5. What is a submersible pump?
A pump designed to operate while fully submerged in water, pushing water to the surface.
6. Where is it used?
In borewells, agriculture irrigation, domestic water supply, industries, sewage, and drainage.
7. What are the types of submersible motors?
- Water-filled
- Oil-filled
8. Can a submersible motor run dry?
No. Dry running damages winding and bearings.
9. What are common failure reasons?
- Dry running
- Voltage fluctuation
- Sand/mud entry
- Wrong installation
- Motor winding failure
10. What is an openwell submersible pump?
A pump installed inside an open well, tank, or sump. Both pump and motor remain submerged in water.
11. Where is it used?
For agriculture, domestic water lifting, and industrial water circulation from open wells, ponds, or tanks.
12. What is the difference between borewell and openwell submersible pumps?
- Borewell submersible: Installed in narrow boreholes, deeper applications.
- Openwell submersible: Installed in open wells or sumps, shallow to medium depth.
13. Advantages of openwell pumps?
- Easy installation
- Lower maintenance
- Can handle fluctuating water levels
14. What is a monobloc pump?
A pump where motor and pump are a single compact unit mounted on a common shaft. Common in domestic and small-scale applications.
15. Where are monobloc pumps used?
- Domestic water supply
- Agriculture (small farms)
- Industrial circulation
- Pressure boosting
16. What are the types of monobloc pumps?
- Centrifugal monobloc pumps
- Self-priming monobloc pumps
17. What is the advantage of monobloc pumps?
- Compact design
- Easy installation
- Low cost
- No separate alignment needed
18. How do I select the right pump?
- Application (domestic, agriculture, industrial)
- Required head (height)
- Discharge capacity
- Power availability (single-phase or three-phase)
- Water source (borewell, openwell, sump, tank)
19. Why does my pump trip often?
- Overload
- Low/high voltage
- Motor winding fault
- Impeller jammed
- Capacitor failure (single-phase)
20. How often should pumps be serviced?
- Minor check: Every 6–12 months
- Major Service: Every 2–3 years, depending on usage and water quality.
21. Can I use the same pump for hot water?
No, standard pumps are for normal water. For hot water, special high-temperature pumps are required.
