*highly abrasive liquids
*highly acid liquids
*highly acid liquids with abrasive suspensions Type of seal:
*rubberized sleve and bush
Low maintenance Pump-motor coupling:
*flexible coaxial joint
These pumps are basically very similar to the ones of the Jolly series, but they are not mounted on cantilaver brackets since they have at their top a strong metallic structure with one lifting eyebolt, through which a metallic rope, chain or any other suspension device keeps them in a vertical position inside tanks or wells: in this way, it is also eventually very easy to move them from one position to another.
They only have one flexible coaxial joint between the electric motor and the shaft, and they are manifactured with two standard heights of suction for installed power up to 12.5 HP, which are 1 meter (3.3') and 1.5 (5') meters; when the power is higher (up to 100 HP), the height of suction is 1.6 meters (5.3').
