Understanding Your Needs

First things first, you need to figure out exactly what you'll be using the pump for. Are you looking to drain a flooded basement? Maybe you need to transfer water from one place to another on a construction site? Or perhaps you're dealing with oil transfer in an industrial setting. The intended use of the pump will be the primary factor in determining the right model for you.

For example, if you're just dealing with clean water, a basic Mobile Self-priming Pump might be sufficient. These pumps are great for general water transfer tasks like emptying a pool or draining a small pond. They're usually easy to operate and relatively affordable.

On the other hand, if you're working with oil, you'll need a Self-priming Oil Pump. These pumps are designed to handle the specific properties of oil, such as its viscosity and flammability. They have special seals and materials that can withstand the harsh conditions associated with oil transfer.

Flow Rate and Head

Once you've determined the type of fluid you'll be pumping, you need to consider the flow rate and head. The flow rate is the amount of fluid the pump can move in a given amount of time, usually measured in gallons per minute (GPM) or liters per minute (LPM). The head is the height or pressure that the pump can lift the fluid against.

Let's say you're trying to pump water from a well to a storage tank on a hill. You'll need a pump with a high enough head to overcome the elevation difference. At the same time, you'll also need a sufficient flow rate to fill the tank in a reasonable amount of time.

To calculate the required flow rate and head, you'll need to know the distance the fluid needs to travel, the elevation change, and the diameter of the piping. There are some online calculators that can help you with these calculations, or you can consult with a professional.

Power Source

Another important factor to consider is the power source. Mobile self-priming pumps can be powered by electricity, gasoline, diesel, or even solar energy. Each power source has its own advantages and disadvantages.

Electric pumps are usually the most convenient and cost-effective option for small-scale applications. They're easy to start and operate, and they don't produce any emissions. However, they require a reliable power source, which can be a problem if you're working in a remote location.

Gasoline and diesel pumps are more powerful and can be used in areas where electricity is not available. They're also more portable, which makes them a popular choice for construction sites and other outdoor applications. However, they require regular maintenance and produce emissions, so you'll need to take these factors into account.

Solar-powered pumps are a great option if you're looking for an environmentally friendly and cost-effective solution. They're powered by the sun, so you don't have to worry about fuel costs or emissions. However, they're usually less powerful than other types of pumps, and they may not be suitable for all applications.

Construction and Durability

The construction and durability of the pump are also important considerations. You want a pump that can withstand the harsh conditions of your application and last for a long time.

Look for pumps that are made from high-quality materials, such as stainless steel or cast iron. These materials are corrosion-resistant and can handle the wear and tear of regular use. You should also consider the design of the pump, including the impeller, casing, and seals. A well-designed pump will be more efficient and reliable.

Noise Level

If you're using the pump in a residential area or a noise-sensitive environment, you'll want to consider the noise level. Some pumps can be quite loud, which can be a nuisance to you and your neighbors.

Look for pumps that are designed to operate quietly. Some manufacturers offer pumps with noise-reducing features, such as soundproof enclosures or vibration dampeners. You can also choose a pump with a lower horsepower, as these pumps tend to be quieter.

Cost

Of course, cost is always a factor when making a purchasing decision. You'll want to find a pump that fits your budget without sacrificing quality or performance.

Compare the prices of different pumps from various manufacturers. Keep in mind that the cheapest pump may not always be the best option. You'll also need to consider the long-term costs, such as maintenance and repair expenses.

Brand and Reputation

Finally, you should consider the brand and reputation of the manufacturer. A well-established brand with a good reputation is more likely to produce high-quality pumps that are reliable and durable.

Read reviews and testimonials from other customers to get an idea of the manufacturer's reputation. You can also ask for recommendations from friends, colleagues, or industry professionals.

Conclusion

Choosing the right mobile self-priming pump for your needs can be a challenging task, but it doesn't have to be. By considering the factors outlined above, you can narrow down your options and find a pump that meets your requirements.

You need to know the weight of the fluid to ensure the pump has enough power to draw the liquid through. In many cases, we find different fluid types at the very same construction site. Sludge, construction materials and other insoluble materials, often ranging in size from particulates to solids of up to 4”, must be pumped along with the fluid.

The pH level is also essential to understand the fluid. It measures how acidic/basic the water is. The range goes from 0 to 14, with 7 being neutral. pH level’s of less than 7 indicate acidity, whereas a pH greater than 7 indicates a base. The further you deviate from the neutral 7, the more chemical impact the fluid will have on the pump internal components. The correct material selection of the pump internals is the key to combat this challenge and keep the pump away from any malfunction. 

In short, make sure that the pump you choose is designed to move the type of fluid you are facing. For instance, using a centrifugal trash pump to dewater heavy slurry will end in a damaged pump.

Most pumps are trailer-mounted or skid-mounted. A trailer-mounted pump system is easy to transport but may take up additional space on the jobsite. Also, if there is not a power source nearby, an electric pump will not suit your needs. 

If you are pumping up-hill, static discharge head becomes a critical factor, being the height of the source of the fluid you are pumping to the height of its destination. There are formulas that you can use to determine what pump you need based on the elevation, the lift needed, and the distance the fluid must travel. For every ten feet you pump uphill, you lose 4 PSI (Pounds per Sqaure Inch), which means you must give more consideration to the pump pressure capability when selecting your pump. This is where the pump’s performance curve comes in handy.

Every pump comes with its own performance curve chart, which tells you how much volume over time a pump moves under a given pressure rating. The volume over time is measured in l/s or m3/h or GPMs (gallons per minute) and the chart will tell you what the pump’s flow rate is as a certain pump outlet pressure. This is what we call the pump duty point or operating pump point. 

Based on application criteria such as distance of fluid travelling, elevation to overcome and desired flow rate, the pump duty point is going to vary. Why is all this important? Chances are your application is time contingent, meaning you have a certain amount of time to get the fluid from Point A to Point B. If your pump doesn’t supply you with the flow rate needed to move the fluid when and where it needs to in the time you have, then your job doesn’t get done the way it should. Not good.

What’s the best advice we can give, all of the above considered?  Seek professional help when choosing a dewatering pump.
