Description and Function

6.1 Description of the pump

This 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 pump also offers 3 constant levels, each with a set speed
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.

Installation and electrical connection

The installation and the electrical connection must be carried out
by specialists and in compliance with the local regulations!
ATTENTION!
WARNING! Risk of personal injury
The regulation module cannot be dismantled. If the regulation module is
separated from the pump by force, there is a risk of personal injury:
 During generator operation of the pump (rotor driven by primary
pressure pump), a dangerous voltage occurs on the motor terminals,
which are not protected against access.
Due to the remaining electrical connection on the regulation module

7.1 Installation

 The system/pump must be installed in a dry, well-ventilated
room protected from frost.
 The system/pump must not be installed until all welding and
soldering work is completed; the pipe system must be
flushed if necessary.
ATTENTION!
CAUTION! Risk of material damage
Any impurities in the pipe system can destroy the pump during operation.
Flush the pipe system before the pump is installed.

Table 6.1:
The essential 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 H
decreases or increases depending on the discharge rate.
ATTENTION!
WARNING! Risk of personal injury
Observe the valid accident prevention regulations.
ATTENTION!
WARNING! Risk of electric shock
It must be ensured that there are no risks resulting from electrical energy.
Instructions resulting from local or general regulations (e.g. IEC, VDE
etc.) and from local utility companies must be observed.
 The installation
downstream from the pump is recommended. This means
that it is not necessary to drain and re-fill the system when
the pump is replaced.
 Carry out tension-free installation. The pipes must be
mounted such that the pump does not bear the weight of the
pipes.
 The flow direction of the medium must correspond to the
direction triangle on the pump casing.
