The pump maintains a constant speed at any flow
rate. The desired speed is set on the interface
panel of the pump.
The nominal differential pressure set point is modified
based on the fluid temperature. Uses an external
temperature sensor.
The pump maintains a constant differential pressure
at any flow demand until the maximum speed is
reached. The desired head of the pump can be set
via user interface. Recommended for use in systems
with small or constant pressure losses.
The pump maintains a constant temperature in a system,
such as domestic hot water system or a single temperature
heating system. Uses an external temperature sensor.
The differential pressure continuously increases or
deceases based on the flow demand. The set point
head can be set on the pump user interface. Use for
systems with large pressure losses.
The pump will optimize the energy consumption by identifying the ideal duty point.
Air purge will remove the dissolved gases from the pump.
The pump will automatically reduce speed when there is an abrupt
change in fluid temperature. The change in fluid temperature is from a
boiler operating in night time setback mode. The external temperature
sensor is used. (Fixed Speed, Constant Pressure, Proportional Pressure)
One 0-10V (Analog): Speed Control by external controller
One external temperature sensor input for temperature modes. Sensor Type: KYT38, P/N: 104502
