Pump & Compressor Insights

Welcome to Sundyne’s blog – our goal is to share information (at varying levels of detail) to provide insight on pumps, compressors and the aftermarket parts & services that can help Sundyne’s customers get more out of their process equipment investments.

How Does a Hydrogen Fuel Cell Work?

Hydrogen fuel cells produce electricity in a similar way that lithium-ion battery cells power electric cars – but Hydrogen fuel cells do not run down or need recharging. Like a battery, a Hydrogen fuel cell consists of two electrodes: a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around a polymer electrolyte membrane. Hydrogen (stored in tanks or reformers) is fed using Sundyne PPI compressors to the anode side of the fuel cell, while oxygen (from the air) is fed to the cathode side. On the anode side, a catalyst (typically platinum) splits hydrogen molecules into protons and electrons. The...

The Basics: Centrifugal Gas Compressors 101

What is a Centrifugal Compressor used for? Centrifugal compressors move gas from point A to point B. They’re also used to increase gas pressures. A good example comes from the power generation industry. In power plants, gas turbines require gas inputs to be approximately 250-750 psig – but interstate pipelines move gas at pressures of just 30-125 psig. In order to run turbines in an optimal fashion, the pressure of the gas inputs must be boosted – and centrifugal compressors are used to do this. How do Centrifugal Gas Compressors work? Centrifugal compressors elevate gas pressure by adding kinetic energy/velocity...
