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.
