Construction
Mechanical and hydraulic system components:
The compact unit is mounted on a base frame with vibration absorbers . It consists of a group of 2 to 6 high-pressure multistage centrifugal
pumps, which are combined by means of an inlet manifold pipe and a pressure collecting pipe to form a complete system. Each pump is fitted with a shut-off valve on the intake side, a shut-off device on the pressure side and a non-return valve on the pressure side. A module with isolation valves is fitted on the pressure collecting pipe, which contains a pressure sensor and pressure gauge .
For systems with pumps of the Helix V and Helix VE series, an optional 8-litre diaphragm pressure vessel with a throughflow fitting.
Control device :
The control device is mounted directly on the base frame and ready-wired to the electrical components of the system. In the case of larger systems, the control device is accommodated in a separate free-standing cabinet and the electrical components are pre-wired to the corresponding connection cable. The control device is used to control and regulate the SiBoost Smart pressure-boosting system. The size and components of the control device may vary depending on the design and performance parameters of the pumps.
High-pressure multistage centrifugal pumps:
Different types of high-pressure multistage centrifugal pumps are installed in the pressureboosting system depending on the application
and the performance parameters required. Their number can vary from 2 to 6 pumps.

Commissioning
General preparations and control measures
Check that all on-site wiring has been performed correctly, in particular the earthing, prior to the initial start-up.
Check that the pipes joints are not under stress.
Fill the system and subject it to a visual inspection for leakages.
Open the shut-off devices at the pumps and in the suction and pressure piping.
Open the pump venting screws and fill the pumps slowly with water to allow the air to escape completely.
Commissioning the system
After all the preparations and checks have been made, switch on the main switch and set the control system to automatic mode. The pressure sensor measures the pressure at hand and transmits a corresponding current signal to the control device. If the pressure is less than the set start-up pressure, depending on the parameter settings and the control mode, it first switches on the base-load pump and, as required, the peak-load pump(s) until the consumer pipes
are filled with water and the set pressure has built up.
Decommissioning the system
If the pressure-boosting system has to be taken out of service for maintenance, repairs or other measures, proceed as follows:
Switch off the voltage supply and secure it against being switched on again by unauthorised persons.
Close the shut-off devices upstream and downstream of the system.
Shut off the diaphragm pressure vessel at the throughflow fitting and drain it.
Drain the system completely if necessary.
