WATER COOLING KIT INSTALLATION

Two types of water cooling kits are available to be
mounted when the pump is used under heavy load
conditions or when air cooling is insufficient.
The two model part numbers are: 969-9337 (me-
tallic model), and 969-9347 (plastic model).

CAUTION
The items of the plastic model kit must be assem-
bled as shown in the following figure
The assembled kit must be screwed into the suit-
able holes of the pump body with a recommended
closing torque of 5 Nm.
Two 6 mm (1/4") internal diameter rubber or plas-
tic hoses from the water supply must be fitted to
the two nozzles.
These hoses must be held on the respective noz-
zles using hose clips to avoid that the tube do not
detach during operation.
The plastic model must be screwed into the suit-
able holes of the pump.
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 be-
tween 2 and 4 bar. This allows a flow of about 10
l/h.
The water electrical conductance must be
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.
