• Hydro MPC-EF maintains a constant
pressure through continuous adjustment
of the speed of the pumps connected.
• The system performance is adjusted to
the demand through cutting in/out the
required number of pumps and through
parallel control of the pumps in operation.
• Pump changeover is automatic and
depends on load, time and fault.
• All pumps in operation will run at equal
speed.
• Hydro MPC-EDF maintains a constant
pressure through continuous adjustment
of the speed of two CR pumps connected
to external frequency converters, while the
third CR pump is mains-operated.
• One CR pump connected to an external
frequency converter always starts first. If
the pressure cannot be maintained by the
pump, the second CR pump connected to
an external frequency converter will be cut
in. If the pressure cannot be maintained
by the two pumps, a mains-operated CR
pump will be cut in.
• Pump changeover is automatic and
depends on load, time and fault.
• Hydro MPC-F maintains a constant
pressure through continuous adjustment
of the speed of the CR pump connected to
an external frequency converter. The
speed controlled operation alternates
between the pumps.
• One CR pump connected to the external
frequency converter always starts first. If
the pressure cannot be maintained by the
pump, one or two mains-operated CR
pumps will be cut in.
• Pump changeover is automatic and
depends on load, time and fault.
