RE: Centrifugal Pump Performance Guarantee
What you might want is a factory performance test, which will give you a certified curve. You'll pay extra for it, of course.
The manufacturer can't guarantee how a pump will perform in your installation, but they can guarantee its performance on the test stand at the factory.

The Hydraulic Institute test code class A is the most stringent.
ISO 9906 is widely used and has 2 classes of acceptance. In my opinion class 1 is ok for most general purpose pumps. Class 2 is so lenient as to be useless.
There are other codes out there such as DIN 1944, API 610, ISO 3555 and ISO 2548, but these are less widely used.
