Where Human-Grade Hygiene Meets Uncompromising Precision.
The pet wellness industry is evolving at lightning speed. Today’s pet parents treat pets as family, driving unprecedented demand for transparency, safety, and nutritional efficacy. In this competitive landscape, market leaders like PetIQ and tier-one pet supplement manufacturers have officially upgraded their production facilities to Human-Grade and Pharmaceutical-Grade standards.
Meeting this gold standard requires more than conventional fluid equipment. It demands a transfer system engineered without compromise.
Bonve Sanitary Rotary Lobe Pumps redefine how premium pet paste is handled
Nutri-Vit Plus and dense functional pastes are not ordinary liquids. They are complex, high-calorie, multi-component emulsions loaded with malt extract, omega oils, taurine, active enzymes, and heat-sensitive vitamins. Transferring these dense, sticky formulations from mixing vessels to high-speed tube and sachet filling lines presents four critical process bottlenecks:
Nutrient Shear & Emulsion Separation: High mechanical shear or localized heat from improper pumps fractures delicate emulsion matrices—causing irreversible oil separation, texture degradation, and nutrient breakdown.
Extreme Viscosity & Suction Loss: Paste formulations with apparent viscosity reaching hundreds of thousands of centipoise create heavy friction, risk cavitation, and starve downstream filling lines.
Micro-Aeration & Dosing Inaccuracy: Air entrainment or flow pulsation inside the pump chamber creates internal bubbles, resulting in inconsistent fill weights, splashing, and defective packaging seals.
Hygiene & Cross-Contamination Risks: Residues lingering in dead legs or non-hygienic seals jeopardize microbial safety and trigger expensive batch rejections.
Typical Pet Food & Supplement Applications
Pet Nutritional & Vitamin Pastes: High-calorie daily supplements, malt hairball gels, energy pastes (e.g., Nutri-Vit Plus).
Functional Gels & Therapeutics: Joint health pastes (glucosamine/chondroitin), calming gels, oral probiotics, and veterinary deworming pastes.
Wet Pet Food Gravy & Emulsions: High-meat slurries, pureed treat pouches, broth dosing, and functional liquid treats.
Filling Line Feeding: Continuous buffer transfer to automatic tube filling/crimping machines, sachet packers, and syringe-type dispensers.
Engineering Highlights
1. Low Shear. Zero Compromise on Bioactivity.
Active vitamins (A, D, E, B-Complex), taurine, and fatty acids are vulnerable to shear and heat. Bonve 4th-generation synchronized lobe rotors rotate with micro-clearances, creating continuous displacement cavities that gently cradle and move dense pastes. No squeezing. No crushing. No friction-induced heat. Every batch retains its intended texture, natural palatability, and full biological value.
2. Mastery Over Extreme Viscosities.
Engineered to handle materials with viscosities up to 1,500,000 cP. Whether pumping cold malt-based nutritional gels, pre-mix pastes, or thick recovery supplements, Bonve delivers massive suction capability (-0.095 MPa vacuum) and steady discharge pressure up to 1.2 MPa without clogging or slipping.
3. Laminar, Bubble-Free Filling Line Synchronization.
Equipped with variable frequency drive (VFD) speed control, Bonve rotary lobe pumps deliver smooth, pulsation-free laminar flow directly to multi-nozzle tube, jar, or pouch filling lines. Continuous cavity delivery eliminates air bubbles and pressure surges, ensuring pinpoint volumetric dosing accuracy across every packaging cycle.
4. Certified Human-Grade Hygienic Design.
Crafted from electropolished AISI 316L stainless steel (surface roughness Ra < 0.8 µm) with zero internal dead zones. Certified with FDA, CE, and ISO standards, Bonve pumps support seamless CIP (Clean-in-Place) and SIP (Steam-in-Place) cycles, ensuring full traceability, rapid flavor changeovers, and audit-ready compliance.
Working Principle
Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.

FAQ
1. How does Bonve prevent oil separation and nutrient degradation in vitamin pastes?
A: Bonve rotary lobe pumps utilize precision-machined bi-wing or tri-lobe rotors running at low RPM. By maintaining large internal displacement cavities and zero metal-to-metal contact, product is conveyed in gentle, continuous fluid packets without high shear or localized friction heating. This completely preserves fragile emulsion bonds and heat-sensitive vitamins.
A: Yes. High-speed tube and pouch packaging requires stable, continuous feeding. Bonve positive displacement design produces a smooth, pulse-free discharge stream. When synchronized with your PLC and filling hopper level sensors, it maintains constant pressure, preventing air bubble entrainment and eliminating dosing weight deviations.
