Frequently asked questions
Can a replacement be selected from the flange size alone?
No. The duty point, impeller configuration, speed, motor, dimensions and material compatibility also need to match.
Are all NIS and NISF pumps made from the same material?
No. Check the complete model code and the supplier material schedule for the wetted components.
