Cooling water is circulated directly through a
cooling jacket in the electronic housing, the
motor casing and finally through a cooling coil
installed in the pump casing of the pumping
chamber. The cooling coil in the spindle pump
casing removes the heat of compression from
the cooling jacket filled with a coolant (factory
pre filled with a mixture of water/glycol, refer
to data sheet). Due to indirect cooling, the
spindle pump casing is maintained at a high
temperature to avoid condensation in the
pump. Likewise, the calcification of cooling
water channels is ruled out to a great extent
due to the high flow velocities. The coolant
supply must be installed in accordance to the
data sheet. The SIHIdry is also equipped with
overheating protection, and the pump will shut
down automatically in case of a temperature
issue.
