Those who need to move fluids using centrifugal force, they will quite often select a self-priming pump. With an impeller placed within a large casing, it’s possible to move water even when below the pump. Using centrifugal force, a pumping action is created through the difference in pressure with the liquid. Over time, the liquid is suctioned up into the pump and removed from unwanted locations. What does priming mean? Often, there’s confusion surrounding this term (especially for those without relevant experience in this area). However, priming describes the process of using water or another fluid to fill the intake. Why? Because this displaces air in the system and creates a vacuum. Once the vacuum is created, any water beneath the pump is pulled upwards. After stopping the pump, the important note is that the operator doesn’t need to start from scratch. Instead, a non-return valve activates, and this holds water in the priming chamber. Whenever the operator wants to start pumping again, they simply activate the pump because the chamber is primed for use. So long as there is liquid in the priming chamber, the pump will continue operating.
Applications for Self-Priming Pumps
The difference between self-priming pumps and other designs is that they can remove air when starting up – before starting the normal pumping function, it removes the air and then goes through the process discussed above. In terms of applications, many professionals rely on self-priming pumps in both commercial and industrial settings. For example, this includes people in sewage treatment facilities, steel mills, breweries, power plants, wineries, and more. Why do professionals use this equipment? Here are just some examples:
- Removing water from a boat water pumps or another vessel
- Removing water from a basement after a flood
- Increasing water pressure
- Pumping fuel, raw sewage, water, industrial wastewater, and other fluid
- Transferring liquid from one location to another
- Sewage treatment
- Swimming pool pumps
Benefits of Self-Priming Pumps
When using an advanced piece of machinery like Remko pumps, the first benefit is that the pump is self-priming, and this reduces the maintenance and the task required of professionals. Not only is the machine easier to use, but you simply carry it above ground for maintenance. At no time is any part submerged in fluid, and this makes maintenance much easier than other options. Furthermore, you will find that a range of seal options exist depending on your desired application. For instance, this includes flushed mechanical seals and double mechanical seals. Just in case this isn’t enough, you can also choose between a range of materials. While some require cast iron (this is the most common option), others choose duplex stainless steel, stainless steel, and alternative materials. All in all, you can use the pump for multiple project types, and this is evident in the applications listed in the previous section. While some professionals use self-priming pumps to move water, others need to move waste and other fluids. The design is reliable, robust, and relatively simple, considering the incredible job it performs. After the first priming of the pump, you don’t need to worry about priming because it’s automatic. With no operator input, the pump is always ready for the next task. Before choosing a pump, think about your needs and the project in hand. If you need help, be sure to speak to a specialist because they will provide tailored advice (this will prevent choosing a model that isn’t up to the task).
