In the comprehensive guide, we will delve into how self-priming pumps (including positive displacement pump setups) work. We will also explore their benefits and diverse applications. If you are looking to buy self-priming pumps, do visit the DAE Pumps website.
Self-priming centrifugal pumps feature a dedicated priming chamber positioned above the impeller. When the pump starts, it draws in a mixture of air and liquid into the pump casing. Here, the centrifugal force generated by the impeller effectively separates the air from the liquid, ensuring the proper functioning of the self-priming pump. Positive displacement pumps like liquid ring pump models are commonly self priming because their smaller clearances allow for easy vacuum creation.
In a self-priming positive displacement pump (including diaphragm pumps), the priming cycle refers to the process by which the pump evacuates air bubbles from its casing and suction line, replacing it with the pumped fluid (usually water) to create a vacuum and initiate the pumping action.
The liquid component, devoid of the constant presence of air or gases, is forced by the impeller to recirculate within the priming chamber. This recirculation creates partial vacuum within the chamber, facilitating the priming of the pump and enabling a smooth flow of the liquid from the suction line.
Simultaneously, the air bubbles are directed towards the discharge sides of the pump. This allows for the efficient expulsion of air, ensuring that the pump is fully primed and ready for optimal performance.
Once the priming cycle is complete and the pump is fully primed, it operates in the same manner as a conventional centrifugal pump, drawing fluid into the suction line and discharging it through the pump discharge port to a storage vessel.
Understanding how self-priming pumps work enables us to appreciate their efficiency and reliability in various applications, high and low pressure.

The time it takes for a self priming centrifugal pump to prime can vary depending on factors such as pump size, suction pipe length, and the presence of all the air in the system. In general, such pumps are designed to prime quickly, typically within a few seconds to a couple of minutes, ensuring efficient operation and smooth flow from the suction and discharge sides.
A self-priming pump is designed to handle fluids that contain suspended solids or air pockets, which reduces the need for maintenance. However, pumps require regular maintenance to ensure that the pumping process offers peak efficiency. Maintenance tasks may include cleaning the pump’s impeller, examining the check valve, checking the suction line for clogs, and inspecting the pump body for signs of wear or damage. Cleaning the suction side, discharge port and process lines can also be beneficial. Here is a quick troubleshoot guide to fix common pump problems.
Self-priming pumps have the ability to operate for short periods without liquid, but it is not recommended to run them dry for extended periods. Running a self-priming pump without liquid flow can cause excessive heat buildup, leading to damage to the pump components, such as the impeller and seal.
The choice between a self-priming pump and a self priming centrifugal pump depends on the application. Self-priming pumps are for frequent priming or where intermittent operation is required, whereas centrifugal pumps excel in continuous operation and handling larger volumes of fluid.

Self-priming pumps for transferring slurry, dredging, dewatering, and other harsh applications are industrial strength to provide continual suction and long-lasting use. DAE pumps make affordable heavy-duty self-priming pumps that move debris with ease, ensuring hassle-free operation. The self-priming pumps draw liquids, solids, and other material from lakes, wetlands, sewers, construction sites, and other flooded areas to the pump where it then transfers everything to a designated area.
Initial priming is crucial for self-priming pumps to operate efficiently. Once the pump achieves its initial priming, it can automatically maintain its priming capability, ensuring reliable performance in various applications (particularly with process style pumps like liquid ring pump models or).
The DAE Pumps self priming centrifugal pumps outperform other conventional self-priming pumps in dewatering applications. A major issue with most self-priming water pumps (or even standard centrifugal pumps) when dewatering is the suctioning of mud and rock that will destroy the pump in a run dry situation caused by intermittent pumping operations. However, self priming centrifugal pumps by DAE Pumps are unphased as they have no issues processing the muck, corrosive liquids or suspended solids while preserving the constant presence of powerful suction.

Self-priming pumps (including our variety of positive displacement pump models) are used for a variety of applications and are one of the most popular types of pumps because of their robust nature. Positive displacement pumps are a type of self-priming pump known for their unique features and capabilities, such as handling varying viscosities and pressures efficiently. They get used in many different scenarios and for many purposes. DAE Pumps self-priming pumps are called industrial water pumps, slurry pumps, booster pumps, transfer pumps, jet pumps, dewatering pumps, surface pumps, process pumps, along with other identifiers because of the variety of applications. Sometimes these pumps are categorized for very similar purposes, but they do distinctly different functions.
One of the simplest uses for the centrifugal self-priming pump is a water pump. The suction pipe plays a crucial role in ensuring efficient pump operation by affecting factors such as priming distance, priming time, and potential challenges like vortexing or cavitation. The purpose of the self-priming water pump is just that, to pump water. Standard water pumps only move water, but when particles, rocks, mud, or other element get mixed in, they clog and wear down very fast. You can find water pumps in vehicles, residential pools, and other light-duty applications but the DAE Pumps industrial self-priming water pumps are capable of pumping water with abrasive solids mixtures of rocks, sand, twine, and other slurries. These reliable industrial water pumps are fire pumps, dewatering pumps at construction sites, irrigation pumps on farms, and for wastewater applications to clean tanks and containers.
A robust self-priming pump that pumps more than just water is called a slurry pump. Liquid ring pumps operate by using a rotating impeller that creates a vacuum and forms a cylindrical ring of liquid that seals the pump, making them efficient in handling various products, including those with entrained air. Slurry pumps move materials with viscosities up to 70% with the primary intent of moving solids over fluids. Slurry can consist of a variety of materials like mud, rocks, sand, food, vegetation, ropes, waste, tires, and anything else that can dirty up water.
DAE Pumps makes a variety of heavy-duty slurry pumps that are self-priming and can transfer large amounts of debris. Our size selection of self-priming slurry pumps meets the highest industry standards in durable metal hardness and volume pumping capabilities. DAE Pumps slurry pumps are used at mining and construction sites, on farms, at wastewater treatment plants, by a variety of city municipalities, in food processing, and a slue of other industries for several applications.
Booster pumps are additional self-priming pumps used to extend the length of pumping capabilities. Pumps can move fluids at a certain distance and height, called the head. The amount of material it can move at the max head is called the max capacity. Once reaching the max head, the flow capacity drops off, so a second, third, fourth, or infinite number of additional pumps may be needed to get to the final destination. These extra pumps are booster pumps. Requiring multiple booster pumps is common in pumping when needing to reach extended lengths and heights. DAE Pumps can help you set-up complete pump systems with any amount of booster pumps you need.
DAE Pumps self-priming pumps make an excellent dewatering pump used for removing water from the soil. Dewatering pumps get used at wellpoints and deep wells for suctioning underground water at the water table, removing floodwater caused by heavy rain, as bypasses for pipe breaks, and other applications. Dewatering of an excavated area is necessary for keeping the bottom dry and prevent leakage of groundwater, as well as rainwater and earth into the excavation. Self-priming pumps are ideal for their portability when mounted to a trailer. These types of dewatering pumps are moved from location to locations as multi-application tools, in emergencies, and for quick access.
A pump curve is a graphical representation of a pumps flowrate against a certain level of head. Using a pump curve that is accurate for your application will greatly help in selecting the correct pump, ultimately saving you time and money.
Pump curves are developed from data gathered during testing of the pumps performance at the manufacturer’s facility and provides the end-user with a graph of how the pump will operate over a set range. To build the pump curve, our engineers compile several variables including type of material, fluid viscosity, distance to pump, target GPM, and factors that are job-specific. This ensures the most efficient pump is recommended for your project.
