Flue gas from thermal power, metallurgy, chemical, cement and other industries contains large quantities of SO₂. The wet flue gas desulfurization system (FGD) is standard equipment for emission compliance, energy conservation and carbon reduction. As the core power equipment of FGD, desulfurization pumps deliver corrosive solid-containing slurry and directly determine desulfurization efficiency and system stability.

Chemical production involves complex working conditions. Factors such as corrosion, temperature and pressure fluctuations, and explosion-proof requirements impose vastly different demands on the performance, materials and structures of chemical pumps. Improper pump selection may lead to pump damage, leakage, low efficiency, as well as production line shutdowns, safety hazards and material losses, which are common pitfalls in the procurement, operation and maintenance of chemical equipment. Many industry practitioners struggle to match pump models to special working conditions. Combined with widely used industrial scenarios, Omron Tech Pumps explains pump selection methods, applicable models and key precautions for different working conditions, delivering highly practical content that can serve as a direct reference for pump selection.

Thermal fluid hot oil pumps are core gear for steel hot working. They circulate high-temp heat transfer fluid to deliver steady heat for tempering, quenching, galvanizing, heat treatment and rolling preheating, securing steel quality and continuous production. Built for steel mills’ high heat, dust and heavy vibration, they cut breakdowns and maintenance costs as essential production supporting units.

Omron Tech Pumps chemical pipeline pumps are vertical fluid transportation equipment specially used in chemical, petrochemical, pharmaceutical, environmental protection, water treatment and other industries. Featuring direct pipeline mounting structure, stable operation, corrosion resistance and easy maintenance, they serve as core equipment for transporting corrosive, high-temperature and high-pressure media in chemical production lines. Different from ordinary water pumps, chemical pipeline pumps boast sophisticated structures and strong working condition adaptability, enabling long-term continuous operation and effectively ensuring the safety and efficient operation of chemical fluid transportation systems. This paper comprehensively analyzes the core characteristics of chemical pipeline pumps from equipment classification, core structures, operating performance and operation & maintenance key points.

Screw pumps are common positive displacement conveying equipment, mainly divided into cast iron screw pumps and stainless steel screw pumps. Featuring high head, stable operation, low shear force and strong adaptability, they excel at transporting high-viscosity fluids, particle-laden media, long-fiber materials and easily precipitating slurries, effectively making up for the drawbacks of centrifugal pumps such as easy clogging and poor wear resistance. With reliable performance, screw pumps are widely adopted in numerous industrial sectors including petrochemicals, environmental protection, food, pharmaceuticals, mining and shipbuilding, serving as core equipment for transporting complex fluids.

n pump type selection and operation & maintenance, many users hold misunderstandings: they mistakenly believe that the lower the actual operating head of a pump, the lighter the motor load and the less likely the motor is to burn out. For this reason, many users deliberately select high-head centrifugal pumps with rated heads far exceeding working condition requirements, assuming a larger head margin ensures more stable operation.

In modern industrial production such as chemical processing, water treatment, electroplating and pharmaceutical manufacturing, the transportation of corrosive, high-purity and scaling-prone fluids imposes extremely high requirements on pump equipment. Traditional cast iron and stainless steel pumps are prone to corrosion, metal impurity precipitation and high operation and maintenance costs, making them difficult to adapt to complex working conditions. Manufactured from engineering plastics including PP, FRPP, PVDF and PTFE, plastic pumps have become mainstream equipment for industrial fluid transportation and widely replace traditional metal pumps due to their stable chemical properties and cost performance.

End-suction pumps and inline pumps are the two most widely used pump models. Many engineers and procurement staff struggle to distinguish their applicable working conditions, performance differences, advantages and disadvantages during model selection. This article comprehensively compares the two pumps from structural design, performance characteristics, pros and cons, applicable scenarios, cost and maintenance dimensions to help you select the optimal model accurately.

Split casing pumps (split case pumps, split casing centrifugal pumps) are core fluid transportation equipment for industrial and civil applications. Featuring splittable pump casings, large flow rates, high stability and easy maintenance, they are widely adopted in municipal engineering, fire protection, heating ventilation and air conditioning (HVAC), power generation, chemical industry, agriculture and other sectors, serving as the preferred pump type for 24-hour continuous water conveyance conditions. This guide systematically sorts out core knowledge of split casing pumps to facilitate rapid model selection, standardized operation and maintenance.

Water pump vibration, noise, pipeline shaking and building resonance are mainly caused by substandard installation and vibration isolation failure. Vibration isolation is a core installation process rather than an optional noise reduction step. Standard installation effectively blocks vibration transmission between pumps, pipelines and building structures, avoiding pipeline cracking and structural resonance, extending pump service life and ensuring stable water supply system operation.
