15
The Grundfos UPE(D) FZ is a range of circulator
15
pumps with differential-pressure control enabling
15
adjustment of the pump performance to the actual
system requirements. In many systems, this will
15
reduce the power consumption considerably, reduce
16
noise from thermostatic valves and similar fittings,
16
and improve the control of the system.
16
The desired head can be set on the pump control
18
panel.
20
These instructions apply to the pump types
20
UPE(D) 80-120 FZ and UPE 100-120 FZ.
21
The pump offers the following functions:
22
•
Proportional-pressure control (factory setting).
The pump head is changed in accordance with
23
the flow demand. The desired head can be set on
24
the pump control panel.
24
•
Constant-pressure control.
24
A constant head is maintained, irrespective of the
25
flow demand. The desired head can be set on the
pump control panel.
26
•
Constant-curve duty.
26
The pump runs at a constant speed on or
between the max. and min. curves.
