Cantilever

Vortex And Channel Impeller

Vertical cantilever sump pumps with non-clogging vortex and channel impeller.

The pump body is immersed into the liquid,whilst the motor is mounted above the plate, keeping it away from the liquid.

Oversize heavy duty ball bearing are supplied with grease fittings and located above the mounting plate out of the corrosive area. This means:

  • None of the bearings are in the liquid and there is no shaft seal or bearing bush;
  • Bearing assembly is sealed-off to prevent bearing contamination by liquids or gases-vapors;
  • Pumps can run dry without risk of damage;
  • Reliable operation and reduced cost.

The possibility to customize mounting plate shape and dimensions, discharge flange position and column length, allows designers and end-users to match sump or tank plates or flanges.

 

FIELDS OF APPLICATION:

Used for sludges, slurries and liquids containing large or long solids.

Typical applications include: drainage sumps, oily water sumps, tank transfer, food processing, ground water development and irrigation, heavy oil, oil sands and shale, paper stock, sewage collection and treatment, shower pumps, slurry processing, slurry transfer.

Fast facts

 

Pump length: up to 1,8 meters.
Can be extended by means of a suction extension allowing 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 vapor proof construction.

 

Materials: Cast Iron GJL250 or AISI 316.

 

Bearing bush materials: bronze, rubber, RULON and PEEK
Upon request CA6NM (400HB hardness), AISI 304, AISI 904, duplex, superduplex, CA6NM (400HB hardness)

 

Suction strainer and suction extension on request.

Impeller type

Impeller RB

Channel Impeller

Slightly contaminated liquids or non abrasive slurries. Special blade geometry for low NPSH and high free passage. High efficiency and low NPSH.

Impeller RC

Vortex Impeller

Chemical and crystalline suspensions, all viscous liquids, liquids with high concentrations of fibrous suspensions, municipal and industrial wastewater, every kind of sludge. Free passage up to 180 mm.

Installation

Typical installation

The 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.

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”.

VASCA 1

Typical installation with sution extension

The 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.

As soon as the liquid level is below the end of suction extension or when the NPSHa is lower then 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”.

VASCA 2

External installation

The 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.

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 has to be lower than recirculation pipe in order to allow the liquid back to into the tank and not damage motor.

This arrangement allows to work with very hot fluid (up to 300°C) with suspended solids.
