Construction features of three-lobe RVTP pumps.
They are designed to be activated ideally by flexible coupling, although they can be activated by belts and pulleys, taking the necessary precautions to not overload the driveshaft.
The shaft opening is secured by seals with an oil chamber, and includes a cooling chamber to eliminate the heat produced by the closure. The seals are made of fluoroelastomer VITON.
An initial stage pump is always required. Eight sizes of rotary pumps are manufactured with pre-inlets for nominal flows from 200 to 10,000 m3/h.
