CAUTION
Leaking expansion joint
Flooding of installation room!
▷ Regularly check for cracks or blisters, exposed fabric or other defects.
ü The expansion joint has a length limiter with solid-borne sound insulation so as
to be able to absorb reaction forces.
1. Install the expansion joint in the piping free of twist or distortion. Never use the
expansion joint to compensate for misalignment or mismatch of the piping.
2. Tighten the bolts evenly and crosswise during assembly. The ends of the bolts
must not protrude from the flange.
3. Do not apply paint to the expansion joint. Protect it from any contact with oil.
4. The position of the expansion joint within the pressure booster system must
allow easy access and inspection and it must, therefore, not be insulated along
with the piping.
5. Expansion joints are subject to wear.
6.4.2 Installing a pressure reducer
NOTE
A pipe length of approximately 600 mm must be provided on the inlet side to
accommodate a pressure reducer, if necessary.
NOTE
A pressure reducer must be installed
- if the inlet pressure fluctuation is too high for the pressure booster system to
operate as intended or
- if the total pressure (inlet pressure plus shut-off head) of the pressure booster
system exceeds the design pressure.
The maximum pump discharge pressure at zero flow point is reached in manual
mode.
A minimum pressure gradient of 5 metres is required for the pressure reducer to
fulfill its function. The pressure downstream of the pressure reducer (downstream
pressure) is the basic parameter for determining the pump head.
For example:
The inlet pressure fluctuates between 4 and 8 bar. A pressure reducer is needed
upstream of the pressure booster system on the inlet side.
Min. inlet pressure (p
inl
)=4bar
Min. pressure gradient=0.5bar
Downstream pressure=3.5bar.
6.5 Installing unpressurised inlet tanks
Installation and location of an unpressurised inlet tank together with the pressure
booster system are governed by the same rules applicable to the pressure booster
system.
Install the closed PE inlet tank (under atmospheric pressure) available as a KSB
accessory as described in the installation instructions supplied with the tank.
CAUTION
Contamination in the pressure booster system
Damage to the pumps!
▷ Clean the tank before filling it.
