The Centrifugal Process Pump is manufactured with interchangeable parts and wide sealing system choices. The customisable design features allows these Centrifugal Pumps to be easily employed in applications with aggressive chemicals, suspended solids, high temperatures, high viscosities and high specific gravities.
Robuschi’s range includes the RD, RG, RB and RC series’. The RD and RG series’ are manufactured from Stainless STEEL 316 as standard, although others are available. The RB and RC series’ are usually manufactured from Cast Iron or Stainless Steel and are commonly used for Wastewater applications where chemical resistance is not needed.
The main aspects of this series are the modularity of design, interchangeability of parts, wide sealing system choices but also hydraulic design interchangeability (ability to mount both Open and Closed Impellers on the same pump casing) and the ability to pump under low NPSHa conditions. These features allow the Centrifugal Pump to be easily employed in applications with aggressive chemicals, suspended solids, high temperatures, high viscosities and high specific gravities.
The RC Series of Single Stage End Suction Centrifugal Pump feature a Vortex Impeller which is recessed into the back of the pump casing. This means they are ideally suited for soft pumping applications or with high solids content (up to 180mm ø free passage) as most of the fluid passes through the Centrifugal Pump without any direct contact with the impeller. This ensures that crystals, delicate solids (such as peas, corn, beans, olives, seeds, granules), flakes of biological mud, leather parts etc… can be conveyed without damage and do not come into contact with the mechanical seal.
Furthermore, long filamentous solids can pass through the Centrifugal Pump without any damage. The Vortex Impeller is also able to pump entrained gases up to 50% in concentration with the fluid. For this reason, these pumps can be used in applications where the fluid has difficulties in getting to the suction port and are a great solution for the transfer of viscous fluids up to 1000 cPs.
RC CENTRIFUGAL PUMP RANGE: Free passage of large solids: The recessed impeller ensures the passage of the solids and filamentous materials equal to 90% of the delivery port. Long and filamentous solids pass through the pump without clogging or causing damage.
Resistance to wear: Higher abrasion resistance is achieved as the pump casing has been designed to pump liquids together with suspended solids even if abrasive. Surface continuity avoids the presence of clogging and all wearing points have been properly shaped.
One casing cover fits 14 different sealing systems: Only 1 Casing Cover is used for every size of the pump and it can fit every seal type, brand and seal arrangement! The Seal Chamber, which is cylindrical, has dimensions bigger than those suggested by ISO 5199 Norms to grant the best circulation of fluid. Different seal types can be used using limited components, so it is always possible to change from one execution to another. For example from a Single Mechanical Seal to a Double, Packed Gland or Cartridge, by just replacing a few components. As a result, it is easy to modify the pump for a new plant or process requirement in a fast and cost-effective manner. Furthermore, this modular system allows limited stockholding of spares to cover the whole pump range.
