Selecting an industrial pump application is not as simple as someone might think.  In fact, if the most important factors are not considered it can literally spell disaster and cause a company a lot of time and money trying to reverse or correct any issues resulting from having the wrong pump in the application.  The following article provides a concise overview of the specific selection criteria that can be used for choosing the best industrial pump for your needs.

When is it Time to Replace an Industrial Pump?

In a study that analyzed the life cycle costs (LCC) of industrial pumps, it was noted that the cost of unexpected downtime and loss of production due to pump failure can nearly equal or even surpass operation or maintenance costs. Therefore, it’s essential to know when to replace your industrial pump.

Recognizing the signs that you’ll soon need a replacement and being proactive can save money, time, and your reputation in the industry.

There are various indications and/or reasons for replacing a pump. The following are some of the more crucial ones:

  • Catastrophic failure. Because catastrophic failure will likely damage other parts of a pumping system, it is perhaps the most costly reason for replacing a pump. Hopefully, it can be avoided by recognizing earlier signs.
  • Visual wear. A visual inspection may reveal leaks, abnormal residue or deposits overheating, vibration and misalignment, or other indications of extreme wear.
  • Audible wear. Some signs of wear are not visible but audible. Pops, squeals, grinding noises, or oscillating fluctuations in the hum of operation may indicate failing components.
  • Decreased performance. Even when no audible or visual signs of extreme wear raise a red flag, decreased performance can indicate that it’s time to replace a pump. If you notice a marked decrease in expected performance, replacement may help to avoid more costly failure later.
  • Component failure. While a pump motor may be running well, other components may fail or show signs of extreme wear. These can be early indications that it’s time to replace a pump before catastrophic failure.
  • System upgrade. At times, newer technologies and products emerge in the industry that makes pumping more efficient or reduce maintenance costs. The decision to upgrade may mean pump replacement as well.
  • System correction. Sometimes accumulated experience reveals that the original pump was the wrong choice. Correcting to another pump type or model is another reason for the pump replacement.

DAE Pumps has the resources to help you troubleshoot your pumping system and determine whether you need to replace your pump(s).

What are the Primary Considerations for Selecting a Pump for an Application?

Application Type

DAE Pumps offers high-quality industrial pumps for the following applications:

  •             Agriculture
  •             Dewatering
  •             Dredging
  •             Mining
  •             Municipalities
  •             Oil and Gas
  •             Paper and Pulp

One pump can severely impact the production of an entire operation. Each application has its own variables and challenges, so feel free to contact the professionals at DAE Pumps for a consultation to help you choose the right pump for your application.  

Performance Requirements

Performance requirements include the motor output, flow rate, discharge head, net positive suction head (NPSH), and vacuum requirements. System head can be divided into three components: static head (pressure), elevation, and dynamic head (velocity). Weighing all these factors is crucial in determining the right pump for the job.

Piping and Hoses

Pipe diameter, length, and material have to be factored in, both on the inlet and outlet side of the pump, and friction loss can be a concern in certain applications. Improper pipe or hose sizing can put undue stress on the pump, slowing production, decreasing efficiency, and shortening the life cycle of the pump.

Fluid Properties

Fluid viscosity, specific gravity, temperature, and other properties will affect your calculations. Specific gravity can be likened to the weight the fluid puts on your pump, while viscosity can be compared to the fluid’s internal friction as it moves. Additional considerations like shear sensitivity (how viscosity changes when fluid is pressurized), solids concentration, and hazardous properties (such as flammability or explosivity) are crucial to designing a pumping system and choosing the right pump.

Pump Construction

Based on the application, pumps are constructed with various materials to withstand extreme temperatures, corrosive chemicals, and abrasive materials. Compatibility between a pump and the fluid it’s moving is critical in order to avoid catastrophic failure and personal injury.

Pump Installation and Location

Consider the pump’s environment and the ambient temperature of its location. Will it be submerged or flooded (positioned at the same level or below the fluid being pumped)? Will it need to operate in freezing conditions or high temperatures? Will it be installed inside or outside of the facility? Will it need to resist corrosion, abrasion? Will it need to operate in a hazardous environment?

Motor Power

A rule of thumb is to determine the power you need and then round up to the next highest horsepower rating. But the choices may be more complex than that. More power is needed for viscous fluids or fluids with high specific gravity. An underpowered pump, or a pump that has inadequate power in comparison to the force required to pump the fluid, will increase maintenance costs, impede production, and have a short life cycle.

Certification Requirements

In most industries, certification and compliance will also need to be a consideration. Applications that require a specific certification demand pumps that meet the industry certifications. Some examples are:

  •             EHEDGE
  •             CE
  •             UL
  •             FDA
  •             USDA
  •             ATEX
  •             And more…
