Rapidex
EU only product. The Rapidex™ is a low shear agitator with specially designed marine type propeller blades that ensure a cavitation-free operation while providing extremely intense agitation.
The Rapidex is a low shear agitator with specially designed marine type propeller blades that ensure a cavitation-free operation while providing extremely intense agitation. Available in diameters from 110 – 800 millimeters the smooth shape and finish of the Rapidex impeller blade make it very suitable for your sanitary applications. The Rapidex operates at a low tip speed and consumes very little power.
The Rapidex is used across many industries including food, beverage, pharmaceutical, cosmetic, and wastewater treatment. Ideal for high viscosities up to up to 25,000 mPa*s, the Rapidex is perfect for mixing miscible liquids, dissolving of solids that are unlikely to agglomerate, as well as preventing sedimentation and heat input.
The Rapidex is engineered for trouble-free agitating year after year. All components including the shaft, ball bearing, coupling and motor are designed to withstand maximum loads while delivering stability and minimal need for service.

Low tip speed / low power consumption
The power consumption of any mixing impeller is a result of the following parameters:
1. viscosity and specific gravity of the mix.
2. diameter, rpm and power number of the impeller.
The parameters of the mix itself may be given, whereas two parameters of the impeller can be varied so as to obtain a certain impeller tip speed. The combination of the speed (rpm) and the impeller diameter results in the actual tip speed. A high tip speed requires high energy whereas a low tip speed will result in considerable energy savings. The table shows how the tip speed influences the power consumption of a Rapidex agitator.
