Centrifugal Pumps
Application
Suitable for use with clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
As a result of their reliability and the fact that they are easy to use, these pumps are widely used in domestic and civil applications such as the distribution of water in combination with small and medium sized pressure sets, for transferring liquids and for the irrigation of gardens and allotments. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather.

FAQs
1.What is the lifespan of a centrifugal pump?
With proper maintenance, a centrifugal pump can last 10–20 years, depending on usage, fluid type, and operating conditions.
2.Why is my centrifugal pump losing pressure?
Possible reasons:
Worn impeller or casing
Air leakage in the suction line
Clogged strainer or pipe
Incorrect motor speed (VFD issues)
3.How can I prevent pump cavitation?
Ensure proper NPSH (increase suction pressure if needed).
Keep the suction line short and free of restrictions.
Avoid running the pump at excessively high speeds.
Use a booster pump if necessary.
