Robuschi’s Vertical Cantilever Sump Pump is designed with a non-clogging vortex and a channel impeller.
Salvatore Robuschi’s Canitlever Sump Pump is perfect for a range of applications due to its dry run capabilities. Another benefit of the Cantilever Pump is its low maintenance costs.

Vertical Cantilever Sump Pumps are typically used for sludges, slurries and liquids containing large or long solids. The pumps are also used in:
The pump body is immersed into the liquid and the motor is mounted above the plate, keeping it away from the liquid.
Oversized heavy-duty ball bearings are supplied with grease fittings and located above the mounting plate out of the corrosive area. This means:
The possibility to customise the shape and dimensions of the mounting plate as well as the discharge flange position and column length allows designers and end-users to easily match sump or tank plates/flanges.
Channel Impeller: For slightly cotaminated liquids or non abrasive slurries. The impeller is designed with special blade geometry for low NPSH and high free passage. These impellers are highly efficient
Vortex Impeller: For chemical and crystalline suspensions, all viscous liquid, liquid with high concentrations of fibrous suspensions, municipal and industrial waste water, and every kind of sludge. This impeller has a free passage of up to 150 mm.
The Cantilever Sump Pump is installed at the top of the sump/tank and works without level controls. With the liquid level situated above the pump ‘priming holes’, the pump works properly. As soon as the liquid level is below the suction port, the pump will be unprimed and work dry. The pump will restart when the liquid level reaches the pump-priming holes.
The Cantilever Pump is installed at the top of the sump/tank and works without level controls. With liquid level above the pump priming holes, the pump works properly. As soon as the liquid level is below the end of the suction extension or when the NSPHa is lower than the NSPHr, the pump will be unprimed and work dry. This arrangement allows the emptying of tanks of up to 5 meters below the suction port. The pump will restart when the liquid level reaches the pump-priming holes.
The Cantilever Pump is installed beside the sump/tank and works without level controls. When the liquid level inside the tank is above the pump casing, the pump can operate. As soon as the liquid level is below the suction port, the pump will be unprimed and work dry. The pump will begin to work again once the liquid level inside the tank is above the pump casing. The liquid level inside the tnk has to be lower than the recirculation pipe in order to allow the liquid back into the tank without damaging the motor. This arrangement allows the usage of very hot fluid (up to 300C) with suspended solids.
Pump length: up to 1.8m, but can be extended by means of suction extension which allows the pump to operate with a liquid level under the impeller level.
Mounting plate: rectangular, circular, or according to customer’s specifications
PTFE Lip Seal for vapour proof construction
Materials: Cast Iron GJL250 or AISI 316. Can also supply CA6NM (400HB hardness), AISI 304, AISI 904, duplex, and super duplex, upon request.
Suction strainer and suction extension available upon request
