Pump Impeller Balancing: When Is It Needed?

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.

Oxygen/CO2 Water Treatment and Its Benefits

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 Pump Working Principle and Uses

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.

Flexible Impeller Pump Advantages & Disadvantages

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.

Solved: Pressure Drop in Industrial Pipe Systems

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 Pump Types Explained

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.

End-Suction vs Inline Pumps: Which To Use?

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.

How Do Pump Check Valves Work?

A pump check valve is a self-actuating, one-way or non-return valve. This automatic safety device allows fluids to flow freely in one direction. However, if the fluid flow is reversed, the valve will automatically close, thus protecting the connected piping and pump.
