A personal-care contract manufacturer based in Sydney, Australia required a sanitary rotary lobe pump to transfer shampoo, conditioner and similar products from a mixer or Pallecon IBC into a 90 L filler hopper.
The process requires controlled flow, low shear and low aeration. The pump must also handle changing product viscosity while maintaining a hygienic product-contact path and adjustable speed for transfer and cleaning cycles.
Challenges When Pumping Shampoo and Conditioner
Shampoo and conditioner are viscous, formulation- sensitive products. Excessive pump speed can create unnecessary shear and air entrainment, leading to foaming and unstable filling. At higher viscosity, an unsuitable pump may also cause increased load, inconsistent flow or reduced transfer efficiency.
The customer required a pump that could transfer personal-care products from a mixer or Pallecon IBC to a 90 L filler hopper under flooded-suction conditions. The system needed to maintain a controlled flow while allowing the operator to reduce pump speed when the formulation required gentler handling.
The main requirements were:
1.Stable transfer across a broad viscosity range
2.Low-shear handling for shampoo and conditioner
3.Low aeration to help control foaming
4.Hygienic product-contact materials
5.Adjustable flow for filling and cleaning cycles
When Transfer Control Becomes the Process Bottleneck
For personal-care production, the transfer stage directly affects filling stability and product quality. The pump must not simply move the product; it must handle viscosity changes without excessive speed, aeration or unnecessary stress on the formulation.
A fixed-speed pump may provide limited flexibility when different shampoo or conditioner formulations are processed. The required flow can change with product viscosity, temperature and filling conditions. The pump therefore needs variable-speed control and a suction arrangement that supports consistent product intake.
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.
