the most important slurry pump manufacturer in China

Excellence Pump Industry Co., Ltd. is devoting to offering the best slurry pump solution around the world. With years of accumulation and development, we have formed a complete system of slurry pump production, design, selection, application and maintenance. Our products are widely used in mining, metallurgy, coal washing, power plant, sewage water treatment, dredging, and chemical and petroleum industries. Thanks to the trust and recognition of our clients from over 60 countries, we are becoming one of the most important slurry pump manufacturer in China.

With solid strength, Excellence has trained and attracted a large number of highly-qualified technology and management personnel. We are becoming one of the leading pioneers of the development and application of slurry pums by adopting modern design systems including CAD computer-aided design system, CAPP Computer aided process planning software, CFD hydraulic design software, simulation analysis system software, the finite element analysis software and 3D design software. Aimed at providing products of high efficiency, long life and low power consumption, we have our own complete system including the product hydraulic design, structural design, computer 3D modeling, 3D simulation of fluid test calculation and computer simulation of the whole process of running tests. Therefore, Excellence has turned a new page of the development of Chinese slurry pump industry.

Innovation is the eternal pursuit of Excellence. In addition to the traditional high chromium and manganese alloys, we also dedicate to the continuous optimization of materials for slurry pump wear parts. Cooperated with Key Laboratory of Ceramics of Tsinghua University, Kunming University of Technology, Beijing University of Chemical Technology and other Research institutions, Excellece has reached the international advanced level with the years of efforts in the development of wear-resistant ceramics, polymer composites and other non-metallic wear resistant materials. As for the hydraulic design, we are the first slurry pump manufacturer to work with Institute of Hydraulic Machinery of Tsinghua University, hoping to develop a new generation of High pressure slurry pump with high efficiency, long life and low consumption.

Excellence is with advanced design concepts as the vanguard, with excellent product quality as the foundation, with rich experience in production as powerful backing, and with meeting the market demand as the goal. Excellence Pump Industry Co., Ltd. focuses on the clients’ requirements and guarantees the complete sales service system and continuous development and innovation. Excellence is progressing and improving with “National Revival” as its responsibility, with ”Contribute to Society” as its glory, with “Benefit the World” as its lofty idea. Hope you would like to join us in our persistent innovation and create a bright future together.

15th Brazilian Mining Congress International Mining Exhibition

As the largest Latin American mining trade fair, there are over 50,000 visitors and 500 exhibitors in the International Mining Exhibition (EXPOSIBRAM) 2013. It is held every two years with hundreds of entrepreneurs, government and private organizations. In 2013, the events’ 15th edition organized by the Brazilian Mining Association will be held from September 23rd to 26th, in Belo Horizonte (MG), Brazil.

Brazil is the fifth largest country in the world, and third largest in the Americas. Brazil contains extremely rich mineral reserves that are only partly exploited, including iron ore, tin, copper, pyrochlore (from which ferroniobium is derived), and bauxite. Excellence has undertaken many projects in Brazil as well as many other places. Our booth numbers in EXPOSIBRAM 2013 are B12, B14, C11, C13. See you in Brazil!

Booth No.: B12, B14, C11, C13
Date: September 23-26
Location:  Belo Horizonte (MG), Brazil

Microbiologically Induced Corrosion

Living organisms can promote corrosion in many different environments.A variety of biological organisms thrive in both aerobic and anaerobic environments. Corrosion attributable to microbiological activity occurs most frequently
in stagnant water, which remains in a centrifugal pump when it is shut down for an extended length of time.

length of time.


Several more serious types of microbiologically induced corrosion afflict stainless steels.A certain class of metal ion concentrating/oxidizing microbes appears to concentrate ferric and manganic chlorides, both of which are potent pitting agents. These bacteria form colonies preferentially at welds in austenitic stainless steels and are capable of causing severe pitting corrosion in a relatively short time. This problem has been encountered in a variety of equipment in both salt and fresh water. It is often discovered only when the
welds begin leaking. slurry Pumps employing welded stainless steel fabrications can be afflicted by this problem if permitted to sit idle with stagnant water, either fresh or salt, for an extended period. Biocides can be used to mitigate this problem in some instances.


Finally, the decay of biological organisms can generate hydrogen sulfide, which
adversely affects the protective oxide film on copper base alloys. The enhanced biological activity in warmer tropical waters, especially under stagnant conditions, can impair the corrosion resistance of bronzes and reduce the threshold velocity at which accelerated corrosion will occur. Bronzes should be used with caution in applications where macrobiological activity is anticipated and the possibility of extended shutdowns is possible.
