1.1 - Introduction to multipump systems
10
10
By multipump systems we mean a pump set made up of a number of
10
pumps whose deliveries all flow into a common manifold. The devices
10
communicate with one another by means of the connection provided
10
(wireless).
11
12
The group may be made up of a maximum of 4 devices.
12
A multipump system is used mainly for:
12
12
• Increasing hydraulic performance in comparison with a single
12
device
14
• Ensuring continuity of operation in the event of a device devel-
14
oping a fault
14
• Sharing out the maximum power

1.2 - Making a multipump system
15
The hydraulic plant must be created as symmetrically as possible to
obtain a hydraulic load uniformly distributed over all the pumps.
The pumps must all be connected to a single delivery manifold:
For good operation of the pressure boosting set, the following
must be the same for each device:
• hydraulic connections
• maximum speed
1.3 First start of the multipump system
Make the electric and hydraulic connections of the whole system as
described in par 2.1.1, 2.2.1 and par 3.1. (see Instructions for installation
and maintenance e.sybox).
Switch on the devices and create the associations as described in para-
graph 1.4 - AS: Association of devices.
1.4 - AS: Association of devices
Allows connection/disconnection with the following devices
•
e.sy
Other e.sybox pump for operation in a pump set
•
composed of max 4 elements
