RESEARCH AND DEVELOPMENT
SM PUMPS R&D continuously performed research activities to improve pump hydraulic performances, flow conditions and rotor – dynamic pump characteristics.
Design and development of pumps for Nuclear and Oil&Gas application is based on serious research works on following:
- •Flow conditions through the pumping hydraulic channel, pressure and velocities distribution, vortices
- •Cavitation research
- •Recirculation study
- •Stability
- •Stress, thermal and fatigue analyses
- •Vibration, noise analyses
Requirements for pumps for nuclear power plants are very high and very specific. Design criteria should provide high reliability and high performance of the pumps.
API 610, ISO 13709 international standards specifies requirements for pumps for petroleum, petrochemical and natural gas industry.
Requirements for pumps for other application usually consider basic design requirements with some additional requirements.
