Vent Accessories

Figure 45
Two rubber or plastic hoses from the water supply must be fitted to the two
water cooling banjos.
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 +10°C and +30°C, with an inlet
pressure between 3 and 5 bar. This allows a flow of about 200 l/h.
The water electrical conductance must be ≤ 500 µs/cm. When the conductance
NOTE
is higher, in closed water circuit, the use of up to 20% of Ethyl-Glycole is
suggested.
Vent Accessories
The vent valve and vent device allow to avoid undesired venting of the pump
during temporary power failure and enables an automatic vent operation.
