Manufacturers typically test centrifugal pumps with water to develop a pump performance curve that they provide to their customers. But what if a customer is using that pump for a fluid other than water? Is the pump curve representative of how the pump will perform in their system?
Listed below are some pump performance characteristics and key fluid properties. At a given flow rate, what do you expect the pump performance to do?
- The working fluid has a higher density than water
- Head increase / decrease / stay the same
- Power increase / decrease / stay the same
- Efficiency increase / decrease / stay the same
- The working fluid has a higher viscosity than water
- Head increase / decrease / stay the same
- Power increase / decrease / stay the same
- Efficiency increase / decrease / stay the same
