Technical Information

From manual craftsmanship to intelligent manufacturing,China’s paper industry has evolved over millennia.As the core"fluid heart,"the rotor pump ensures quality via precision delivery of pulp and chemicals,guarantees continuous production with rugged reliability,and drives green,low-carbon transformation through smart capabilities—propelling automation,quality enhancement,and digitalization in papermaking,thus fueling high-quality advancement in traditional manufacturing.

Despite costing several times more than centrifugal pumps, rotary lobe pumps maintain strong market demand due to their core advantages: Performance-wise, they integrate strong self-priming, high head performance, low shear force, and extensive media adaptability (e.g., gas-liquid mixtures/slurries/high-viscosity fluids); Economically, wear parts require replacement only every 2-3 years or longer, with maintenance costs constituting only 15% of total pump price, while replacements can be completed by a single operator in 30 minutes; Spatially, they occupy merely 1/2 to 1/3 the footprint of screw pumps. Bonve empowers industrial fluid transfer through customized solutions.

Bonve cam rotor pumps are robust and easy to maintain, widely used in fine chemicals, food, papermaking, and daily chemical industries. They are suitable for conveying materials such as polyurethane, resin, sauces, syrup, ice cream, toothpaste, shower gel, shampoo, feces, and dirty oil. Bonve provides customized solutions. If you have other pump needs, please feel free to contact us. However, we don't just make these pumps.

Definition, working principle (three-stage volume change) and six core features (adaptability to viscosity ranging from 10cp to 2.5 million cp, temperature range of -30~200℃, etc.) of Bonve high-viscosity rotor pumps, as well as the brand's service philosophy, are as follows: A high-viscosity rotor pump (also known as a cam rotor pump) is a positive displacement pump. Its core feature is that through the periodic meshing and separation of rotors in the closed pump cavity, the working volume changes regularly, thereby realizing the suction, displacement and discharge of fluids.

comprehensively analyzes seven core fault modules in rotor pumps including starting difficulty,suction failure,and abnormal vibration,providing targeted maintenance solutions.It covers key technical operations such as pump cleaning,rotor replacement,and seal repair,with access to Bonve Pumps'professional after-sales service channels to ensure optimal equipment performance.

Selecting a rotary pump requires systematic analysis of fluid properties (media state, viscosity, corrosiveness), process parameters (peak flow, system pressure), operational conditions (installation constraints, running modes), and special scenario needs (sanitary standards, solid-containing media). A four-step methodology—preliminary type screening, parameter calibration, in-depth verification, and scenario optimization—ensures technical alignment while mitigating dry-run and particle sensitivity risks, guaranteeing efficient and stable operation.
