Before beginning installation procedures,
these installation and operating instruc-
tions should be studied carefully. The in-
stallation and operation should also be in
accordance with local regulations and ac-
cepted codes of good practice.
1. General description
The UPE Series 2000 is a complete range of circula-
tor pumps with integrated differential pressure con-
trol enabling adjustment of pump performance to the
actual system requirements. In many systems, this
will mean a considerable reduction in power con-
sumption, prevent 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
144
50-120, UPE 65-120, UPE 80-120 and UPE 100-60.
144
The pump offers the following functions:
144
• Proportional-pressure control (factory setting).
145
The head is changed in accordance with the flow
145
demand. The desired head can be set on the
145
pump control panel.
145
• Constant-pressure control. A constant head is
145
maintained, irrespective of flow demand. The de-
145
sired head can be set on the pump control panel.
145
• Constant curve duty. The pump runs at a con-
146
stant speed on or between the max. and min.
146
curves.
147
• Temperature influence. The head varies depend-
148
ing on the liquid temperature.
148
• External fault signal via a potential-free output.
148
• External analog control of head or speed from
148
an external 0-10 V signal transmitter.
150
150
• External forced control via inputs for:
150
- Start/stop,
151
- Max. curve,
151
- Min. curve (night-time duty).
152
• Bus communication. As the UPE Series 2000 in-
152
corporates an input for bus communication, the
152
pump can be controlled and monitored by a
152
GRUNDFOS Pump Management System 2000 or
153
a building management system.
153
• Remote control. The pump can be operated by
153
means of the GRUNDFOS wireless remote control
153
R100.

2. Applications
157
158
The UPE Series 2000 is designed for circulating liq-
159
uids in heating systems. The pumps can also be
160
used in domestic hot-water systems.
161
UPE Series 2000 is suitable for:
161
• systems with a constant flow where it is desirable
162
to optimize the setting of the pump duty point and
162
• systems with variable flow-pipe temperatures.
2.1 Pumped liquids
Thin, clean, non-aggressive and non-explosive liq-
uids, not containing solid particles, fibres or mineral
oil.
In heating systems, the water should meet the re-
quirements of accepted standards on water quality in
heating systems, e.g. the German standard VDI
2035.
In domestic hot-water systems, it is advisable to
use UPE pumps only for water with a degree of hard-
ness lower than approx. 14°dH.
For water with a higher degree of hardness a direct-
coupled TPE pump is recommended.
The pump must not be used for the trans-
fer of inflammable liquids such as diesel
oil, petrol or similar liquids.
