2. General description
The Grundfos UPE(D) FZ is a range of circulator
pumps with differential-pressure control enabling
adjustment of the pump performance to the actual
system requirements. In many systems, this will
reduce the power consumption considerably, reduce
noise from thermostatic valves and similar fittings,
and improve the control of the system.
The desired head can be set on the pump control
panel.
These instructions apply to the pump types
UPE(D) 80-120 FZ and UPE 100-120 FZ.
The pump offers the following functions:
•
Proportional-pressure control
(factory setting).
The pump head is changed in accordance with
the flow demand. The desired head can be set on
the pump control panel.
•
Constant-pressure control.
A constant head is maintained, irrespective of the
flow demand. The desired head can be set on the
pump control panel.
•
Constant-curve duty.
The pump runs at a constant speed on or
between the max. and min. curves.
