Limits for Pump Head
LPP-2000.20
Pump Head
LPP-2000.7
“High Flow”:
Typical data for pump head LPP-
2000.22
Operation with controllers LPC-
2000.x and motors LPM-2000.x
Curves are representative for pump
head LPP-2000.14
The cavitation limits have been
determined for water. They can be
different for other liquids and depend
also on the hydraulic circuit design.
For example: higher inlet pressure
reduces cavitation effects.
“Hybrid”:
Typical data for pump head LPP-
2000.21
Operation with controllers LPC-
2000.x and motors LPM-2000.x
The cavitation limits have been
determined for water. They can be
different for other liquids and
depend also on the hydraulic circuit
design. For example: higher inlet
pressure reduces cavitation effects.
“High Pressure”:
Typical data for pump heads LPP-
2000.7 and LPP-2000.20.
