Jiangsu Haifa Machinery Manufacturing Co., Ltd.

In 2026, the release of SH/T 1860-2026 "Adiponitrile for Industrial Use" marked the first time China established a unified national product standard for adiponitrile. With the continuous advancement of domestic production projects such as Tianchen Qixiang and Shenma, adiponitrile is transitioning from a "bottleneck raw material" to scaled-up, standardized competition. Recent research indicates that butadiene hydrocyanation remains the mainstream industrial route, while emerging technologies such as process intens, heat pump distillation, AI optimization, and low-carbon electrosynthesis are focal points. Adiponitrile plants involve hydrogen cyanide, butadiene, nitriles, and high-purity intermediates, and pump equipment must prioritize low leakage, corrosion resistance, NPSH margin, API 682 sealing, and full-lifecycle reliability. Jiangsu Haifa Machinery Manufacturing Co., Ltd. (www.jslgpump.com) offers API 610 OH2, OH3,5, VS series pumps, and API 685 magnetic drive pumps, suitable for conveying adiponitrile, hexamethylenediamine, nylon 66, and high-hazard chemical media, with material, sealing, and hydraulic optimization available for high-pressure, volatile, and corrosive conditions.
