ABOUT US
Tianjin Promising Machinery Manufacture Co., Ltd.
Tianjin Promising Machinery Manufacturing Co., Ltd. (hereinafter referred to as "Promising") is located in the Beichen Science and Technology Park in Tianjin. It is a national high-tech enterprise specializing in the research, development, and manufacturing of centrifugal separation and precision transmission equipment.
For over two decades since its establishment, Promising has consistently driven by technological innovation, focusing on the R&D and production of core products such as horizontal scroll discharge sedimentation centrifuges, vertical scroll discharge sedimentation centrifuges, differentials, centrifugal drying systems, reducers, and increasers. The company's products are widely used in the chemical industry, with customers spanning more than twenty provinces across China. It is a specialized leading enterprise in the field of domestic centrifugal separation equipment.
Technical Strength and Innovative Achievements:
Independent R&D Capability: Persistent independent R&D has enabled the company to develop a series of products, with multiple models filling domestic gaps and achieving performance comparable to international advanced levels.
Intellectual Property: The company holds 2 national invention patents and 47 utility model patents.
Honors and Recognition: In 2015, it won third place in the Tianjin Innovation and Entrepreneurship Competition (Yunchuang Space Cup). In 2019, it was awarded the title of "Excellent Supplier in the Petrochemical Industry" by the China Association of Plant Engineering.
Core Products and Major Breakthroughs:
Horizontal Scroll Discharge Sedimentation Centrifuge: To meet diverse demands, the company has successfully developed and manufactured 20 models ranging from LW230 to LW1100. Among them, the LW1100 and LW650 models were certified as high-quality domestic products by the Tianjin Science and Technology Commission in 2009.
The LWMF740X2220-D fully enclosed centrifuge was submitted by a large central enterprise in Jiangsu as a major localization project under Sinopec headquarters.
The company undertakes maintenance, overhaul, and modification services for various imported centrifuges, especially large-scale ones. Post-modification, equipment stability has significantly improved, achieving vibration reduction and production increase.
Vertical Scroll Discharge Sedimentation Centrifuge: The company manufactured core components, including the rotor and differential, for the 500 series vertical centrifuges for a large central enterprise in Beijing. To separate special materials such as polyoxymethylene, it is currently developing new vertical centrifuge models like the LLFM760X2170-N.
Differential Gears, Reducers, and Increasers:
We have supplied over 30 types of differential gears for centrifuges and more than 10 types of reducers/increasers for polymerization reactors to the national chemical and soybean protein industries. Additionally, we provide manufacturing, maintenance, overhaul, and spare parts services, earning strong trust from our customers.
Centrifugal Drying System (Major Breakthrough in Localization):
A centrifugal dryer capable of processing 12 tons of resin pellets per hour has been operating stably for many years.
In 2024, a large centrifugal dryer with a capacity of 50 tons of resin pellets per hour was successfully delivered. This project was a major localization initiative under Sinopec Headquarters. In 2025, we secured orders for three additional units, which will also be exported to the Middle East region, breaking the long-term reliance on imports from the United States in this field in China.
Promising has now become a supporting supplier for domestic manufacturers of large extrusion granulation units, demonstrating the company's high-end technology and manufacturing capabilities in the localization of large centrifugal dryers.
Looking Ahead:
Promising will continue to stay attuned to market dynamics, actively address competitive challenges, and persistently pursue technological advancement and self-improvement. We are committed to providing customers with higher-quality products and services, striving to give back to society with outstanding achievements.
