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 (metal-
lic model), and 969-9347 (plastic model).
Model 969-9337

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.
The metallic model is assembled as shown in the
figure.
Two 6 mm (1/4") internal diameter rubber or plastic
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(s) gets
loose or disconnected 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.
The water temperature must be between +10nC
and +30nC, with an inlet pressure between 3 and 5
bar. This allows a flow of about 200 l/h.
The overall dimensions of the pump when
equipped with the water cooling kit mounted are
shown in the figure below.
