What to Know
When choosing a pump, there are many important considerations that need to be made. First up is the flow, or the rate at which the water moves through the pump and is measured in the amount of water per amount of time, typically gallons per minute. Next up is head, which is the vertical distance that the pump needs to move the water. Another key consideration is the spec of the power source, to ensure that the amperage drawn by the pump is sufficient for safe operation. Other concerns include whether the water is clean or dirty, whether solids are present, and if so their density and composition matters too. The major key is to understand the planned application very well before choosing a pump. Today’s focus is going to be on the world of submersible pumps.
Why Submersible Pumps?
One of the biggest advantages with submersible pumps is the ability to pump higher vertically than engine-powered pumps. Primarily, submersible pumps are powered electrically, which allows excellent versatility. With the knowledge of the required flow, head, and power needs, a pump can easily be selected to suit the job. Tsurumi Pump is a global leader in submersible pumps, offering a wide range of pumps for a variety of applications. Unlike competitors’ pumps that are made for intermittent duty, these pumps use a permanent magnetic motor and are designed for continuous duty, able to be left running for extended periods of time and running more efficiently thanks to larger copper wiring inside. Another design feature used to extend the service life of the machines is the ability to automatically shut down as a failsafe to prevent serious damage if they begin to overheat. Their longevity is further bolstered by other innovative design choices, such as the use of anti-wicking cable, with the wiring protected by a strong epoxy seal, as well as durable mechanical seals made from silicon carbide to resist abrasion over long periods of continuous use. On top of these factors, they are also simple to maintain, with many models boasting easy access to the oil reservoir without requiring disassembly. Another major benefit is the use of a channeled “oil-lifter” system, which helps ensure that the mechanical seals are properly lubricated at all times.

Which Pump Do I Need?
As previously mentioned, knowing the application makes all the difference when it comes to choosing a pump. De-watering pumps, for example, must not be used if any solid material is present in the water. For example, an excellent use for de-watering pumps is clearing clean groundwater from a jobsite. De-watering pumps such as the LB-480 and LB-800 by Tsurumi Pump can achieve fantastic flow, and do so with less power strain on a generator than competing pumps. However, if the water being pumped contains any solid matter like grits, leaves, or sand, then a submersible trash pump is the tool for the job. A trash pump like the HS2.4S or HS3.75SL offered by Tsurumi Pump will be able to handle debris, with a volute housing designed to pass solids that are in the water. In addition, many trash pumps in this lineup feature agitators and heavy-duty impellers that keep large solids out while smaller solids pass without clogging the pump. Some trash pumps are designed to push the maximum possible volume at a certain head level, excelling in this task while still being able to tolerate water containing grits or sediments. When selecting a trash pump, considering the media that may appear in the water is critical. Tsurumi Pump’s offerings make this a simple task with the design of their pumps. The bases where water flows into the pumps are carefully designed to only allow solids through that the pump will be able to pass. With the types of pumps in mind, power considerations can be made. Not every 1HP pump is created equal, and the LB and HS lineups can operate more efficiently than competing pumps, getting more out of the horsepower available while using less electricity to generate that power, which can be a lifesaver when using a smaller generator or connecting to shore power that may not have extravagant capabilities. Any job can be tackled with the right pump choice, and thinking about each of these important factors will save time, money, and headache in the long term.
