Rotor is the heart of any pump. It is a center of the suction. Close attention to design of blade angles at inlet and outlet is necessary, as these are major parameters affecting power production. We understand how important it is to have a perfect surface to avoid cavitation in the high speed rotation. This is why CNC TVAR manufactures all runners from forged blocks or high quality castings consisting of premium alloys no matter the number of blades, size, or rotor design. We understand the need for the highest possible efficiency and make sure, it is not just on the paper. Thus, CNC TVAR provides a long-lasting, high-quality product.
Purchasing of stainless steel, titanium and aluminium from top European suppliers. Delivery time depending on specifications and size.
Grinding and polishing – thatʼs where the parts get their final touch. When it comes to the surface quality of complex shapes, we do not make any compromises.
Completed products are checked using four non-destructive testing methods (NDT). Our inspectors are ISO 9712level II certified.
The actual unbalance is displayed in one or two planes by graphical and numerical output. There is also a deviation from the allowed unbalance displayed and a suggestion for the most convenient weight correction.
The measurement is performed on CMM or with a 7-axis high speed 3D arm with a laser scanner with extreme precision according to the highest international standards.
