Chemical production processes are highly complex, with core equipment such as reaction vessels, process pipelines, heat exchangers, and storage tanks and silos exposed for extended periods to acidic and alkaline media, heavy oils, and crystallizing materials. This exposure readily leads to the formation of hard scale, coking residues, corrosive deposits, and thick oil sludge. Such contaminants pose significant risks in chemical manufacturing: they can clog pipelines, reduce heattransfer and thermalconductivity efficiency, and result in productivity losses; moreover, they accelerate corrosion and aging of equipment substrates. Over time, accumulated fouling may trigger equipment failures and pressure anomalies, compromising both operational stability and safety. Consequently, routine, professional equipment cleaning and maintenance is a critical component of safe production and costreduction efforts in the chemical industry. Highpressure waterjet cleaning, with its advantages of safety, environmental friendliness, nondestructive treatment, and thorough removal, has become the mainstream technology in the chemicalcleaning sector, while highpressure plunger pumps serve as the core power units driving this process.

In actual cleaning operations at chemical plants, the 110liter/1,400kg and 80liter/2,000kg configurations represent the two most widely adopted standard parameter sets in the industry. These can be flexibly switched based on the type of fouling and the structural characteristics of the equipment, ensuring comprehensive compatibility with a wide range of onsite cleaning scenarios. Unlike singleparameter machines, which are limited in their versatility, these two parameterbased models complement each other effectively, addressing both largearea routine cleaning and precision deepscale removal needs, thereby perfectly aligning with the chemical industry’s diverse maintenance and operational standards.

Chemicalindustry cleaning scenarios can be categorized into two primary types of core operational needs, each suited to equipment with different performance parameters. For routine cleaning tasks involving large surfaces—such as tank exteriors, the shells of major equipment, and general plantwide pipelines—highflow models deliver broadarea, rapid flushing, efficiently removing loose rust, loosely adherent deposits, and surface sludge, thereby significantly boosting the efficiency of daily facility maintenance and upkeep. These models are ideal for enterprises’ regular, cyclical preventive maintenance. In contrast, for critical equipment with intricate geometries and stubborn, tenacious fouling—such as heatexchanger tube bundles, confined process lines, and reactor inner walls—highpressure units leverage their powerful penetrating capability to precisely break down and strip away longaccumulated, dense hard scale and carbonized layers. While thoroughly eliminating contaminants, they avoid abrading or scratching the underlying material, meeting the stringent cleaning requirements of major overhauls and indepth inspections in the chemicalprocessing sector.

High-pressure plunger pumps tailored for chemicalprocess applications effectively reduce pressure pulsations during operation, ensuring a continuous and stable highpressure water flow that meets the demands of longterm, continuous operation in chemical equipment. The entire unit is constructed from corrosionresistant materials and features a highstrength mechanical seal design, enabling it to withstand the harsh conditions typical of chemical plants—high humidity and exposure to corrosive media—while complying with explosionproof and durableoperation safety standards. Compared with conventional acidbase chemical cleaning, highpressure waterjet cleaning employs pure water throughout the process, leaving no chemical residues or secondary pollution, causing no corrosive damage to chemical equipment, and eliminating the risk of wastewater contamination, thereby aligning more closely with the modern chemical industry’s commitment to green production.

In summary, high-pressure plunger pumps, with their strong adaptability, stable operation, and efficient, safe cleaning performance, leverage industrystandardized parameter configurations to comprehensively address all cleaning needs in chemical plants—ranging from routine maintenance and in-depth overhauls to equipment refurbishment. They effectively tackle key industry challenges such as scaling, blockages, corrosion, and aging of chemical equipment, ensuring the safe and reliable operation of production lines, while also helping enterprises reduce operational and maintenance costs and achieve green, sustainable production. As such, they are an indispensable core piece of auxiliary equipment in the modern chemicalcleaning sector.
