Runners according to your design
Forged or casted monoblock impellers from CNC TVAR
Rotor is the heart of any prosulsor. 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.

Manual polishing
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.
- Polishing based on CMM measurement report
- Experienced employees polishing according to customer specific procedures
- Several dimensional and quality controls through process
- Compliance with all environmental standards thanks to the newest filtering technologies
Non-destructive testing
Completed products are checked using four non-destructive testing methods (NDT). Our inspectors are ISO 9712level II certified.
- Visual Testing (VT)
- Liquid Penetrant Testing (PT)
- Magnetic Particle Testing (MT)
- Ultrasonic Testing (UT)

Balancing
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.

3D measurement
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.
- Measurement of drawing dimensions
- Measurement of hydraulic profile
- Part alignmenet based on RPS points
- High data quality
