Viesse produces pumps with the ROBUSTA brand for both the industrial market and for land drainage.
The pump casing is separated by the volute, which now becomes a shield protecting the impeller only, while the pump casing is just the shell housing for both. Briefly, the revolutionary idea behind the ROBUSTA consists of a volute-disk inside the pump body that acts as armouring, protecting the impeller and at the same time is entirely interchangeable as additional benefit. The volute has no internal built-in screws and so it is easily replaceable when the pump is worn out.
The armouring is very hard and resistant to abrasion – its resistance to abrasion is assured by the use of specific materials – and this makes the pump ideal for continuous use, even with muddy or sandy water, etc.
The ROBUSTA hydraulic module was designed using software provided by the Department of Machinery of the University of Padua. The aim of the design was to enhance the hydraulic efficiency and obtain the maximum energy savings possible from open impeller hydraulics. The result of this research was a hydraulic system with slim vanes with a specific hydraulic profile and assuring large gaps for the flow, and with the impeller engineered to optimise efficiency and reduce the effect of wear and tear on the surface of the vanes.
The pump casing can be centrifugal, self-priming or other special forms depending on the customer’s request.
The shape of the self-priming pump is actually larger and has an innovative design than those currently available on the market, as it was studied for fast and safe priming.
