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.

and resilient-mounted motors provide smooth,
quiet operation.
