SINUSOIDAL PUMPS
Sinusoidal pumps are engineered for ultra-gentle transfer of viscous and shear-sensitive fluids, making them ideal for food, dairy, beverage, cosmetic, and pharmaceutical applications. Their smooth, sinusoidal rotor delivers powerful suction and pulse-free flow, enabling efficient unloading of even the most challenging products. Designed with a single shaft and single seal, they are simple to maintain and can be both CIP cleaned or fully strip cleaned. Sinusoidal pumps also offer exceptional energy efficiency using up to 90% less energy than rotary lobe pumps on high-viscosity duties. Alliance Fluid Handling holds UK stock of complete pumps and spares for rapid supply and support.
