      • VERTICAL pumps

      • Vertical centrifugal pumps with closed, open, vortex and channel impeller according to ISO 5199 norm

        Vertical immersible sump pump. The pump body is immersed into the liquid and the motor is mounted above the plate, keeping it away from the liquid. The discharge pipe is separated from the column pipe and the lubrication of the bearings is normally obtained by means of the same pumped fluid, or from an external lubricating source in abrasive services. 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.

        Use
        Vertical pumps are used in all industrial applications, refining, oil and gas production, chemical, pulp and paper and water facilities. They are also used in drainage sumps, oily water sumps and tank transfer.

        Technical Specifications

        • See curves for horizontal type RN-RD-RG-RB-RC

      • CANTILEVER pumps

      • Vertical cantilever centrifugal pumps with vortex and channel impeller.

        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.

        Use
        Cantilever pumps are used for sludges, slurries and liquids containing large or long solids. They are also used in drainage sumps, oily water sumps, tank transfer,food processing, ground water development and irrigation, heavy oil, oil sand and shale, paper stock, sewage collection and treatment, shower pumps, slurry processing and transfer.
