Vertical Immersion Pump

Salvatore Robuschi Vertical Immersion Pumps

The Vertical Immersion Sump Pump range from Salvatore Robuschi is built in accordance with ISO 5199 Norms and features the same impeller choices of the Single Stage End Suction Centrifugal Pumps (Closed, Semi-Open, Recessed Vortex & Multi-Channel impeller options):

• The Closed Impeller (RDV) Range of pumps is suited to pumping clean liquids or a small percentage of suspended solids
• The Open Impeller (RGV) Range of pumps is suited to pumping liquids with non-fibrous solids, viscous liquids and fluids with entrained gases/air
• The Recessed Vortex Impeller (RCV) Range of pumps is suited to handling large, fragile, abrasive and fibrous solids (up to 90% of inlet diameter), up to 1000cPs fluids and up to 50% entrained gases/air
• The Multi-Channel Impeller (RBV) Range of pumps is best suited for viscous and solid-laden (non-fibrous) liquids or applications with low NPSHa/high-efficiency requirements

All vertical pumps are heavily customisable and include various lubrication systems, ensuring the vertical pumps are suited for almost any type of sump application.
