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 do Diaphragm Compressors Work?

Diaphragm compressors move (and compress) gas using a set of three, flexible diaphragm membranes. Gas enters the compressor’s process head from an external tank or process on its down-stroke. On the up-stroke, the diaphragms flex, reducing the area inside the chamber, pushing the gas out of the compressor (and on to the process/application).

How Do Hydrogen Fuel Cells Work?

What are Hydrogen Fuel Cells?
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.

The Basics: Centrifugal Gas Compressors 101

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.
