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.

What is a Hydrogen Compressor?

Hydrogen is a versatile energy carrier. It is one of the most efficient fuels on Earth, with the highest energy content per weight. Hydrogen can be stored for extended periods of time, making it a valuable complement to other renewable sources in the electricity system.

Hydrogen can be produced from almost all energy resources. A color code system identifies the different means:

The Benefits of Low Flow High Head Centrifugal Pumps

When it comes to pumps, the term “head” refers to the height a pump will push liquid up into the air. A high-head pump produces more pressure and will push liquid up further – whereas a medium head pump has more flow, but less pressure and therefore will not push the liquid as high.

Low flow high head capability in centrifugal pumps is required in many critical applications in the hydrocarbon, petrochemical, chemical, power generation, gas production, and specialty processing industries.

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.
