thread378-310492: Flygt N-series pump
I am reviewing a N-Impeller Clog proposed pump where it was clearly stated that solids this pump is capable of passing has to be 4 inches.
Wondering why Xylem can't claim that their Neva Clog impeller are capable of passing x inches debris.
Can someone provide more information about it?

Flygt claims their pump has less clogging even though the throughlet size is smaller.

I'll read this.
RE: N-Impeller Clog
We specify 5 different brands that we're used to work with + a criteria of 4 inches minimum.
RE: N-Impeller Clog
The solids-handling capability of the pump is customarily defined as the solid-sphere size that will pass through the pump. It is accepted in the industry that passing a sphere 75 mm (3 in.) in diameter is require for smaller pumps and that a 100-mm (4-in.) sphere is acceptable for virtually all capacities. It should b noted that a restricting area may exist in the pump casing as well as in the impeller, and the pump specification should clearly indicate the minimum sphere diameter for the pump, not just for the impeller.
However, there is no globally accepted clog test standard.
The answer to your query would be for Flygt to provide a list of references of similar size pump installations and you can call and verify whether the pumps have clogged.
