important to consider all these factors when choosing a pump.
• Supplier and Manufacturer Reputation: It’s equally important to consider the reputation of the pump supplier and manufacturer. A reputable supplier will provide high-quality products and excellent customer service, while a reputable manufacturer will have a track record of producing reliable and durable pumps.

Remember, choosing an industrial pump is a complex process that requires careful consideration of many factors. It’s always a good idea to consult with a pump specialist or engineer if you’re unsure.

Retrofitting industrial pumps is a cost-effective approach to improve performance, extend equipment lifespan, and adapt to changing process requirements. However, retrofitting requires meticulous planning, technical knowledge, and adherence to best practices to ensure safety, efficiency, and long-term operational success. Let’s explore some of the best practices for retrofitting an industrial pump with insights into evaluation, planning, execution, and post-retrofit maintenance.

“The most important thing to keep in mind is to make sure your next equipment retrofit is made to last,” says HOMA Product Manager Nick Terranova. “Retrofits are inherently about problem solving. When we talk about retrofitting a pump, we are taking an existing installation that was designed and constructed to use a given pump and replacing it with a different pump, either from a different manufacturer or a different model from the same manufacturer.”

This is a common practice. A pump station will almost always outlast its initially purchased pump, and when that happens, there are plenty of reasons why you would either want to, or need to, replace that pump with something other than just the same thing.

“Typically, you’re not going to replace a functional pump, which means that whatever pump was in there failed for some reason,” Terranova explains. “That could be that it lived a long, productive life, hit the end of its serviceability, and now you need to replace it with a newer model since the last one is no longer produced. It could also be that the pump never ran correctly, or it was a nightmare to work on and you are sick of dealing with it.”

It’s also common that if a pump goes down, it’s far more important to get a pump in place than to replace it with the exact same model that failed. “This is where the most problems come from in retrofits—acting quickly to fix a problem.”

Common Retrofit Problems to Avoid

The most obvious problems are the physical constraints of the installation, such as the size of the new equipment. Usually these are addressed beforehand however, something that can be missed is that not every pump manufacturer uses the same mounting configuration on their pumps. Some use ANSI flanges, some use DIN flanges, and others use proprietary arrangements.

“If you aren’t careful to verify what you have and what you will be receiving, you may end up with a problem when it comes time to the install,” Terranova says. “That’s why it’s important to communicate what you will be replacing to the supplier, who will have a lot more experience retrofitting equipment and should know all the particular precautions.”

A good supplier should be able to help with any electrical or control requirements. It’s important to ensure that the panel is sized appropriately for the new pump, and that any differences in sensors or controls is considered. Equally important is considering the pump as part of the complete system rather than just as a component.

“It is very common to only provide a single operating point when looking to cross a pump over from one to another,” Terranova says. “There can be a huge differential from what you think the operating point is, or what it was when the pump station was designed 10 years ago.”

If you are retrofitting a pump that failed, remember that there is likely a reason that the pump failed, and replacing it with the exact same pump may cause the new one to fail in the same way.

Top 10 Best Practices for Retrofitting a Pump

Let’s explore some of the best practices for retrofitting municipal and industrial pumps.

1. Conduct a Comprehensive System Assessment

Before beginning any retrofit project, perform a comprehensive assessment of the current pumping system. Gather historical performance data—including flow rates, pressure, temperature, energy consumption, and downtime incidents. Evaluate the mechanical condition of the pump components—including impellers, seals, bearings, and casings, to identify wear or damage.

Examine the compatibility of the pump with associated systems such as piping, valves, motors, and control systems. And perform a root-cause analysis to identify any recurring performance issues, such as cavitation, vibration, or excessive noise, to address underlying problems during the retrofit.

During this step, it’s also important to define your retrofit objectives so that you can align the outcomes with the organizational goals. For example, your goal may be to enhance energy efficiency to reduce operating costs and environmental impact. Another common objective is to upgrade the pump to handle higher flow rates or pressure demands. Many retrofits include replacing outdated components to minimize downtime and improve operational stability.

When making this assessment, ensure that the system meets any updated safety, environmental, or industry-specific standards.

2. Collaborate with Experts You Can Trust

Partnering with experienced professionals is crucial for a successful retrofit. Consult the pump’s manufacturer for recommendations about upgrades or replacement parts and work with specialists to analyze system requirements and design customized solutions.

“It’s important to work with people you can trust,” Terranova recommends. “Sometimes, you don’t need a full pump replacement and sometimes you need many additional upgrades to achieve your goals. You want to work with people who are available to help make any diagnoses and recommendations that are in your best interest.”

