CANTILEVER pumps

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.

Construction Versions

Typical installation: Cantilever pump is installed at the top of sump/tank and works without level controls. With liquid level above the pump "priming holes" the pump works properly but as soon as the liquid level is below the suction port, the pump will be unprimed and work dry. The pump will restart to work when the liquid level reaches the pump "priming holes".

Typical installation with suction extension: Cantilever pump is installed at the top of sump/tank and works without level controls. With liquid level above the pump "priming holes" the pump works properly but as soon as the liquid level is below the end of suction extension or when NPSHa is lower than NPSHr, the pump will be unprimed and work dry. This arrangement allows to empty tanks up to 5 meters below the suction port. The pump will restart to work when the liquid level reaches the pump "priming holes".

External installation: Cantilever pump is installed beside of sump/tank and works without level controls. When the liquid level inside the tank is above the pump casing, the pump can operate but as soon as the liquid level is below the suction port, the pump will be unprimed and work dry. The pump will start again to work when the liquid level inside the tank is above the pump casing. The liquid level inside the tank must be lower than recirculation pipe in order to allow the liquid back into the tank and not damage motor. This arrangement allows to work with very hot fluid (up to 300°C) with suspended solids.
