  • 1. How do centrifugal pumps work in simple terms?
  • Centrifugal pumps operate by converting mechanical energy into kinetic energy and then into pressure.
  • 2. What is a slurry pump?
  • A slurry pump is an industrial pump used to transfer fluids containing solid particles and abrasive materials. They are designed to be highly resistant to wear and corrosion.
  • 3. What is the main function of the impeller in centrifugal pumps?
  • The main function of the impeller is to convert mechanical energy into kinetic energy.
  • 4. What is the main function of the shaft in industrial pumps?
  • The shaft transfers mechanical energy to the impeller.
  • 5. How can I choose the right pump?
  • The selection depends on the type of fluid, its application, the installation location, and other factors. Our experts can guide you to the best possible options based on your conditions.
  • 6. What standards are centrifugal pumps built upon?
  • Centrifugal pumps are manufactured based on standards such as API 610, ISO 5199, ISO 2858, ISO 9906, API 682, and others.
  • 7. How much do centrifugal pumps cost?
  • The price varies based on head, flow rate, material, pump size, and more. Contact our experts for more detailed pricing information.
  • 8. What are the major pump failures?
  • Major failures include cavitation, corrosion, bearing damage, seal leakage, clogged filters, coupling failure, excessive vibration, reduced outlet pressure, impeller wear, and more.
  • 9. Which pump is suitable for which fluid and application?
  • Our experts can assist you in selecting the best pump according to fluid type, application, installation, and your budget and conditions.
  • 10. How can cavitation damage in pumps be prevented?
  • Cavitation damage can be avoided by increasing inlet pressure and reducing pump speed.
  • 11. How is the material of pump components chosen?
  • Material selection depends on the fluid type, operating temperature and pressure, corrosion and wear levels, and the pump’s application.
  • 12. What are the main functions of bearings in industrial pumps?
  • Bearings primarily reduce friction and support the shaft.
  • 13. In which industries are centrifugal pumps used?
  • They are widely used in steel, refinery, mining, power plant, chemical, copper, water & wastewater, firefighting, cement, marine, and food industries.
  • 14. How can pump leakage be prevented?
  • By regularly replacing seals and checking connections, leakage can be prevented.
  • 15. What is the main function of the mechanical seal in a pump?
  • Its main function is to prevent fluid leakage.
  • 16. Why is correct impeller selection important for centrifugal pumps?
  • To improve efficiency and match the fluid type, proper impeller selection is essential.
  • 17. What is the advantage of multistage pumps?
  • They are used to generate high pressure for fluid transfer.
  • 18. Why is it important to use a filter at the pump inlet?
  • To prevent solid particles from entering and damaging the impeller.
  • 19. Why is regular shaft alignment check important in industrial pumps?
  • It prevents bearing failures and increases pump lifespan.
  • 20. How can excessive vibration in a pump be prevented?
  • By ensuring proper installation and alignment.
  • 21. What is the function and advantage of a vortex impeller?
  • A vortex impeller directs fluid in a swirling motion, reducing direct contact with impeller blades, enabling the pump to handle fluids with solid particles without clogging or damage.
  • 22. What are the common types of impellers used in centrifugal pumps?
  • Closed, semi-open, and open impellers are commonly used.
  • 23. In which industries are ETA pumps used?
  • ETA pumps are used in agriculture, water and wastewater, irrigation systems, cooling systems, and more.
  • 24. In which industries are slurry pumps used?
  • Slurry pumps are used in mining, materials processing, oil & gas, chemical, food, and agriculture industries.
  • 25. What materials are used in slurry pump components?
  • Typically, wear- and corrosion-resistant materials such as high-chrome alloys, high-nickel alloys, stainless steel, industrial elastomers, and polyurethane are used.
  • 26. In which industries are high-pressure pumps used?
  • They are used in oil & gas, petrochemical, chemical industries, power plants, urban and industrial water supply, firefighting systems, industrial cleaning systems, and more.
  • 27. In which industries are sewage pumps used?
  • Sewage pumps are used in wastewater treatment, textile, mining, pharmaceutical, hygiene, petrochemical industries, slaughterhouses, and more.
  • 28. In which industries are chemical (CPK) pumps used?
  • CPK or chemical pumps are used in petrochemical, oil & gas, pharmaceutical, hygienic, food, water & wastewater, paint, resin, metal plating, and other industries.
  • 29. In which industries are double-suction (OMEGA) pumps used?
  • Double-suction or OMEGA pumps are used for high flow rates in wastewater, marine, power plants, municipal and industrial water supply, firefighting systems, and more.
