Durrex lobe pumps promote the high-quality development of paper industry

China International Paper Technology Exhibition and Conference, held in the Shanghai World Expo Exhibition and Convention Center on August 14-16, 2023, has become an annual event in the industry.

Durrex pumps attended at this exhibition, with industry-leading products and technical solutions, to promote the high-quality development of paper industry.

Paper starch conveying Rotor Pumps

Starch has the characteristics of high temperature and high viscosity during the cooking and sizing process, so it has high requirement for the conveying equipment. Durrex rotor pumps, with unique structural principle, can be selected and configured based on different material characteristics and working conditions. During the material transportation process, it has the characteristics of stable operation, low noise, low failure rate, long sealing life, and easy maintenance, greatly reducing equipment usage costs and improving production efficiency for users, thus gaining recognition and selection from most of users.

Rotary pumps for paper coating transportation

Paper coating contains various chemical raw materials, and due to different characteristics of each chemical raw material, the requirements for conveying pumps also vary. Durrex rotary pumps adopt mechanical seal special for coating use developed itself, and overcurrent components of the pump are made of special materials, which make the pump have good wear resistance, stable operation, low energy consumption, easy disassembly, fewer vulnerable parts, and long mechanical seal life during use.

Rotary pumps for paper chemical transferring

The various chemical agents and additives used in the papermaking process, such as rosin, dry strength agent, wet strength agent, sizing agent, defoamer, etc., have high metrological requirements for the addition of chemicals. Moreover, the PH and viscosity of each chemical are different, and the complexity of the working conditions is also different, which requires high pump performance. Durrex Lobe Pumps are based on application technology and configured differently according to material characteristics and operating conditions to ensure smooth, safe, and efficient material transferring.

Rotary pumps for conveying paper waste water and sludge

The treatment of paper-making wastewater contains various hard impurities such as sand particles and pulp fibers, which cause wear and tear on the pump. Conventional pumps require a large number of vulnerable parts to be replaced every year, and maintenance is cumbersome, labor-intensive, and costly. Durrex rubber rotor pumps are designed based on the characteristics and operating conditions of sewage sludge. The rotor is fully or partially wrapped with wear-resistant rubber, and pump chamber is lined to increase the wear resistance of the flow passage components and reduce the maintenance cost of vulnerable parts. The modular design makes replacement simple and maintenance convenient, reducing equipment usage and maintenance costs for users.

Durrex pumps has mastered the core key technologies of research and development, manufacturing, and application of industrial pumps such as Rotary Lobe Pumps, homogeneous emulsion pumps, rubber rotor pumps, refine grinding pumps, and leak free chemical magnetic pumps. With over 20 years of experience in industrial pump research and development, exquisite manufacturing technology, high standard quality management, rigorous product testing, and professional technical solutions, Durrex pumps has received attention and praise of customers at home and abroad.
