Knowing how your pump sounds when it's running healthy can save you a lot of money in the future. Every pump will make a “healthy” free flowing sound as a medium is passed through it unimpeded. A rhythmic vibration should be produced by the motor. By familiarising yourself with these sounds, you can quickly identify when something is wrong, a change of sound is a a great indicator that there is a problem somewhere. This will allow you to take the correct course of action, and could save you a fortune in future maintenance or replacement costs. Let's take a look at the kind of sounds you might encounter, and talk about the most common culprit – cavitation. What is Cavitation? Cavitation is a problem which results in damage to equipment. It occurs during low pressure and can also be found in pump systems with high vacuum conditions. This happens when there is reduced or impeded flow, which is usually a symptom that a pump isn’t working properly or is not suitable for transportin...

It's important that you know the flow rate of your system. Flow rate is how much fluid you can transport within a given time. Knowing this helps you achieve two critical things: You can assess if an existing system isn't working efficiently. If you know the flow rate you should be achieving and yet your system is not performing, then you can take the necessary action. You can determine the exact set-up you will need to transport, at the volume you require.  Calculating Flow Rate During Planning Stages Determining the flow rate you will need is an essential part of planning your system design, before you go ahead and order or install your new pump. If you get this wrong, then you might have to invest money in replacement equipment which could seriously impact your budget. ​ The equipment most suited to your specific needs will be reliant on three things: The type of fluid you need to pump The distance it has to travel from point A to point B The volume of fl...

Friction can significantly impair your pump's performance. It can reduce your head pressure to such a degree that it can be impossible to transport a fluid efficiently. More than this, friction itself can actually damage your pump, valves, and piping, if the equipment you are using hasn't been specifically designed to handle abrasive substances. With this in mind, let's take a look at how to calculate friction so that you can better understand how it will affect your head pressure and equipment. Defining Friction Friction is simply the resistance between two touching surfaces when at least one surface is moving. In this case, the piping of your system is stationary but the fluid you are  pumping  is moving. Friction Loss and Head PressureThe amount of head pressure which is lost due to friction is often called “friction loss”, and this is a critical part of choosing necessary equipment. It is also an essential part of setting the power level of your pump. The h...

Cavitation is a common problem for centrifugal pumps. If you hear strange noises coming from your  pump  there’s a good chance cavitation is the issue. But what exactly is cavitation? And how can you go about preventing it? Read on to find out. What is Pump Cavitation? To understand how to prevent pump cavitation, it’s important to have a good understanding of what the problem is and how it arises. There are several types of cavitation which we’ll discuss below, but the process is similar.  Cavitation Defined:  Cavitation is the formation and accumulation of bubbles around a  pump  impeller. This tends to form in liquids of any viscosity as they are being transported through and around a pump system. When each of these tiny bubbles collapses or bursts, it creates a high energy shock wave inside the liquid. Imagine throwing a stone into a pond. The circular ripples which are created in this process are similar to cavitation bubbles exploding. The difference...

A hot water recirculation system is a plumbing system that moves hot water to fixtures quickly without waiting for the water to get hot. Rather than relying on low water pressure, common in most water lines, recirculating systems rapidly move water from a water heater to the fixtures.   System Types  dedicated loop:  The  circulation pump  for this system is mounted on a pipe connected to the water heater tank down low. This is the cooler side of the loop, or the return. The hot water pipe is installed in a loop throughout the home, passing near each plumbing fixture. At each fixture, a short pipe connects the loop to the hot water valve. Because hot water is constantly circulating through the hot water loop, any time a valve is opened, it takes only a fraction of a second for hot water to reach the valve. This helps extend the lifespan of the  pump . If the home is not occupied, this pump will be probably be unplugged because ...

A domestic hot water (DHW) recirculation system can do that as well as prevent lukewarm water from being dumped down the drain by bypassing it into the cold water line. This process saves water, utility costs, and energy and sewer expenses. It also helps reduce the fresh water shortage. Water savings are hard to calculate because of so many influencing factors. A study estimates water savings of up to 12,000 gallons for four points of hot water use and up to 15,000 gallons for five points of use per year. The savings also depend on the size of the pipes (1/2-inch,  ¾- inch or 1-inch copper or PEX), total length of pipe from the heater to the furthest sink, size of the  pump  and efficiency of the system. The selection of the correct hardware, controls and  pump  are important for long service life. Payback depends on the cost of the monthly water utility bill, electricity cost per kW, how many users are in a home, and initial installation cost, though it is typ...
