Description and function

6.1 Description of the pump (Fig. 1.1 Appendix on page II, Fig. 1.2
Appendix on page III)
The UPE high-efficiency pump is a series of glandless pumps
with integrated electronic regulation, which enables the
performance of the pump to be adapted automatically to variable
load states of the system.
This ensures optimum system efficiency in all operating modes
and with all loads, as well as the highest possible energy savings
on the pump side.
The regulation module has an axial design and can be found on
the motor casing (Fig. 1.2 Appendix on page III item 5), with up
to three types of automatic output adjustment (depending on the
type of pump):
6.1.1

Types of differential pressure regulation

The selectable types of regulation are:
 p-c: The electronics maintain the differential pressure

produced by the pump constant at the selected differential
pressure setpoint HS (up to the maximum characteristic
curve) across the entire permissible volume flow range.

Pump with operating button

The red button on the front of the regulation module (Fig. 1.1
Appendix on page II and Fig. 1.2 Appendix on page III) is the
central operating element with the setting ranges.

NOTE
The minimum and maximum setting values for the delivery height with
regulation types p-c and p-v depend on the pump type and can be
 
determined from the characteristic curve.
If the setpoint for the delivery height set via the red button falls below the
minimum setting value, then the pump operates at the minimum setting
Hmin for this type of regulation.
If the setpoint for the delivery height set via the red button exceeds the
maximum setting, then the pump operates at the maximum setting Hmax.

The key advantages of this electronic regulation are:
 Energy savings and reduced operating costs at the same
time,
 Reduction of flow noise,
 Fewer overflow valves required, e.g. in static heating
circuits.
 p-v: The electronics change the differential pressure

setpoint value to be maintained by the pump linearly
between ½Hs and Hs. The differential pressure setpoint
decreases or increases depending on the discharge rate.
