Advanced hydraulicsOptimum impeller geometry provides maxi-mum efficiency and excellent suction cha-racteristics.
New Compact DesignA compact structure allows for simpleinstallation even in confined spaces
A Unique DesignAn innovative guard (patented) pre-vents contact with rotating parts,providing protection to the end userwhilst allowing for inspection of themechanical seal.
Silent operationSpecially designed fluid ducts providevery quiet operation
Exceptional Fluid DynamicsThe fluid dynamics through the impeller andcasing are designed to minimize losses andincrease performance.
