Liquid detergents are formulation-sensitive products. Their viscosity, pH and chemical composition may vary depending on the surfactant concentration, additives and final product requirements.
Surfactants can generate excessive foam when the pump introduces air or operates at an unsuitable speed. Alkaline ingredients or oxidizing components may also affect wetted parts and mechanical seals if the material selection is not matched to the formulation.
During production, the pump must therefore provide controlled transfer without creating excessive aeration, unnecessary shear or unstable flow.
The Main Challenges When Pumping Detergent Are:
Surfactants may increase foaming during transfer
Viscosity can change with formulation and temperature
Alkaline or active ingredients may affect material compatibility
Excessive speed may cause air entrainment and unstable filling
Residual detergent must be removed effectively during cleaning cycles
Material Selection for Detergent Transfer
Selecting Materials for Chemical Compatibility
Material selection should be based on the detergent formulation, concentration, pH, temperature and cleaning procedure.
For many water-based detergent applications, 316L stainless steel is commonly selected for product-contact components because of its corrosion resistance, cleanable surface and suitability for hygienic processing.
The seal material should also be matched to the operating conditions. Depending on the formulation, temperature and chemical concentration, options such as EPDM, FKM or PTFE-based sealing materials may be considered.
The final configuration should be confirmed according to the actual detergent composition and compatibility requirements.
Rotary Lobe Pump Solution
Controlled and Low-Aeration Detergent Transfer
A rotary lobe pump provides positive displacement transfer, helping maintain a stable flow even when the detergent viscosity changes.
With variable-frequency drive control, the pump speed can be adjusted for mixing, transfer, storage and filling operations. Low-speed operation helps reduce excessive foaming and protects the stability of the product during transfer.
The pump can also be configured with:
316L stainless steel product-contact parts
Chemical-compatible mechanical seals
VFD speed controlSanitary clamp connections
CIP-compatible product-contact paths
Optional flushing or cooling arrangements for the seal
Reversible flow for flexible transfer operation

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.
