Bonve Lobe pumps are widely used for cosmetics and personal cares to transfer of products such as serums, creams, lotions, shampoo, toothpaste,particle-based products. Bonve positive displacement pumps are ideal for handling delicate and viscous materials, and they offer a gentle pumping action that minimizes shear stress on the product.
Bonve Lobe pumps consist of two rotating lobes that create a vacuum, which draws the liquid through the pump and into the discharge port. The lobe pumps are designed to maintain a constant flow rate regardless of the pressure or viscosity of the product being pumped.
Some benefits of using Bonve lobe pumps will include:
- Gentle handling: The gentle pumping action of lobe pumps ensures that even delicate and sensitive products are handled with care.
- High efficiency: Lobe pumps are incredibly efficient, with a high volume flow rate and low power consumption.
- High accuracy and precision: Lobe pumps are designed to deliver exact flow rates, which is critical for cosmetic products that need precise dosing.
- Easy maintenance: Lobe pumps require minimal maintenance, and they have fewer parts, making them easy to disassemble and clean.
Bonve Lobe pumps are an excellent choice for cosmetic applications due to their ability to handle delicate and viscous materials, maintain a constant flow rate, and offer easy maintenance.
Typical Applications
- Transferring emulsions (moisturizers, foundations) between mixing tanks and filling lines
- Dosing serums, essences, or oils into small-pack containers
- Handling particle-based products (facial scrubs, body polishes)
- Recirculating creams to maintain temperature and consistency during production
- Transferring high-viscosity waxes for lip balms or solid perfumes
- Built to meet the cosmetics industry’s strict standards for hygiene, performance, and product protection, BONVE lobe pump is the reliable choice for brands prioritizing quality, efficiency, and 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.
