Screw pump to API676

Screw pump to API676

Screw pump to API676

(OP)
Dear All
This is my first time posting my question on this Eng-Tips, I got screw pumps installed in our new power plant. I would like to know how to make an performance acceptance test. According to API676 there is no detail criteria for this. For example; pump head, flow rate, efficiency and power input tolerance. I found the acceptance test criteria in API610 which is centrifugal pump. If anybody has suggestion please let me know.
Regards
Pootong

RE: Screw pump to API676

I've been told that the Hydraulic Institute Standards thoroughly covers the testing of rotary and displacement pumps. Testing of these should closely parallel the procedure for centrifugals since the objectives, methods and measurements are about the same. Besides performance, noise and vibration are also usually tested.
