Inlet pressure:
If using lower inlet pressure than stated in above
table, the pump will cavitate, which will damage
the pump.
The inlet line connection must be properly
tightened as entrance of air will cause cavitation.
Outlet pressure:
MAWP (Maximum Allowable Working Pressure)
must be within specifications.
If pump operates below minimum outlet
pressure, it may cause cavitation/erosion in the
pump.
Note: We recommend that the pump unit
includes a pressure gauge at inlet and outlet.
Dry running:
When running, the pump must always be
connected with water supply in order to avoid
pump damage.
Disconnection:
If inlet line is disconnected from the water
supply, the pump will be emptied which will
cause dry running.
When starting up again, follow the bleeding
procedure described in section 4: Initial start-up.
1)
For lower pressure, please contact Danfoss High Pressure Pumps
2)
If inlet pressure exceeds inlet operating pressure, Danfoss recommends inspection of the pump and shaft seal
