Technical Features; Installation; Emplacement; Hydraulic Installation - Espa CKE Serie Gebrauchsanweisung

With this type of regulation it is much easier to control
energy usage than with unregulated systems.
Another advantage of CKE booster set is that it
reduces pressure surges and softens peak currents,
thereby prolonging the life of the pump.
CPE
The ECD control panel provides direct control of one
or two pumps. If connected to 2 ELV panels, you can
control the pressure booster sets of 3 or 4 pumps.
These units are made of the highest quality materials
and undergo strict testing and controls.
WARNING: Adequate compliance with the
installation and operating instructions, as
well as the electrical connection diagrams,
ensures proper equipment functioning.
DANGER: Not following the instructions in
this manual can lead to motor overloads,
diminishment in technical characteristics,
reduction of equipment life and all types of
other consequences,
disclaim any liability.

2. TECHNICAL FEATURES

 Degree of protection: IPX5.
 Temperature of the fluid: from 4ºC to 40ºC
(Multi VS from 4ºC to 120ºC)
 Maximum temperature the ambient: 40ºC.
 Continuous duty (S1).
 Clean water without suspended particles.
 Maximum working pressure: depends on the
model of the installed pumps, will be PN6, PN12
or PN16.
 Minimum input pressure: depends on the NPSH
curve of the installed pumps. Recommended not
work with input pressure more than 4mca.
 Maximum input pressure: the input pressure plus
the maximum pressure of the pumps must not
exceed the maximum working pressure.
 Number of starts per hour:
- For motors up to 3 kW, a maximum of 60
starts/hour
- For 4 kW motors, a maximum of 40
starts/hour

3. INSTALLATION

The equipment is delivered on a pallet,
protected against humidity and dust. It may
only be transported using authorised lifting
systems. The transporting pulleys and cables are
fastened to the openings on the plate specially
designed for this purpose. Collectors should not be
used as fastening points for lifting the load.
Remember that the set's centre of gravity is
displaced towards the top.

3.1. Emplacement

The ESPA pressure booster are designed to work
indoors. The equipment should be installed in a dry,
well-ventilated location that is large enough to
enable equipment maintenance. A floor drainage
system is also required.
The maximum temperature of environment is 40ºC.
In general, the groups of pressure cannot work in the
following conditions:
1 - Outdoors
2 - In places at the risk of flood.
3 - In places with insufficient ventilation.
for which we
4 - In places where the temperature exceed 40ºC.
5 - In places where dangerous atmospheres exist
6 - In places where there exists the possibility of
7 - In places where risk of frosts exists.
The measures of the place will have to be such that
allow the operations of maintenance with facility,
also it must save a sufficient space for the installation
of the accumulator.

3.2.1. Installation diagram

The installation must comply with the legal
requirements in the location where the equipment is
to be installed.
The raising system must be designed in such a way
that it can be delivered to areas fed by network
pressure, without the need to start up the set.
CPE sets should be connected to membrane
pressure devices that are appropriate for the
characteristics of the installation. The inflation
pressure is 0.5 bar less than the opening pressure.
Each CKE pressure set comes with a suitable
pressure tank which can adequately lessen pressure
variation in the area of the transducer reader. The
inflation pressure should be 0.8 bar less than the
reference pressure. For safety reasons, the pressure
tank is delivered unassembled and therefore must
be assembled before it can be used.
equipment from being affected by noise and
vibrations. The pressure booster set must be fixed
on the above mentioned support by screws across
the existing orifices.
In CKE sets, the pressure transducer that comes
with the equipment receives the pressure signal from
