The pump body is immersed into the liquid and the motor is mounted above the mounting plate out of the corrosive area. Oversize heavy duty ball bearings are supplied with grease fittings and located above the mounting plate out of the corrosive area. This means no bearing in the liquid, no seal or bearing bush and bearing assembly is sealed-off to prevent bearing’s contamination by liquids or gases-vapors. This allows the pump to run dry without risk of damage and so reliable operation and reduced costs. The possibility to customize mounting plate shape and dimensions, discharge flange position and column lenght, allows designers and end-users to match sump or tank plates or flanges. Suction strainer and suction extension on request with the possibility to fit a PTFE lip seal for vapor proof construction.
