• Control MPC Series 2000 maintains a
constant pressure through adjustment of
the speed of the pumps connected.
• The 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, operating hours and
fault.
• All pumps in operation run at the same
speed.
• The number of pumps in operation is also
depending on the energy consumption of
the pumps. If only one pump is required,
two pumps will be running at a lower speed
if this results in a lower energy
consumption. This requires that the
differential pressure of the pump is
measured and pump curve data are
available for the controller.
