5. Hose Requirements

Pump nozzle A :
left: outlet to application (pressure side)
right: return flow from application
Hoses are normally used to connect the pump to your
application.
Hose length depends mostly on the size, form and material
of your application. The length of a hose and its diameter,
combined with the circulating capacity, have a large affect
on the temperature control effectiveness. Whenever
possible, use a wider hose diameter and place your
application as close as possible to the circulator.
High operating temperatures will lead to high temperatures on the
hose's surface, even more so at the metal nozzles. In this case avoid
touching the hoses and nozzles.
The required hose material depends on the heat transfer liquid.
Hoses must not be folded or bent. Use a wide radius if turns have to be
made.
Hoses may become brittle after prolonged use, or they may get very
soft. Check hoses regularly and replace them when necessary.
Secure all hose connections using hose clamps.
