Viesse produces pumps with the ROBUSTA brand for both the industrial market and for land drainage.
The volute on these pumps is separate to the pump body. In this way, the volute acts as a shield protecting the impeller whilst the body acts as a casing housing it. In brief, the revolutionary idea behind the ROBUSTA consists of a volute-disk inside the pump body that acts as armouring, protecting the impeller and which has the benefit of being entirely interchangeable at the same time. The disk has no internal screws and so it is easily replaced in case of heavy machine wear.
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 perfect the hydraulic efficiency and obtain 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 on the surface of the vanes.
The pump body can be centrifugal, self-priming or other special forms to suit the needs of the customer. The shape of the self-priming pump is larger than others on the market and has an innovative design, studied to safeguard fast and sure priming.
