Quiet operation
The XL-11
®
Precision-Crafted Bearing System, advanced fluid
passage design and B&G permanently lubricated motor come
together to deliver smooth, quiet, maintenance-free performance.
Internally self-flushing seal
Bell & Gossett’s open-seal chamber design provides superior
flow circulation around the seal faces, resulting in reduced heat
buildup, increased particle removal and superior seal-face flushing.
It all adds up to long, trouble-free seal performance.
Impeller
State-of-the-art hydraulically balanced
impellers and resilient-mounted motors
provide smooth, quiet operation.
