Case Description

A large paper manufacturer has long specialized in the production of high-grade cultural paper, which is supplied to many printing companies for the printing of books and magazines. With the market's increasing demand for paper quality, especially the stringent standards for paper evenness, strength and surface smoothness, the company encountered a bottleneck in the production process. Before the introduction of Rotary Lobe Pump, conventional centrifugal pumps were used to convey paper raw materials such as pulp, fillers and auxiliaries. Pulp contains a large number of fibers, the impeller of centrifugal pumps in the conveying process is prone to excessive cutting of fibers, destroying the length and form of fibers, resulting in a decline in the strength of paper. At the same time, centrifugal pumps are difficult to accurately control the conveying volume of different raw materials, making the uniformity and surface smoothness of the paper is not stable, affecting the printing effect.

Solution

To improve paper quality, Bonve introduced eight Rotary Lobe Pump for pulp. These Rotary Lobe Pump are specially designed to gently transport the pulp, retaining maximum fiber integrity and improving paper strength. Their precise flow control ensures that the pulp, filler and additives are delivered in exact proportions, resulting in significant improvements in paper evenness and surface smoothness.

The equipment supplier provides full technical support, from installation and commissioning to regular maintenance and operator training. After using the Rotary Lobe Pump, the quality of the high-grade cultural paper has been greatly improved, and performs well in printing, which meets the needs of the high-end printing market and strengthens the company's competitiveness in the field of cultural paper.
