Paper surface sizing agent conveying pump

Paper surface sizing agent conveying pumpIt is a positive displacement rotary pump designed specifically for the paper industry, using a dual rotor synchronous reverse rotation structure to achieve periodic changes in the sealed chamber through the geometric fit between the rotor and the pump body. This pump is optimized for the high viscosity and strong metering requirements in the surface sizing process of papermaking. It can handle a wide range of medium viscosities and is suitable for the entire process from adding sizing agents to coating technology.

working principle

By synchronously driving two cam rotors to rotate in reverse, a sealed chamber is formed between the rotors and the pump body. During the rotation process, the chamber volume undergoes periodic changes: the volume on the inlet side expands to create a vacuum, which sucks in the adhesive slurry; The rotor continues to rotate, and the slurry is wrapped in the sealed chamber and pushed towards the outlet side; The volume on the export side is reduced, and the slurry is discharged under pressure. The non-contact design between rotors reduces friction, and synchronous gears ensure smooth operation, achieving continuous and stable medium transport.

Paper surface sizing agent conveying pumpApplication advantages

Efficient and stable: The flow rate is strictly linearly related to the speed, which meets the strict requirements of papermaking process for the accuracy of sizing agent ratio.

Strong adaptability: It can handle a full range of media from low viscosity water agents to high solid content pulp, covering the needs of multiple papermaking conditions.

Energy saving and consumption reducing: The volumetric design reduces energy loss, is more energy-efficient than centrifugal pumps, and has lower long-term operating costs.

Environmental safety: The sealed conveying system prevents leaks and meets the dual needs of clean production and employee safety in the paper industry.

Flexible customization: The rotor material and sealing form can be selected according to the characteristics of the medium, supporting various connection methods such as flanges, screws, clamps, etc.
