1.BW series mud pump is widely used for grouting and mud jacking in engineering construction.
2.BW250 mud pump have two cylinders with different diameters and four gear shifts.Output and drilling depth are adjustable,so it can be used to grout cement slurry or equipped with 1500m drilling machine.
3.BW160/10 mud pump is widely used in railway, hydraulic engineering, metallurgical engineering, building construction, geological exploration, engineering exploration (within 1000m of the drilling depth)etc.
Henan Research Institute of Coal Science Co., Ltd established in March of 1979. At the beginning of its creation, it is a member of National Ministry of Coal Industry, mainly bears ministry and provincial scientific research projects. Over the years, it undertakes over one hundred projects authorized by original coal industry, Henan science and technology commission and coal enterprises bid inviting and it made scientific and technological achievements more than 90 items, won 45 awards, fulfilled technical consulting service over 110 items and more than 10 items of patent awards. In 1999, according to the deployment of national scientific research system reform, the original Henan Research Institute of Coal Science, listed as one of the national first batch of 242 enterprising science research institutes is delegated to Henan province with apanage management.
Keming Mechanical & Electric Department directly subordinate to Henan Research Institute of Coal Science expands from a pilot plant supported by abundant scientific research strength of Henan Research Institute of Coal Science. Now it develops into a leading enterprise in the industry of concrete spraying machine and is formed by concrete spraying machine as the main body of series of diversified products. It owes high reputation in society with high quality and technology.
