TECHNICAL INFORMATION
WATER COOLING KIT INSTALLATION
Two 6 mm (1/4") internal diameter rubber or plastic
hoses from the water supply must be fitted to the
two nozzles.
NOTE
These hoses must be held on the respective noz-
zles using hose clips to avoid that the tube do not
detach during operation.
The water cooling kit mod. 969-9318 must be in-
stalled when the pump is used under heavy load
conditions or when air cooling is insufficient.
The kit is assembled as shown in the figure.
Cooling may be carried out either through an open
circuit with eventual discharge of the water, or us-
ing a closed circuit cooling system.
In both cases, the water temperature must be be-
tween +10°C and +30°C, with an inlet pressure
between 3 and 4 bar. This allows a flow of about
30 l/h.
NOTE
The water electrical conductance must be
≤
500
µs/cm. When the conductance is higher, in closed
water circuit, the use of up to 20% of Ethyl-Glycole
is suggested.
The overall dimensions with the water cooling kit
mounted are shown in the figure.
