When it comes to industrial and commercial operations, the pump you choose can make or break your system’s performance. Whether you’re managing a wastewater facility, working in agriculture, or supporting a manufacturing process, selecting the right pump for your application is critical.
With decades of experience in pump sales, service, and system design, General Pump Chicago has helped countless businesses across the Midwest choose reliable, efficient pump solutions. In this guide, we’ll walk you through key considerations, common pump types, and expert tips so you can make the best possible selection.
Why Choosing the Right Pump Matters
A pump that’s incorrectly sized, improperly matched to the application, or built with the wrong materials can lead to:
-
Reduced efficiency and higher energy bills
-
Frequent breakdowns or premature wear
-
Costly system failures or downtime
-
Safety hazards for operators and equipment
The right pump, on the other hand, ensures optimal flow, consistent pressure, energy efficiency, and long service life.
Step-by-Step Guide: How to Choose the Right Pump
1. Define Your Application
Before browsing models or brands, start with a clear understanding of your application:
-
What will the pump handle? Water, slurry, chemicals, wastewater, oils, etc.
-
Is it continuous or intermittent use?
-
Is the system under high pressure or low pressure?
-
What’s the flow rate needed?
-
Is it a clean liquid or contains solids/abrasives?
-
What is the temperature and pH of the fluid?
Every detail about the liquid you’re pumping helps determine what type of pump and material of construction will work best.
2. Determine Flow Rate Requirements
Flow rate (usually measured in gallons per minute or GPM) is one of the most crucial variables. You need to know:
-
Minimum and maximum flow rates
-
Whether a variable or constant flow is required
-
Pressure head requirements (vertical lift or total dynamic head)
This data helps prevent both underperformance and overengineering.
3. Consider the Pumping Environment
Your pump will need to operate in a specific setting. Ask:
-
Is it a dry or wet location?
-
Indoors or outdoors?
-
What’s the ambient temperature?
-
Are there explosion risks or safety concerns?
Environmental factors help determine whether you need a sealed, explosion-proof, or weather-resistant pump housing.
4. Select the Right Pump Type
Here are some common types of industrial and commercial pumps we offer at General Pump Chicago, and when they’re used:
Centrifugal Pumps
-
Ideal for: General liquid transfer, clean water, light chemicals
-
Pros: Simple design, high flow rates
-
Limitations: Not ideal for thick or viscous fluids
Positive Displacement Pumps
-
Ideal for: Viscous fluids, slurries, dosing chemicals
-
Types include: Gear pumps, diaphragm pumps, peristaltic pumps
-
Pros: Excellent for precision dosing and high-viscosity liquids
Submersible Pumps
-
Ideal for: Dewatering, wastewater, sump systems
-
Pros: Can operate while fully submerged
Booster Pumps
-
Ideal for: Increasing water pressure in buildings or irrigation systems
-
Pros: Improves pressure without large infrastructure changes
High-Pressure Plunger Pumps
-
Ideal for: Pressure washing, reverse osmosis, hydrostatic testing
-
Pros: Handles high pressure with precision and reliability

5. Choose the Right Materials
Different pump materials suit different fluids and environments:
-
Cast iron: Durable and affordable for general use
-
Stainless steel: Excellent for corrosion resistance (ideal for food-grade or chemical use)
-
Bronze: Great for marine or brackish water environments
-
Plastics/Polypropylene: Used for highly corrosive chemical handling
Corrosion, erosion, and chemical compatibility must always be considered when choosing materials.
6. Understand Power Requirements
Most pumps require electrical, diesel, or hydraulic power. Make sure to:
-
Match voltage and phase (e.g., 230V single-phase or 480V three-phase)
-
Consider energy efficiency ratings
-
Ensure compatibility with your system’s controls or automation requirements
7. Maintenance and Serviceability
The best pump is one that can be easily maintained. Look for:
-
Readily available replacement parts
-
Manufacturer support and warranty
-
Compatibility with your service provider

FAQs: Choosing the Right Pump
Q1: What happens if I choose the wrong pump?
A: The wrong pump can cause inefficiency, excessive wear, overheating, or even system failure. It can also result in safety risks and higher maintenance costs.
Q2: How do I calculate my required flow rate?
A: Flow rate depends on the volume of fluid moved per unit of time. It’s usually calculated based on system demand, tank size, or process cycles. We can help calculate this based on your specs.
Q3: Can I use one pump for multiple applications?
A: Possibly—but only if all applications share the same fluid characteristics, pressure, and flow needs. In most cases, it’s best to use pumps tailored to each task.
Q4: What’s the difference between centrifugal and positive displacement pumps?
A: Centrifugal pumps are ideal for high-volume, low-viscosity fluids. Positive displacement pumps are best for thick, viscous, or abrasive fluids that require precise flow rates.
Q5: How often should a commercial pump be serviced?
A: Service intervals vary by pump type, usage, and environment. Routine maintenance (monthly or quarterly) is recommended, with annual inspections for wear and performance tuning.
Q6: What brands do you work with?
A: We carry and service trusted brands like Grundfos, Gorman-Rupp, Cat Pumps, and more. We ensure high availability of parts and fast turnaround on service.
Final Tips for Choosing the Right Pump
-
Don’t buy based on price alone – Lower-cost pumps may have higher operating or maintenance costs.
-
Invest in a trusted supplier – Work with experienced professionals who understand real-world conditions.
-
Request a system evaluation – An on-site assessment can uncover hidden variables and save you money.
-
Think long term – Consider the total cost of ownership: energy use, service intervals, and parts availability.
