1-1/2” is the diameter of the suction and discharge for the 2-bolt models.
STANDARD OPERATING MODES
Constant Speed
The pump maintains a constant speed at any ow rate. The desired
speed is set on the interface panel of the pump.
Constant Pressure (Δp-c)
The pump maintains a constant differential pressure at any ow
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.
Proportional Pressure (Δp-v)
The differential pressure continuously increases or deceases based
on the ow demand. The set point head can be set on the pump
user interface. Use for systems with large pressure losses.

Night Mode
The pump will automatically reduce speed when there is
an abrupt change in uid temperature. The change in uid
temperature is from a boiler operating in night time setback
mode. The built-in temperature sensor is used. (Fixed Speed,
Constant Pressure, Proportional Pressure)
CONSTANT TEMPERATURE SPEED CONTROL
T- Constant Control
This control mode will use a PI algorithm to vary the speed of the pump
in order to maintain a constant temperature of the uid media.
ΔT-Constant Control
This control mode will use a PI algorithm to vary the speed of the pump
in order to maintain a constant differential temperature between the
built-in temperature sensor and external temperature sensor.
