self-cooling
SIHI ZTN Pumps feature a special dual-
action heat insulation chamber which
enables self-cooling without any coolant!
Located behind the impeller, the chamber
acts as a "heat barrier" to provide
favorable
temperature
characteristics.
The reduced temperature at the driven
end allows the use of viton radial shaft

and

side the heat losses are minimized to
Save Energy.
The ZTN self-cooling design eliminates

and

pipework-effectively reducing installation
and operating costs. (See Photo)
