Why Mechanical Dosing Pumps Still Matter in Modern Process Systems Accurate chemical dosing remains a foundational requirement across industrial, municipal, and utility processes. From corrosion control and water treatment to chemical conditioning, consistent injection rates directly influence process stability, compliance, and equipment protection. While automation and digital control continue to …
Why Digital Dosing Pumps Matter in Modern Process Control Digital dosing pumps are precision chemical metering devices that deliver highly accurate, repeatable dosing under varying operating conditions. They combine the mechanical reliability of positive-displacement pumps with microprocessor-based control, enabling real-time verification, adjustment, and optimization of chemical feed rates. In applications …
Sealless magnetic drive pumps represent a critical technology in process industries where leakage, emissions, and maintenance risk must be minimized. By eliminating dynamic shaft seals, traditionally the most failure-prone component in rotating equipment, sealless mag drive pumps significantly reduce downtime, improve safety, and support compliance with increasingly stringent environmental regulations. …
An air-operated diaphragm pump (AODD) is a seal-less, positive-displacement pump that uses compressed air to drive flexible diaphragms and move fluid without rotating components. This design enables reliable handling of abrasive slurries, viscous fluids, corrosive chemicals, and solids-laden media while offering self-priming, dry-run tolerance, and inherent leak containment. These …
A visual “field guide” to the core pump categories that keep crude distillation units moving—matching pump types to refinery duties, operating severity, and hydrocarbon behavior.
Crude oil distillation is the central refining process that separates hydrocarbons into distinct fractions, such as gasoline, diesel, jet fuel, gas oils, and heavier residues, according to their boiling points. This process relies heavily on robust fluid handling to move raw crude, intermediate streams, and end products through heaters, towers, …
Catalytic cracking units operate at extreme temperatures, circulate abrasive catalyst-laden fluids, and rely on continuous, stable flow to support refinery throughput. Every pump connected to this process must withstand high thermal loads, erosive service conditions, and volatile hydrocarbons while maintaining predictable performance over multi-year operating cycles. Understanding which pumps are …
Hydroprocessing is central to producing cleaner, higher-value fuels, and the pumps that support these units operate under some of the harshest conditions found in refining. Hydrotreaters and hydrocrackers depend on precise, high-pressure circulation of feedstock, hydrogen-rich gas, and catalyst-laden streams to maintain efficiency and reaction stability. Understanding pump requirements for …
A “where they live and what they move” infographic that connects key FCC support flows to the pump types that keep conversion and fractionation stable.
Maintaining a stable temperature difference (ΔT) across heat exchangers is essential for efficient industrial heating and cooling loops. When flow rates fluctuate or loads shift, that temperature difference can widen or collapse, leading to poor heat transfer, equipment stress, higher energy use, and uneven process performance. Variable-speed drives (VSDs) provide …
