Dynamically sealing repeller
eliminates the need for
conventional mechanical seals
No mechanical seal is needed
during operation as centrifugal
force created by a spinning
repeller (expeller) removes fluid
from the seal chamber. When the
pump is stopped, a static seal is
used to keep it from leaking.
The need for external flushing
and process contamination
control are eliminated.
Standard Mark III A... or optional
ANSI 3A power end shown here
(See page 8)
Optional ANSI 3A power end
offers three-year performance
guarantee
Available with most of the
standard and optional features
of the Mark III ANSI Standard
pump
Applications
Tough services where sealing
is difficult
Services where a flush is
undesirable (e.g., evaporator
feed)
Continuous, around-the-clock
service
Batch operations where a “run
dry”condition might exist
