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.

Propylene Pumps - Everything You Need To Know

Polypropylene material is commonly used for the manufacturing of automotive components, profiles, fashion apparel, and healthcare devices. Polypropylene is a thermoplastic resin made from the polymerization of propylene. In the production of polypropylene, propylene monomer is subjected to heat and pressure in the presence of a catalyst system. Polymerization conditions, such as temperature, pressure and reactant concentrations, are set by the polymer grade to be produced.

Pumps for Biodiesel & Renewable Diesel

According to Industrial Info Resources (IIR), US refineries in April made more than 1.5 million barrels of diesel fuel each day. As a comparison, approximately 8.5 million barrels of gasoline were refined per day in the US during the same period. During the pandemic, Shell, Marathon and Phillips-66 closed 11 refineries in the United States. Today, 8 of these 11 plants are being modernized. Some plants will restart traditional operations. Others will be converted to oil export terminals, and more than half of these shuttered plants are being upgraded and converted to process renewables, such as biodiesel and renewable diesel.

What is a Petrochemical Pump?

Petrochemicals are a specific set of organic chemical compounds that are mainly derived from oil & gas, via hydrocarbon cracking and chemical processing. Petrochemical processing plants are located close to (or integrated within) oil refineries, to take advantage of feedstocks, which are typically ethylene, propylene, methanol, hydrogen and aromatic hydrocarbons. Petrochemical feedstocks are used to generate thousands of polymeric chemicals for industrial and consumer use.

How Does A Boiler Feed Pump Work?

Boilers heat water to make steam. Steam is used to heat buildings (via radiators) and it’s also used to make power via steam turbines. High pressure steam performs the mechanical work that turns steam turbines. Every power plant (from large utilities to smaller co-gen plants in universities, hospitals or industrial buildings) has an optimal steam velocity for its process. Water can flow through piping at velocities of 15 to 25 feet/second – but steam line velocities can range as high as 400 feet/second. The boiler feed pump is the heart of the process, because it keeps water flowing into the...

Benefits of an Industrial-Grade Pump

This article identifies areas where Sunflo industrial grade pumps can be deployed, and it also highlights the benefits of using a Sunflo pump in specific areas versus an API-610 pump. What are the different types of pumps and their industrial applications? Pumps move liquid (while compressors move gas). Pumps play a critical role in industrial applications, such as manufacturing, food & beverage processing, mining, chemical processing, power generation, and in the energy industries such as oil & gas production and refining. What are the most common process pump types? The most common types of process pumps are typically API 610...

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: Grey Hydrogen – is produced by steam reforming of natural gas. Today, this is the most common process. Blue Hydrogen – comes from the same process, but the resulting CO2emissions are captured and stored (CCS). Green Hydrogen – is produced by...

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. Sundyne makes Low Flow High Head Pumps in two main configurations: Vertical Low Flow High Head Pumps – are used...

How do Diaphragm Compressors Work?

What is a diaphragm compressor? 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). The oscillating movement of the diaphragms is driven by a reciprocating piston and crankshaft mechanism. Only the process diaphragm and the compressor’s process head come in contact with the gas. This is important because the diaphragms prevent hydraulic fluid (or oil from...

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. Process for Hydrogen Fuel Cells 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...

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...
