Canned motors and magnetic drive pumps fall into the category of seal-less pumps. Seal-less pumps replace the conventional mechanical seal with a static containment shell. The advantage of such a system is that it ensures no fluid leakage. Hence, seal-less motors are the preferred choice when you need to pump fluids that should not leak out in the atmosphere.
Pump impeller balancing is not a term that you’d frequently hear when dealing with pump repairs. However, when it does pop up, it usually means a tedious job of restoring the efficiency of a pump to its original performance. Let’s find out what pump impeller balancing is, why it’s needed and how to perform pump impeller balancing.
Wastewater from industries is a major hazard to the environment. According to a UN water report, 80% of all wastewater flows back to water resources without being treated. This is one of the reasons why many countries mandate industries to treat wastewater sufficiently before it's released.
Mixed flow pumps are the lesser-known variants of centrifugal pumps with the addition of a mixed flow impeller. The fluid flow within these pumps undergoes both axial and radial pumping action. Although these pumps are less common in residential applications, they are a staple in many industrial applications. Read on to find out how mixed flow pumps work, their applications, and their pros and cons.
As the name suggests, flexible impeller pumps have impellers and vanes that are flexible. These pumps use flexible rubber that undergoes deformation when spinning. This unique rubber impeller design also offers the self-priming capabilities of a positive displacement pump and the pumping action of a centrifugal pump. Moreover, the flexible impeller can also create a vacuum inside the pump housing, which helps with self-priming.
Pump systems play a major role in transporting fluids for industrial applications. Being subjected to different fluids, temperatures, and pressures, they are bound to undergo degradation.
Pressure drop is a common issue plaguing industrial pumps with many possible causes. Below we'll dive into some of the main reasons why pressure drop occurs as well as how to fix it.
Positive displacement pumps are the type of pumps that lift a specific fluid volume during each cycle of their operation. The pumping action of these pumps is cyclic in nature, usually driven by screws, pistons, rollers, gears, vanes, or diaphragms.
A pump moves fluid from one location to another. However, there are several types of pumps that you can use to meet your fluid transportation requirements. How do you choose the correct one? Usually, this is where the discussion between end-suction pumps and inline pumps begins.
A deadhead is when a centrifugal pump continues operating without any fluid flowing through the pump. Deadheading results primarily due to a closed discharge valve, line blockage, or if the check valve remains in a seated position.
When selecting a pump for your specific fluid transportation requirements, you’ll likely come across the terms single-phase and three-phase. These are nothing but power phases used by pumps for their operations. To understand which pump to select for your specific applications, let’s learn more about the two power configurations.