3. Develop a Detailed Retrofit Plan

Create a comprehensive plan outlining each phase of the retrofit process. The plan should include the scope of work, the timeline, a realistic budget, and a complete risk assessment.

Define the specific modifications, replacements, and installations to be performed. Establish a realistic project schedule, accounting for procurement, downtime, and testing. Estimate costs, including materials, labor, and contingency funds for unexpected issues. And finally, identify potential risks and develop mitigation strategies, such as backup systems or alternative processes.

4. Evaluate Technology Upgrades to Enhance the Retrofit

Modernizing a pump system often involves incorporating advanced technologies. For example, you may want to implement variable frequency drives (VFDs) to optimize motor speed and match pump output with system demand, improving efficiency. It may be a good idea to replace worn components with corrosion-resistant or wear-resistant materials to extend service life.

A pump retrofit is also a good time to consider an upgrade to advanced mechanical seals or seal-less designs to reduce leaks and maintenance requirements. You may also want to implement IoT-based monitoring systems for real-time performance tracking and predictive maintenance. An experienced technical professional can help advise you on all these potential enhancements.

5. Prioritize Energy Efficiency

Energy consumption is a significant cost factor in pump operations. To improve efficiency, consider an optimized hydraulic design. Redesign impellers and volutes to minimize energy losses.

This is where correct sizing plays a key role. Ensure the pump’s capacity matches the system requirements to avoid over-pumping or under-pumping. Evaluate the entire system for inefficiencies, including pipe friction losses and valve restrictions. Conduct energy audits before and after the retrofit to quantify improvements.

6. Ensure Compliance with Standards

Adhere to relevant industry standards and regulations during the retrofit. Common standards include:

• API Standards: For pumps in the oil and gas industry, ensure compliance with API 610 or API 682.
• ISO Standards: Follow ISO or ISO for general-purpose industrial pumps.
• Environmental Regulations: Address emissions, noise levels, and waste management requirements.

Compliance ensures the retrofit meets legal and operational requirements, reducing liability and enhancing system reliability. A professional technician can help you ensure that these requirements are met.

7. Execute the Retrofit with Precision

During the execution phase, attention to detail is critical. Inspect all replacement components for defects and verify compatibility. Ensure precise alignment between the pump and motor to minimize vibration and wear. It’s crucial to perform thorough checks during and after installation to verify workmanship. Also, be sure to maintain detailed records of modifications, parts used, and installation procedures for future reference.

8. Perform Comprehensive Testing

After completing the retrofit, conduct rigorous testing to validate performance. Testing should include:

• Performance Testing: Measure flow rates, head, efficiency, and power consumption to ensure they meet design specifications.
• Vibration Analysis: Detect abnormal vibrations that could indicate alignment issues or mechanical defects.
• Operational Simulations: Test the pump under various load conditions to confirm reliability and adaptability.

9. Implement Post-Retrofit Maintenance

A successful retrofit does not end with installation.

“The last thing you want to do is install a brand, new pump, and then ignore regular preventive maintenance,” Terranova says. “Being proactive with maintenance can prevent critical failure down the road and extend the lifespan of your retrofit.”

It is important to establish a proactive maintenance program to sustain performance. Regular inspections should include monitoring critical components such as bearings, seals, and impellers for wear and consider keeping spare wear items available to ensure quick repairs when there are issues. It’s a great idea to leverage digital monitoring tools to track performance metrics and predict maintenance needs. And don’t stop there. Provide operators and maintenance personnel with training on the upgraded system’s features and requirements.

“There’s no better motivation to keep a good maintenance schedule then throwing down thousands of dollars for a brand-new pump,” Terranova says. “You want to protect that investment and prevent future damage.”

10. Evaluate Retrofit Outcomes

Finally, assess the success of the retrofit by comparing pre- and post-retrofit performance data. Evaluate things like efficiency gains by quantifying energy savings and calculating the return on investment (ROI). Measure reductions in downtime and maintenance costs to track reliability and verify that the system meets new capacity or process requirements. Don’t forget to assess reductions in emissions or waste generation.

Retrofits That Are Made to Last

Retrofitting a municipal or industrial pump can yield significant benefits, from cost savings to enhanced operational performance. By following these best practices—from thorough system assessments to post-retrofit evaluations—organizations can ensure a successful retrofit that aligns with their technical and financial objectives. Investing time and resources into proper planning and execution will pay dividends in the form of improved efficiency, reliability, and compliance.

“My best advice is to do your due diligence before the retrofit,” Terranova says. “The more detailed and granular information you have at the start, the better. And make sure you understand why the pump failed in the first place so you can address that problem and avoid it in the future. Then work with professionals like HOMA, who are committed to your best interests. We will help you identify the problem and find the best possible solution for your system.”
