The main raw materials of regenerated cellulose fiber are liquid alkali and pulp, and the crushed pulp is impregnated with liquid alkali to form a porridge-like medium. The Rotary Lobe Pump is mainly used to transfer the slurry gruel in the impregnation barrel and supply the material to the press. This condition requires small pulse, low leakage and corrosion resistance.

Alkali cellulose yellowing after the main material transfer, mixing, filtration for glue, after the dissolution of grinding for quick release for glue, recycling and other transport conditions.Bonve Rotary Lobe Pump adopts the spiral streamline junction, structure, more easy to smooth transport of high-viscosity materials, the pulse is very low. The rotor is made of stainless steel 304, with delicate design and precise processing. Rotor and rotor, rotor and pump cavity clearance is very small, high conveying efficiency, more energy-saving than screw pumps, gear pumps, low operating speed, long service life, low maintenance costs.

The homogeneous mixing pump produced by our company is called dynamic mixer in viscose fiber industry. Mainly used in viscose fiber color silk production process, used to replace the traditional static mixer, the viscose liquid, color slurry, etc. into the homogeneous mixing pump pump cavity according to a certain ratio. And then through the multi-stage rotor stator for mixing, dispersion, homogenization, relative to the traditional static mixer to improve the mixing efficiency.

Manual adjustable gap grinder pumps are divided into coarse grinding and fine grinding according to the use of working conditions and process requirements, can be used for external handwheel toothed disk gap adjustment. Toothed disk form and gap can be designed according to the feed particle size and refinement requirements, so as to meet the needs of the process. Each layer of rotor stator can be replaced independently, easy access, low maintenance costs.Bonve research pump adopts water-cooled double-face mechanical seal design, reliable sealing, long life, clean and environmental protection.

Automatic Adjustable Gap Grinding Pump is a double-disc type grinding equipment, which is composed of grinding host and servo adjusting mechanism. The adjustment of the working gap of the grinding discs is controlled by DCS system, which is adapted to the automatic cycle grinding and dissolving process of viscose, with superior performance, easy operation and low energy consumption, so as to achieve the purpose of high quality, stability and high yield. The form and gap of the toothed disk can be designed according to the feed particle size and refinement requirements, so as to meet the process requirements.
