Recently, Hefei Huayun Machinery Manufacturing Co., Ltd. successfully shipped a batch of explosion-proof and corrosion-resistant hose pumps of various models to China National Petroleum Corporation (CNPC). As the primary drafting unit of the hose pump industry standard (JB/T12753-2015), Huayun Machinery has leveraged over 20 years of manufacturing expertise and multiple national patents to meticulously develop a series of high-performance, highly adaptable explosion-proof and corrosion-resistant hose pumps. These pumps are designed to assist CNPC in tackling the highly challenging material transportation issues under different working conditions.

The delivered hose pumps come in a wide variety of models, carefully designed to meet CNPC’s specific needs in oil extraction, refining, and other operations. In oil extraction sites, the presence of flammable and explosive gases, along with crude oil containing significant impurities and corrosive substances, poses considerable challenges. Huayun Machinery’s explosion-proof and corrosion-resistant hose pumps are built with specially customized high-strength explosion-proof alloy materials, effectively preventing sparks caused by static electricity or friction, thus minimizing explosion risks.

Additionally, these pumps are equipped with high-performance rubber composite hoses that offer exceptional wear and corrosion resistance. This ensures effective protection against the abrasive impact of crude oil impurities and chemical erosion, significantly extending equipment lifespan while reducing maintenance costs and downtime.

In refining processes, where highly corrosive chemicals are involved, the pumps are fitted with specialized sealing systems and corrosion-resistant components. Advanced sealing materials and surface treatment technologies ensure a safe and stable conveying process, even in highly corrosive environments, eliminating leakage risks.
