What to Consider When Choosing a Pump

Knowing the specific fluid pumping requirements of an application up front in the development process is important. Unfortunately many device and system designers neglect to consider the fluid pumping requirements until late in the design process. Many times a designer will have to perform costly alterations to systems or devices to make their design compatible with a pump chosen late in the design process. Being that many times a pump is the “heart” of a system, it makes sense to begin the specification process early rather than later. Careful planning saves not only time and money, but also headaches.

Consider the following items when designing a device that requires a fluid pump:
• Will the pump be self-priming or will it require flooded suction? This is an important factor when considering the positioning and available space for the pump in the system or device.
• Available space and positioning: Problems arise when a design includes “space” for a pump but an actual pump has not been specified. There are many stories of OEMs requesting pumps to fit in small spaces, only to find out that the space will not accommodate the type and size of pump necessary to perform the application’s requirements. Specifying a pump early, rather than later, will assist in the sizing and positioning of a pump and its surrounding space. This promotes pumping efficiency and assists in eliminating costly redesigns.
•The system’s required flow and pressure: Many variables in a system impact the flow and pressure. Understanding the flow and pressure requirements is a starting point to choosing the correct pump. Adding a pump to the system also makes an impact. This is another reason that a pump should be specified early on.
• Wetted materials, fluid, fluid temperature: The materials of the pump components that will be in contact with the pumped fluids are the wetted materials. It is important to understand the materials of the pump and their inherent limitations. Are the materials chemically compatible with the fluid being pumped? Can the materials handle the temperature of the pumped fluid?• Power requirements: AC or DC?
• Environment (temperature, humidity, etc.) The environment plays an important role in pump performance and can affect the life of the pumps. For instance, is there a circulation of air present to help keep the pump cool or will the pump be in an environment where there is not much airflow? Will the environment be one of high humidity where the pump must be resistant to water?
• Continuous run: Does the application require that the pump run continuously or only in short intervals? Knowing the answer to this question, as well as understanding the surrounding environment (heat, humidity), will also affect the life of the pump and its design elements. As illustrated by the previous list, there are many items to consider when specifying a pump for an OEM application. While this list is a good starting point, there are many variables to consider when deciding on the right pump to get the job done. When in the process of specifying a pump, it is important to choose a supplier that is willing to listen to the specific needs of a project and make suggestions and proposals based on those needs.

Some things to consider when choosing a pump supplier:
• OEM or off-the-shelf pump? Does the supplier only offer off-the-shelf (OTS) pumps? This is fine if a pump is identified that matches up with a system’s requirements and specifications. However, considering the previous list, it could be difficult to find an OTS pump that is able to adapt to all of the application’s variables. Working with an OEM pump manufacturer to design a custom pump may initially be more costly. However, in the long run, choosing a supplier that considers all of the application’s details and requirements will provide the best options, long-term success, and ROI
• OEM: Does the pump supplier have a history of working in the original equipment market? What are their engineering and manufacturing capabilities? Do they outsource their engineering or manufacturing? If so, how do they test for quality? What are their quality standards? What about their performance and life testing practices? Is a company representative avail-able who can address technical questions or are email or the company website the only “discussion” options? These are all important questions when researching a pump supplier.

Traveling supplier? Is the supplier open to visiting an OEM’s facility in order to get a first-hand look at an application? Even though technology allows the world to communicate much easier, nothing beats the “up close and personal” care given by an in-person visit.

• Avoid knock-offs: It is very tempting when working with a tight budget to cut corners on components. While there are many reputable pump suppliers that will take care of an OEM’s needs, there are also many suppliers that create “knock-off” pumps, or cheap copies of pumps sold by legitimate pump manufacturers. These companies are able to sell cheap by using less than standard components or work forces that do not hold to any type of quality standards. In the short term, pumps are more affordable; in the long term, one will find problems with consistency, reliability, and quality.

Understanding the need and importance of a pump in an OEM application is the first step in specifying the correct pump. Specifying a pump early and choosing a reputable supplier will have an important impact on the application’s function, life, and reliability. For more information, visit www.sovoflo.com.

Understanding your own systems flow and pressure requirements is a starting point to choosing the correct pump. Adding a pump to the system also makes an impact. This is another reason that a pump should be specified early on.

When looking for a pump supplier, it is important to understand how the company tests for quality and its quality standards. 

 

 

Methods for Diaphragm Pump Selection

Part 1: Pressure, Vacuum, and Flow

Pressure and Flow

For most sampling applications, the following information is sufficient in determining the type of pump to select:
♦ Required Vacuum
♦ Required Pressure
♦ Sample point conditions
♦ Required Flow Rate
♦ Temperature and Type of Gas being pumped
♦ Ambient temperature where pump will operate
♦ Distance and diameter of tubing
♦ Voltage, frequency, and classification of motor

Vacuum

If the required vacuum is not known, you will need to calculate the pressure drop from the sample point to the pump inlet. SOVOFLO can perform this calculation. What we need to know is the required flow rate, line distance and diameter, Gas composition and temperature and initial pressure at the sample point.

Pressure

If the sample gas is venting to atmosphere downstream, then only the vacuum needs to be calculated. If the gas is returning to a flare or back to process, then the pump will probably require pressure to get there. Again, SOVOFLO can calculate this – however we will need to know the pressure at the return point.

Reading the Curves

♦ The pump curves we provide are really (2) curves plotted onto (1) graph.
♦ The left side of the zero is inlet vacuum vs. flow rate with the assumption that the outlet discharges to atmospheric pressure (or close to it).
♦ The right side of the zero is outlet pressure versus flow rate with the assumption that the inlet pulls from atmospheric pressure (or close to it).
♦ In applications where the pump is pulling a vacuum and providing discharge pressure; we have another set of curves called “combination curves”.
♦ Please contact SOVOFLO in these cases.

Vacuum Example

♦ If the inlet pressure drop is calculated as 5 InHg at 8 SLPM and the sample vents to atmosphere, then all we need to do is find a pump that will provide ≥ 8 LPM at this vacuum. See below.
Methods for Diaphragm Pump Selection


Pressure Example

♦ If the pump is located close to the sample point and the downstream pressure required is 5 PSIG @ 6 LPM, then all we need to do is find a pump that will provide ≥ 6 LPM at this pressure. See below.
Methods for Diaphragm Pump Selection

Pressure and Vacuum Applications

Say an application requires a pump to pull through 200′ of 3/8″ sample line, flow to an analyzer, and then return to a process line 350′ away. In this case, the pump will be required to pull a vacuum on the inlet, provide flow to an analyzer, and provide positive pressure to the process line.
♦ For this we must use what we call “combination curves”.
♦ These curves show a pump’s flow rate at a given vacuum and outlet pressure.

Combination Curve Example

♦ In this case, we need to pull 10 InHg @ 7 LPM to draw the sample, but also provide a discharge pressure of 10 PSIG in order to push the sample back to the process line. See below.
Methods for Diaphragm Pump Selection

Pressure Boosting Applications

In some cases, the process line may be under positive pressure when it reaches the pump inlet. If the gas sample must then be pushed back to a process line, a pump can be used to “boost” the pressure. When the pump inlet pressure exceeds 0 PSIG, the pump performance capabilities (in terms of discharge pressure and flow rate) can increase significantly. It is very important that under these circumstances specific calculations are done by SOVOFLO to avoid oversizing the pump; which can lead to premature diaphragm, bearing, and motor wear. The information we require in these applications (in addition to gas type and temperature) are pump inlet Pressure (PI) , Pump outlet Pressure (PO), and flow rate.
