Vertical column pump series SR

Name: Vertical column pump series SR
Brand: Salvatore Robuschi
SKU: RNV, RDV, RGV, REV, RBV, RCV
Availability: InStock

In the vertical sump pump, the pump casing is immersed in the liquid while the motor is mounted above the baseplate, away from the medium. The vertical design is in accordance with ISO 5199 and is available across the entire SR hydraulic range, so the most suitable impeller can always be selected for the liquid being pumped. The baseplate (rectangular, circular or to customer specification), the discharge position and the column length can be customised, allowing the pump to be easily matched to the installation. A suction strainer and suction extension are available on request.

Impeller types & Versions

Closed impeller — for clean liquids, low NPSH values
Open impeller — for liquids containing non-abrasive solids or gas, adjustable wear plate
