Edible oil air-cooled pumps use air convection cooling without cooling water, avoiding oil-water contamination. They feature low failure and maintenance costs, suitable for high-temp oil conveying in refining, pressing and frying lines.

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, Teffiko 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.

TEFFIKO 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.
