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](https://blog.hayespump.com/blog/positive-displacement-pump-types) and the pumping action of a [centrifugal pump](https://blog.hayespump.com/blog/centrifugal-pumps-explained). Moreover, the flexible impeller can also create a vacuum inside the pump housing, which helps with self-priming. [![](https://blog.hayespump.com/hubfs/pressure-drop.jpg)](https://blog.hayespump.com/blog/pressure-drop-in-industrial-pipe-systems) ## [Solved: Pressure Drop in Industrial Pipe Systems](https://blog.hayespump.com/blog/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. [![](https://blog.hayespump.com/hubfs/positive-displacement-pumps.jpg)](https://blog.hayespump.com/blog/positive-displacement-pump-types) ## [Positive Displacement Pump Types Explained](https://blog.hayespump.com/blog/positive-displacement-pump-types) 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. [![](https://blog.hayespump.com/hubfs/end-suction-vs-inline-pumps.jpg)](https://blog.hayespump.com/blog/end-suction-vs-inline-pumps) ## [End-Suction vs Inline Pumps: Which To Use?](https://blog.hayespump.com/blog/end-suction-vs-inline-pumps) 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. [![](https://blog.hayespump.com/hubfs/centrifugal-pump-types.jpg)](https://blog.hayespump.com/blog/centrifugal-pump-types) ## [Centrifugal Pump Types and Applications](https://blog.hayespump.com/blog/centrifugal-pump-types) Pumps play a vital role in the ways our world functions today. Industrial pumps, for example, are a part of most manufacturing processes. Commercial pumps ensure that office buildings remain functional for businesses. Similarly, municipal pumps provide fresh water for our cities and clear wastewater from our drainage systems. [![](https://blog.hayespump.com/hubfs/how-do-check-valves-work.jpg)](https://blog.hayespump.com/blog/how-check-valves-work) ## [How Do Pump Check Valves Work?](https://blog.hayespump.com/blog/how-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. [![](https://blog.hayespump.com/hubfs/centrifugal-pump-deadheading.jpg)](https://blog.hayespump.com/blog/centrifugal-pump-deadheading) ## [How to Protect Centrifugal Pumps From Deadheading](https://blog.hayespump.com/blog/centrifugal-pump-deadheading) ## What is Deadheading? A deadhead is when a [centrifugal pump](https://blog.hayespump.com/blog/centrifugal-pumps-explained) 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. [![](https://blog.hayespump.com/hubfs/single-vs-three-phase-pumps.jpg)](https://blog.hayespump.com/blog/single-phase-vs-three-phase-pumps) ## [Single Phase vs Three Phase Pump Configurations](https://blog.hayespump.com/blog/single-phase-vs-three-phase-pumps)   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. [![](https://blog.hayespump.com/hubfs/water-pump-short-cycling.jpg)](https://blog.hayespump.com/blog/water-pump-short-cycling) ## [What Is Water Pump Short Cycling and Why Does it Happen?](https://blog.hayespump.com/blog/water-pump-short-cycling) If your[water pump](https://hayespump.com/products/) keeps turning **on and off rapidly**, you may be dealing with **short cycling**. This common issue not only disrupts water flow but also puts unnecessary stress on your pump, leading to premature wear and costly repairs if left unresolved. [![](https://blog.hayespump.com/hubfs/multistage-pumps.jpg)](https://blog.hayespump.com/blog/what-are-multistage-pumps) ## [Multistage Pumps: What They Are & What They’re Used For](https://blog.hayespump.com/blog/what-are-multistage-pumps) The relative simplicity of design has made [centrifugal pumps](https://blog.hayespump.com/blog/centrifugal-pumps-explained) the most commonly available and widely used pump type in the market. Based on the number of impellers, centrifugal pumps can be classified into two categories - single-stage and multistage.
