8 Reasons to Choose a Salvatore Robuschi Centrifugal Pump

Salvatore Robuschi manufactures an Industrial Centrifugal Pump range that is ideal for handling those fluids that a standard Centrifugal Pump would struggle with. This tends to involve fluids that are particularly corrosive or have large solids in suspension. For a full list of applications, please visit the individual product pages of each pump series. Keep reading for 8 reasons to choose Robuschi for your next Centrifugal Pump.

  1. Salvatore Robuschi Centrifugal Pumps absorb energy costs:
Energy Saving GraphLost Wax Micro-Cast Impellers
During the lifespan of a Centrifugal Pump, typically 5% represents the cost of purchase, 65% represents the cost of Electrical Energy (Absorbed Power Consumption) & 30% represents the cost of Installation & Maintenance. Pumps in Alloy Steels have an approximate 10% loss in performance when compared to their Cast Iron counterparts. Through the use of micro-cast (Lost Wax) impellers, this imbalance can be corrected to provide near identical performances. This means that pumps produced in this method can represent considerable energy savings as well as reducing NPSHr values (Nett Positive Suction Head required). The graph to the right represents the energy saved on 5000 Hrs of operation of a pump with a traditionally cast impeller (top line) vs a Micro-Cast Impeller (bottom line). 10 kW more power is absorbed by traditionally cast vs micro-cast.

Lost Wax Micro-Cast Impellers Open Impeller
Vortex type impellers are commonly used in pumps to convey fluids with solids in suspension. These typically are relatively inefficient when compared to Open impellers with wear plates and generally result in high operating costs that are not always justifiable. By using open impellers with wear plates an approximate 30% reduction in absorbed energy costs can be expected, which means the up-front capital investment can be recouped in a matter of months.Vortex Impeller


  1. Vortex Type Impellers: Robuschi Centrifugal Pump
  • “Soft” Pumping
  • Reduced risk of clogging

The large free passage between the casing and the recessed impeller allows the Centrifugal Pump to pass solids up to 90% of the diameter of the discharge port. This configuration also facilitates the protection of the casing and gasket housing from abrasion and the passage of long filamentous or delicate solids without damage.

  1. The most economical range of Centrifugal Pumps for arduous applications:

The HD, HG & RS Close Coupled Centrifugal Pump ranges were developed to face the need for pumps for arduous and difficult applications whilst ensuring a reduced cost of purchase. The use of Micro-Cast components, simplicity of manufacture & the modularity of its components (Open/Closed/Vortex Impellers with various sealing options) enables them to be used in heavy-duty conditions but with lower purchase and maintenance costs.

Close Coupled Centrifugal Pump

  1. Interchangeability:

The Process & Close Coupled Centrifugal Pump ranges (HD, HG & RS) are produced according to ISO 2858/5199 dimensions norms and are therefore interchangeable with themselves and other pumps produced to this standard.

  1. Modularity:

All Salvatore Robuschi Centrifugal Pumps are built with modularity in mind in order to reduce the cost of spare parts and warehousing. Many pumps will feature common & interchangeable spare parts.

  1. Quick delivery times:

Average delivery times of 15-30 working days, including the ISO 2858/5199 Process Centrifugal Pump range.

  1. Quick & ready spares availability:

Shipment of spare parts (including seals) can be made within 24/72 hrs.
