How does a pump or HVAC controller know when pressure changes? The answer starts with a small component that gives the system a usable measurement. Once you understand that component, equipment specifications become much easier to read. In this guide, we’ll walk through how it works, where you’ll find it, and what to check before you choose and use one. What Is a Pressure Transducer? A pressure transducer is a component that converts gas or liquid pressure into an electrical signal. …

You may have seen cavitation mentioned in a pump manual or heard it during a discussion about poor performance. It gives you something to investigate, though the term alone tells you little about your particular installation. So, what is cavitation, and where should you start? In this guide, we’ll explain water pump cavitation and the checks that help you understand what needs attention before you change anything. TL;DR Cavitation forms when liquid pressure falls below vapor pressure. Bub …

 If your pump is running but the tap is still dry, switch it off before checking whether it needs priming. The pump chamber needs water before startup, and the filling method depends on the model and water supply.  Today, we'll walk you through the whole process of how to prime a Grundfos pump with separate SCALA2 and CMBE steps. If you have a Grundfos pump for home use, we’ll also show you how to check that it’s supplying water properly. TL;DR Find your model and product …

Grundfos centrifugal pumps work through an electric motor that turns an impeller, transfers energy to water, and creates the pressure difference needed for flow. Grundfos manufactures equipment for several applications, so the unit beside your boiler has a different job from one connected to your household water supply. If you’re asking “how does a Grundfos pump work?” because you’ve spotted one in your home, start with its purpose. Different Grundfos pump models serve he …

A contractor, estimator, engineer, or buyer may find one grooved piping brand listed in the project documents while another is easier to source. That makes the decision more practical than simply comparing two names. Pressure ratings, pipe sizes, coupling construction, gasket options, installation details, and availability can all change the outcome. If you want more background on connection styles, you can also review the different types of pipe couplings in our other guide. But in this guide, …
