In the field of mechanical seal flushing technology, PLAN 11 is the most widely adopted and fundamental self-flushing arrangement. Featuring a compact structure, low cost and convenient maintenance, it has become the standard configuration for single mechanical seals under general operating conditio...

In industrial processes such as coal chemical engineering, petroleum refining, pesticide and pharmaceutical intermediates, printing and dyeing, and seawater utilization, the production of high-concentration saline wastewater is increasing day by day. Such wastewater usually contains high concentrati...

In the industrial scenario of alkali liquid transportation, the selection of pump body material directly determines the service life, operational safety and comprehensive operation and maintenance cost of the equipment. Alkali liquids (such as sodium hydroxide, potassium hydroxide, ammonia water, et...

Hydrofluoric acid (HF), an indispensable basic raw material in industries such as chemical engineering, electronics, and electroplating, is highly corrosive, extremely toxic, and volatile. The safety and stability of its transport process have always been the core pain points in chemical production....

As a major industrial water consumer, the printing and dyeing industry produces 100–200 tons of wastewater for every ton of textiles dyed and printed. This wastewater accounts for about 80% of China’s total industrial wastewater discharge, making it one of the typical types of industrial wastewater ...

In chemical production, chemical pumps act as the core power source for fluid transportation, and the flow rate selection directly determines the system efficiency and operational safety. To avoid the risks of working condition fluctuations, many engineers intentionally set an increased safety margi...

In industrial fields such as chemical engineering, pharmaceuticals, and environmental protection, magnetic pumps have become core equipment for conveying flammable, explosive, highly toxic, and valuable media, thanks to their leak-free, safe, and reliable performance. However, in actual working cond...

As the core document for characterizing the performance of chemical pumps, the performance curve diagram intuitively reflects the correlation characteristics of the pump's operating parameters under different working conditions, and serves as the fundamental basis for pump type selection, operating ...

Every chemical pump must undergo a series of stringent and standardized performance tests before leaving the factory. These tests serve not only as the final gatekeeper for product quality, but also as a formal commitment to users regarding operational safety. I. General Performance Tests: Verificat...

In the tank farm and batch material transfer sections of chemical production, the short-cycle transportation of highly corrosive process fluids has always been a core pain point in equipment selection. The fluoroplastic self-priming pump is a corrosion-resistant conveying device developed specifical...
