The predecessor of Putzmeister Solid Pump Co., Ltd. is Putzmeister Industrial Technology Department, which produces four types of hydraulic piston pumps (KOS, HSP, KOV, EKO), which are widely used in sewage treatment, mining, metallurgy, waste treatment, petrochemical industry, cement industry, dredging, thermal power plant, tunnel construction, land reclamation, paper making and many other fields. Provide a safe and reliable high-pressure long-distance pipeline transportation solution for viscous materials with high solid content and complex components. Putzmeister has a high degree of automatic control and can realize relatively accurate displacement adjustment. In the field of solid waste treatment and hazardous waste treatment projects, Putzmeister systems and products have explosion-proof performance, and great efforts have been made for their higher safety and reliability. KOS pump can be used for pipeline transportation of hazardous waste sludge slurry. SMP system (also known as hazardous waste pretreatment system, hazardous waste feeding system or slurry preparation system) can uniformly crush and mix hazardous wastes with complex components and different shapes, and pump them into incinerator or cement rotary kiln to improve incineration efficiency, prolong the life of refractory bricks and reduce flue gas emission. In the treatment project of kitchen waste and organic waste, Putzmeister not only provides special feeding and returning system for anaerobic digestion process, but also provides users with kitchen waste transfer station and pipeline distribution system for composting process.
In the field of river and lake dredging, Putzmeister system is applied to large dredging ships or dredging docks, and the silt and sediment are transported to the storage yard several kilometers away through fast connecting pipelines.
In the field of tunnel construction, Putzmeister provides slurry, soil and mortar pipeline transportation system connected with shield machine, which is especially suitable for earth pressure balance system.
In other fields, such as land reclamation (land reclamation), transportation of pulp and waste paper mud in paper industry, transportation of slaughter wastes in slaughterhouses, etc., Putzmeister's products are also widely used. Putzmeister was acquired by Sany Germany Co., Ltd. and CITIC Fund, a subsidiary of Sany Heavy Industry, on October 3, 20 12 10, with a shareholding of 100%, of which Sany's German contribution was 324 million euros. After the ups and downs, this former concrete giant ushered in the Spring Festival.
