High - pressure intake
(Julia HP)
Inlet line
• Install a filter on the suction side of the jetting pump, filtering
capacity 200-360 µm and allowed flow 3 times as much as the pump
nominal water flow.
Warning: install a filter on the suction side of the
jetting pump, filtering capacity 200-360 µm and
allowed flow 3 times as much as the pump nominal
water flow.
• Minimum water supply head: 0.20 m.
• Optimal average water speed inside the piping: slower than 0.5m/s.
In any case pipe diameter should not be narrower than the intake pipe.
• Avoid narrow turns and any pressure drop that can cause
cavitation.
Discharge line
• First part of discharge piping must be made of flexible hose in order
to damp down pulsations produced by the pump.
• Install a safety valve correctly set.
• Average optimal speed inside the piping: below 5,5 m/s. In any case
the piping diameter shall not be smaller than the pump outlet port
diameter.
• Check the piping to be clean before starting the pump.
• For further information in regards to high pressure pump installation,
refer to the manufacturer use and maintenance manual. Pay particular
attention to:
-
Set up;
-
Mode of use;
-
Maintenance.
• Fig 4.4 represents a possible set up for the high pressure water line.
