2. Applications
The UPE Series 2000 is designed for circulating liq-
uids in heating systems. The pumps can also be
used in domestic hot-water systems.
UPE Series 2000 is suitable for:
• systems with a constant flow where it is desira-
ble to optimize the setting of the pump duty point
and
• 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
oils.
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.
3. Installation
When installing pumps, types UPE 32-80 F,
UPE 40-80 F and UPE 50-80 F, with oval bolt holes
in the pump flange, washers must be used as shown
in fig. 1.
Fig. 1
See mounting dimensions at the end of these in-
structions.
The pump must be installed with the motor shaft hor-
izontal, fig. 2.
Fig. 2
Arrows on the pump housing indicate the liquid flow
direction through the pump, fig. 3.

3.1 Terminal box positions
The terminal box can be turned to the positions
shown in figure 4. However, these positions must be
checked with the “x” markings indicated in the tables
below:
The pump must not be used for the trans-
fer of inflammable liquids such as diesel
oil, petrol or similar liquids.
Care should be taken to ensure that per-
sons cannot accidentally come into con-
tact with hot surfaces of the pump.
