Most simple blending applications require a controlled uniform flow pattern. This ensures that the whole of the tank contents is kept in motion and that the tanks are not left unmixed. The best way to achieve this turn over is to use an axial flow impeller which discharges downward towards the vessel bottom. 

A pitched blade turbine impeller has traditionally been used for blending and solids suspension, however the discharge flow can be spread by more than 45. This leaves a low velocity area under the shaft where agitation is difficult or solid can settle. The Chemplant RTF4 creates an axial flow pattern with a very even velocity profile across the impeller. This minimizes any low velocity areas an ensures the tank contents are quickly and thoroughly mixed. At the same time the RTF4 has the lowest power consumption for a given discharge velocity, which can give energy savings of up to 60%. 

The greatest benefit of the RTF4 is the low torque requirement for a given amount of flow. Low torque means that the drive and shaft sizes can be minimized and the service factor on the drive maximized. This results in extended agitator life and normal operational spares requirements will be reduced. The RTF4 has one of the lowest torque requirements of any impeller which equates to significant capital and running cost savings.

Industrial Automatic self-cleaning Water Filters

Real-time self-cleaning filters: clean themselves automatically when head-loss across the screen reaches a pre-set value. 

Uninterrupted water supply: the filter cleans itself in just seconds without interrupting downstream flow.

Modular structure: different diameters, suitable for use singly or in manifold configuration, providing optimal solutions to meet specific customer requirements. 

Flexibility of control options: Hydraulically or electronically controlled units. 
Flushing according to pressure differential and/or time. Continuous flushing, alarm signals, flushing counter etc. 

Wide range of filtration degrees: from 3500 to 3 micron.
